Looking back
In any case, it turned out to be a very significant year for Apple. Apple stock is on a tear and the impact of the iPhone will be felt for years to come. The Mercury News rightly says that they have transformed the mobile phone industry. The next few years will see Apple setting the pace and the rest of the industry trying to catch up, much as they did with the iPod.
In April, I wrote about location based services and their promise. I was disappointed they did not take off in a big way in 2007. I think that this will be corrected in 2008, perhaps again with Apple leading the way ?
The other big technology trend in 2007 was the push behind Clean Tech, and Solar energy in particular. As we got close to the end the year, we saw NanoSolar announce production shipments and Ausra announce a contract with PG&E. I am sure this is just the beginning of an explosion of activity in clean tech in the years to come, with the Valley driving innovation again.
In a few days, I will share some of my predictions for technology trends in 2008. Till then, happy holidays and a great New Year to everyone.

A Great Day for Clean Tech in the Valley
The other interesting news, which did not quite get as much coverage, was that PG&E had agreed to buy 2MW of power from wave energy from a Canadian company, Finavera Renewables. Wave energy has always been a promising and challenging source. As the data I presented from Dr. Amit Kumar's talk in October showed, the theoretical potential for geothermal and ocean power is 70 TW, but feasible capacity is expected to be on the order of 2TW and significant technical challenges remain. Good to see that PG&E is driving the leading edge of wave energy. Clearly compared to the practical possibility of 1200 TW from solar (again from Dr. Kumar's data), this is small, but we may need all the sources we can get, if we are to stem impending doom in the form of catastrophic climate change. :-)
Lest you think I exaggerate, listen to what NASA scientists had to say yesterday in San Francisco (video clip from ABC News). The report says that by 2012-2013 the Arctic will be ice free at the end of summers. This was not expected to happen till 2040, previously. Let us hope that alternative energy is still in time to save the planet.

Social Lending
So, when I got an invitation to a Social Lending panel organized by the MIT Club of Northern California on December 5th, I was intrigued. I was curious to see how Web 2.0 had changed this age old practice :-) The panel was hosted at Wilson Sonsini Goodrich & Rosati in Palo Alto and moderated by Eric Nee, Editor of the Stanford Social Innovation Review. The panelists included John Witchel, CTO of Prosper, Patrick Gannon, SVP of Lending Club and Harvey Grasty, Head of Business Development of MicroPlace, a division of Ebay. Prosper and Lending Club have been funded by Valley VCs to the tune of $40M and $10M respectively and MicroPlace has access to a lot more funding, potentially, as part of Ebay. Prosper is the oldest of the three, having been around since early 2006, while MicroPlace launched their website in October 2007.
The concept is simple - peer to peer lending. Anyone can be a lender or a borrower. All you need is to be able to surf the web and create an account at one of the sites. The three companies have somewhat different approaches to the process, though. In all three cases, you can lend small amounts of money, as low as $25, for short periods of time, and you can choose who you will lend to. They charge a service fee of 1% in all cases. Microplace has altruistic goals of eliminating global poverty, while Prosper and Lending Club are focused more on borrowers in the United States. Microplace partners with third parties like the Calvert Foundation and others to make low interest (2-3%) loans in other countries, especially underdeveloped countries. You cannot make loans to individuals in other countries directly.
Prosper has over 500,000 registered users and $100M in loans so far, $40M in VC funding and 45 employees. They claim transparency of the process as their biggest advantage. The borrowers submit detailed information on their background and requirements and the lenders can choose who they want to lend to based on risk and return. Prosper has an automated lending process which either party can customize based on their preference. Risk is assessed based on Experian Scorex credit scores and other criteria. The borrower needs to provide a fair amount of personal info for lenders to assess, though not as much as typical banks require. The minimum credit score is 520.
Lending Club started as a peer to peer lending service for college alumni on Facebook and received $10.26 M in VC financing in August 2007. They have $3.25M in loans so far with $25M turned down. The average rate of return is 12.25% and minimum is 6.78%. The average FICO score is 692. Their users range from students to 70 or 80 year olds. The lending process is automated like Prosper. They view themselves as combining responsible credit with social networking.
All three companies claim that their process is far simpler than borrowing money from a bank, there is more transparency, a higher rate of return and the flexibility to loan money to people or causes you find interesting. They claim their default rates are low and that they assist in helping fight fraud and securing privacy. However, they have all been around a lot less than most banks, are less capitalized and are a lot smaller in people terms than the smallest of banks. If the security and privacy issues do not limit them and they grow to service a large volume of loans they have the potential to be profitable and change the banking paradigm. If, for example, you can borrow money at 7-10% to pay off $20000 in credit card bills, it looks like a win-win situation for the borrower and lender, by cutting out the middleman. As John Witchel of Prosper stated, they have many more product ideas like 5 year loans and others for the future. If they are successful in banking, there are other areas such as insurance where consumers have even less choice, which look to be possible growth areas.
I must say that these companies are fine examples of the innovative thinking that is the hallmark of Silicon Valley and the Bay Area. Whether they are successful over the longer term remains to be seen. But, the world is a better place for the attempt and surely will bring some competition to an industry which has not changed in ages, and the average consumer will benefit from it. Certainly, if the villagers in India have access to the Internet and to websites like Microplace, they will get a better deal than they could from the local moneylender, or even the local bank :-)

The Wireless Wars
The bidders for the spectrum include the usual suspects like AT&T and Verizon and some new players like Google and Frontline Wireless, a startup funded by stellar Valley VC's ! So, why such a diversity in the bidding ? - because the stakes are big ! It has a lot to do with Net neutrality and control of the Internet. For example, see this perspective from the man who has some claim to having invented the Web, Tim Berners-Lee. :-) See, not quite who you thought it was :-).
Its all about control of information, and in an information age that equates to a lot of power. The Mercury News column talks about interesting angles to the bidding, such as Google bidding, but not to win. Interestingly, it all ties back to the mobile phone operating systems and Android, which I wrote about earlier in the week. This auction also appears to be the last of the spectrum auctions for useful spectrum. The deadline for bids is this Monday and the results will be announced early next year according to the Mercury News. I can't wait to see who wins this one. It could change the power structure in wireless communication. I will make a prediction - the bid will be a lot more than the $4.6B minimum that the FCC expects for the spectrum.

Clean Tech VC funding skyrockets
One big difference I see between clean tech funding and funding for the other areas is that the size of the deals is very large. However, one deal listed for $500M to Delta Hydrocarbon, a Dutch company, to enhance oil field production did not seem to me to be particularly clean tech. But, maybe there is a clean tech angle to it :-). If at least some of the clean tech funding sticks in the Valley, it certainly will drive the level of activity up.
On Tuesday, Google made a splash with their announcement targeting 1 GW of renewable energy at prices cheaper than coal. This is an ambitious target and they are willing to spend millions chasing it. Though there are differing views of it, I for one, hope they make it. They have the deep pockets to try and if they achieve the target it will make a significant difference. To understand how difficult this is, read my post from last month where I quote Dr. Amit Kumar's data which shows coal at 5c/kWh compared to the cost of other renewable energy sources.

Mobile Phone Operating Systems - Open or Closed ? - Part II
The first question the panel considered was - why the push for an OS on mobile phones now ? The consensus seemed to be that phones have grown to become mini-PCs with many applications and power management requirements and lots of peripheral functionality, larger screens and other capabilities. With this level of sophistication and the constrained power requirements a targeted OS was required. There was some discussion on what was really open or closed. Microsoft claimed that since there were 100,000 people downloading their SDK and about 18000 apps built on their platform, they could be considered an open platform. One of the panelists pointed out that the baseband functionality in Google's Android was not open sourced for security and other reasons. Symbian pointed out that FCC regulations governing usability prevented some of the control code being open sourced. There was no closure on this discussion.
The panel talked about having the full browser or Outlook on a mobile phone and seemed to agree that it was about context and not about having the full functionality. Alan Brenner, SVP of Blackberry platforms for RIM commented that data usage was less than 10% on mobile phones today and as the usage climbed more applications would be enabled. Rich Miner's (Google) view was that today's smart phone was tomorrow's feature phone.
There was heated debate among the panelists on the cost of the mobile phone OS. One view was that it was insignificant with relation to the overall cost of the device. Rich Miner of Google pointed out that some phones which are available to service provider customers for $100 typically cost about $50 and Microsoft was charging between $10-$12 for the operating system with the Opera browser, which was not insignificant. Microsoft's Gerardo Dada responded that Microsoft provided value for the cost and that they spent significantly on R&D compared to the rest of the industry. Microsoft did acknowledge that the trend of giving away software and generating revenue from service was something that they see and have ways of addressing. Symbian's VP of US Operations, Jerry Panagrossi pointed out that free code was not necessarily good, especially if it was poorly tested. Alan Brenner quotes the CEO of Verizon saying that the return rate on open devices was over 40%, while the return rate on Blackberries was only 3%. In all, a fairly lively debate :-)
The panel deplored the lack of control of the features and settings on mobile phones today and attributed it to control of the ecosystem by the carriers and mobile phone OEMs. This was expected to reduce over time. Alan Brenner mentioned the availability of the Blackberry Unite(?) next month which would allow changing settings. Nokia's Victor Brilon mentioned that you can do this on some Nokia smart phones today by downloading software and using a USB connection. He pointed out that some of the difficulty with opening up the settings was the cost of the ensuing support requirements.
The panel seemed to agree that much of the increase of rate of growth in mobile phones would come in emerging markets in Asia and Africa with data services growing in India, China and Africa. Today with 250M phones in the US, the market was 80% penetrated. However, Andy Seybold said that could go to 300% with users having multiple devices. This is certainly true of many people I know. Though, there is the possibility of integration as with the iPhone. People certainly do not like carrying more devices than they have to.
The panel discussed the opportunity for application developers. Most of the panelist companies have active developer programs. However, Rich Miner of Google pointed out the lack of return for many application developers for mobile phones. Very few companies which were funded to do mobile phone apps generated successful exits. Part of the reason for this was the considerable fragmentation in the market and lack of opportunities for sales to end customers. (However, ring tones did generate significant revenue for some people, mostly in Asia. ) Google is giving away $10M to applications developers to write apps for Android, though ! I am sure there will be some interest in that :-)
In any case, a very interesting panel which made it clear that all the major software players were going to give of their best to control a large fragmented market.

Mobile Phone Operating Systems - Open or Closed ? - Part I
It was a very lively panel, as was to be expected with some strong competitors in close proximity and Andy as a moderator. I was on a panel he moderated a few years back at UC Berkeley and there clearly was no lack of strong opinions :-) The Valley mobile phone company conspicuous by their absence was Apple. That was a pity, but they rarely show up for events except their own. Though, you could almost sense the industry responding to the challenge of the iPhone. Nokia explicitly mentioned that they had been beefing up their presence in the Valley. So, the Mercury News column on Sunday was close to the mark. The Valley is seen as a center of innovation and every major player wants a piece of the action. The panel discussion did touch upon this as well as the impact of emerging markets and globalization.
There were a range of interesting topics covered during the session and I want to mention the highlights, at least. However, I will save this for my next post later in the week. Stay tuned.

Silicon Valley and Globalization
There are some interesting statistics on the flow of venture capital to and from the rest of the world in the print edition. The charts don't show up in the link above for some reason. Perhaps, this is the most striking change from the '90s, when money flowed into the valley and stayed here. This led to the tech boom and the bust, of course. The Valley has recovered somewhat, but its far from the affluence of 2000. Perhaps, the return to glory for the valley will be in the form of the clean tech boom.
The Valley however, is still very attractive to the rest of the world. One other trend the Mercury News discusses is the ramping of the Valley presence of big tech companies like Nokia and Microsoft who seek to be closer to ideas, partners, investors and customers. As the column says, it appears the world is flat and Silicon Valley is at the center of it and the next wave appears to be clean technology. I will root for that.

Thankful in the Valley
Then again, I would much rather be in Silicon Valley, than in say, Bangladesh, where people are fighting to stay alive. The poor country continually faces severe calamities such as this and struggles to get back on track. The World Bank and the rest of the world are pitching in with their help, but for those going through the ordeal life must be tough indeed. Yes, we in Silicon Valley and the U.S.A. have a lot to be thankful for.

Green Hummers and Zero emission SUVs ?
Phoenix is targeting that niche space of truck and SUV owners who also want to be green. Clearly, these are not your typical Prius owners :-) . But, I was rather impressed as the story unfolded. Phoenix is an Ontario, California company. Their zero emission trucks have a range of about 130 miles on a full charge and take about 10 minutes to recharge ! They can get up to speeds of about 95 mph with a full payload and go 0 to 60 in 10 seconds. ! Not your average Prius :-) To achieve this they have a special combination of motor, battery technology and a few other innovations. The Nanosafe battery from Altair Nanotechnologies is a key component. These Li-Titanate batteries take only 10 minutes to charge from an offboard charger. They take about 6 hours to charge from an onboard charger hooked up to a 220V supply. The infrastructure deployment to make these off-board chargers available widely is an issue which will take time to overcome. Altair Nano's battery technology appears to be impressive, in that it overcomes the slow charge time problem. Apparently, they are targeting other applications such as a 4MW storage facility for windpower.
Phoenix buys the chassis from a Korean supplier and outfits it with their technology. There are two 35kWh battery packs on board to give the 130 mile range. The batteries can outlast the vehicle itself and can be recycled. They require a special connector to enable the 10 min charge. Otherwise they can hookup to the same chargers that other electric cars use. A typical charge costs about $3.70 and to get a range similar to a diesel truck probably around $7.40, compared to a full tank of gas at about $60. Very impressive economics. Even if gas prices were to fall this vehicle would be economical ! The truck costs about $50, 000, so more expensive than other trucks. But, Phoenix claims lifetime cost is about 76c/mile which is comparable to other trucks.
Currently, they are targeting fleet sales only and have customers like PG&E and NASA lined up. They plan to open up to consumers by 2009. With 17M automobiles sold in the US and 39M worldwide they have a large addressable market. Even if they sell in the 100,000 units only they expect to be profitable in 18 months. They have raised over $100 M so far. No big name VCs shown on the web page, though. They are partnering with others for nationwide distribution.
Clearly, they are playing in a high stakes game. Today's Mercury News reports on a court rejection of Bush's truck fuel standards. Schwarzenegger's shown as applauding the decision. As Dan Elliott pointed out, both gasoline based automobile and electric car camps have their own lobbies. The electric car lobby does seem to be gaining some strength recently. I remember electric car designs at MIT as early as the '80s sponsored by GM and other major car manufacturers. But, they never went far in the market :-) . Both their mileage and market clout have increased in recent years with major manufacturers introducing electric cars and hybrids and the public showing an increasing tendency to buy and drive them. Interestingly, this month's Fast Company magazine has an article on Jonathan Goodwin who claims he can get 100 mpg out of a Lincoln Continental and cut emissions by 80%. Yes, he works on Hummers too. See, the title of this blog was not all fake :-) He claims he can get 60 MPG on a H3. So, what are the major car manufacturers missing ?
The automobile industry requires deep pockets. Its not every day you see a new automobile company, Tesla notwithstanding. The last one was DeLorean and we know how that ended. But, I must say that I am impressed by Phoenix's approach of applying their innovation where it matters, and not trying to reinvent the wheels (literally) :-) Even if they do not have the muscle to set up their independent manufacturing, distribution and financing networks, they appear to be able to ship trucks and collect revenue on them. Their careful choices in product and market strategy seem viable. I hope they are successful, because it will drive the rest of the auto industry to follow. I'll wait to buy my Hummer :-)

Wild markets, tech companies and solar tax credits
The emerging clean tech hot companies like First Solar and SunPower were hit big time losing over 14% each just today. First Solar went up over $50 on Thursday, Nov. 8th and has almost given up all the gains by today. These and other clean tech related stocks were particularly hard hit because of the rumor that Solar investment tax credits would expire in 2008 because of a pending energy bill without provision for these. Of course, these could bounce back just as rapidly should the reports prove false. But for now, the bad news just keeps piling up on an already jittery market. It would be interesting to see when all this hits bottom and starts climbing back.

Bionic Bodies ?
Dr. Gautam opened the session with some statistics on the biomedical industry. 50% of all biomedical companies worldwide are in the US and over 2500 of them are in California. The Bay Area including Silicon Valley has over 700 and Sunnyvale is one of the hotspots for biomedical devices ! This is probably logical since the proximity of Silicon Valley's semiconductor industry, the medical research from Stanford, UCSF and other universities coupled with access to venture capital must make for an interesting combination. The panelists gave their view of what the next hot thing was. Dr. Butte suggested that perhaps there was more value in understanding the impact of genetic analysis than in having the analysis itself widely available with lower cost chips. The solutions which used the chips in end applications to improve a particular problem were likely to be more popular. Today this knowledge is limited. The panel considered the question of body reactions to implanted silicon sensors. The view was that much like stents have been designed with coatings which make them less susceptible to rejection, new technologies would be developed to overcome this problem.
The panel considered the question of the best mechanism to foster transfer of technologies between the biomedical and semiconductor industries. Semiconductor companies which target the biomedical space hire experts in the field to understand the space and define products. Similarly biomedical companies also sometimes hire semiconductor experts or acquire teams with this expertise, especially when developing biochips or arrays. However, they pointed to the inability to have access to specific semiconductor process technology to optimize biochips. Not many biomedical companies have the luxury of owning a fab :-)
The panel considered the impact of outsourcing technology in the biomedical industry. Today diagnosis assistance such as reading X-rays is sometimes outsourced, but its far from a perfect situation. There are also regulatory hurdles to such practice. The question of which device areas would be impacted by MEMS was answered by Alissa Fitzgerald and MIT Club officer and MEMS expert, from the audience. The primary areas seem to be in cardiac or cardio-thoracic devices.
The panel did consider the issue of cost of biomedical devices and why they are not impacted by cheaply available technology. The semiconductor component cost of many of these devices is a small fraction of the total cost. The fact that the medical device industry is not an open, competitive space is part of the issue. After the lengthy regulatory approval process, the devices are supplied to patients and are paid by a small group of insurers. The cost is added up among the many layers in the system. So, even if technology scaling of cost and performance were to be applied to these devices there would be no quick reduction in cost. This is partly the reason for the high cost of health care in the US without the commensurate benefit. Strange how a capitalistic society is not so capitalistic in some critical areas :-)
However, with access to technology much better health care is possible. The panel talked about many new advances such as robotic surgery devices which could perform much more complicated surgeries than humans could perform, with far more success. This will drive the growth of a whole new way of praticing medicine, with doctors being trained to use these devices to achieve very high levels of surgical sophistication. Intuitive Surgical and Accuray are two Valley companies which provide such devices today. Clearly, Silicon Valley is going to be at the center of such exciting innovation in the years to come.

Ausra contract from PG&E - Milestone for solar thermal power
As I discussed in my blog a couple of weeks back, the cost/kWh of most alternative energy sources, especially solar, is unattractive compared to current grid rates. However, legislative requirements for utilities provide a powerful incentive for renewable energy. Ausra is well positioned, because solar thermal power is reasonably cost effective and the company has powerful Silicon Valley backers such as Vinod Khosla, Kleiner Perkins and others. With paying customers such as PG&E and the end users such as you and I, the VCs will clearly see return on their investment. This might very well start the alternative energy Gold Rush ;-)

California Clean Tech Open Awards 2007
There were six categories - Smart Power, Air Water and Waste, Green building, Renewables, Transportation and Energy efficiency. Each of the winners got $50,ooo in cash and $50,000 in services from the sponsors. The awards in each of the categories were handed out by the respective sponsors.
There was an impressive list of speakers from the US DOE, California Energy Commission, NRDC and Nth Power (a Clean Tech VC). Dave Rodgers from the US DOE stole a march by inviting the winners to Washington DC (at the DOE's expense) to present their entries before the DOE for potential sponsorship. I was also impressed by the winners acceptance speeches. They had honed their pitching skills during the summer with the CCTO's series of events preparing the finalist teams to refine their business plans for the final submission. This was one of the main attractions for us when we entered the event. The results of the process were impressive. Each of the winners were able to articulate their value proposition succinctly. From years of experience I have learnt that this is a very valuable skill to have when pitching to VCs.:-) You have them in the first few minutes or you don't :-)
From that perspective all of the finalists for the CCTO were winners. They have gained valuable insight into the process of taking their companies to the next step. The awards event also had a showcase for the finalists. The companies represented were impressive and I am sure many of these will make it even without the CCTO prizes. There was strong VC representation in the audience. The networking opportunity was great. Met Google's energy Czar, Bill Weihl who handed out the Google green building prize. Nice title to have :-) Met several folks from the MIT Clean Tech Entrepreneurship series who were volunteering to put on the CCTO. The number of volunteers for the event was impressive - well over 350. Shows the level of interest in clean technology. If some of the companies participating in the CCTO succeed, they will serve to put California in a leadership position in the clean energy movement. Even without the CCTO prizes these companies are also likely to attract much VC interest. In fact, I ran into at least one VC looking for a good clean tech opportunity and was able to introduce one of the finalists to an energy company representative. My little contribution to the clean tech crusade :-)

Solar Energy - Heat or Hype ?
Dr. Amit Kumar did his Ph.D research in Photovoltaics at Stanford and Caltech in the late 80s and early 90s, and is now CEO of a publicly traded biomedical company and is on the boards of several solar energy companies. The talk was well laid out and had a wealth of data drawn from a variety of sources including Dr. Kumar's own estimates.
Current worldwide energy use is 14-15 Terawatts (TW), with the US consuming about 4 to 5 TW. Of the total worldwide energy consumption, about 12TW is from fossil fuels, 1.5TW from hydroelectric and biofuels, 1TW from nuclear and 0.2 TW from all other including solar. In 30-50 years this 15 TW is expected to grow to 30TW from population growth, emerging nations consumption and economic growth. One of the estimates which surprised me was the fact that about 3.5TW of the 4TW US consumption came from transportation related energy consumption (planes, trains, ships and automobiles). The vast infrastructure put in place to deliver oil and gas worldwide from raw material to consumable gasoline enables it to be sold at prices cheaper than most other liquids except tap water. :-)
If fossil fuels continue to be the primary source we will continue to pump carbon into the atmosphere (currently estimated at 8 billion tons/yr) aggravating any existing problems. Dr. Kumar estimates resources for oil, gas and coal to be 120, 300 and 1500 years, respectively. He then considered each of the alternative energy sources in terms of their opportunities, challenges and potential to supply the global energy requirements.
Cleaning up fossil/bio fuel use with carbon sequestration methods allows continued use of fossil fuels with less of their problems. However, challenges here are entropy, cost, capacity and leakage. Without technical breakthroughs it does not look easy. Geothermal and ocean tides have the potential to supply 70 TW, but economically feasible capacity is on the order of 2TW and installed capacity is minimal.
Hydroelectric has a gross potential of 4.6TW and installed capacity of 0.6TW in 1997 and a possible 0.3TW more production increase. Problems include capital cost and issues like the relocation of a billion people (?) for the Three Gorges dam in China. In India, I am aware of some projects shelved due to environmental impact.
Wind energy has a theoretical land potential of 10 TW and practical potential of 2TW. Offshore potential can be up to 5TW. But, wind power is intermittent, needs storage and has distributed generation restricted to some areas only. It is viable, supplying at close to grid power rates where it is deployed.
Biofuels like Ethanol need large land areas for cultivation and have energy densities close to half of gasoline and cost more in energy to make than we can get out of them. They are also water resource limited for cultivation. If all available land is cultivated 8-10 TW is possible, but practical potential is 1-2TW. Their primary attraction is being able to use the existing fossil fuel distribution infrastructure and subsidies.
Nuclear fission is a viable alternative, and much capacity is deployed worldwide and even in the US. Estimate that 20% of US power is nuclear. Waste disposal, uranium availability and weapons and terrorism concerns are major issues. To get 10TW we need 10000 plants, which seems like quite a lot to build. So, delivered capacity from nuclear is limited to the number of 1GW plants that will be built.
Solar has a theoretical potential of 120,000 TW if irradiation of the whole earth's surface is considered. Practical possibility is about 1200 TW. To deliver 3-4 TW at 10% solar cell efficiency needs land area of about 250miles x 250 miles or 62500 sq miles. Currently we have about enough solar modules to cover 50-100 sq. miles. Even this is a $30B market. So, we have a long way to go :-) Maybe, the high PE of the solar panel makers are justified :-) But, there's more to this story. One of the limitations of solar energy is that its not very concentrated. Rooftops and other viable sources can only provide about 10% of the surface area required. The rest has to come from generating installations which can be capital intensive. One can see why many startups are targeting this space. Capacity is increasing, but nowhere near what is required. Silicon may be a limitation even at current levels.
One main issue with solar energy has been the cost. While coal, gas, oil, wind and nuclear have generating costs between 5-8 c/kWh, (with coal the cheapest at 5c/kWh), solar energy costs about 25c/kWh. This does not even include the costs for storage and distribution. Dr. Kumar quoted his thesis advisor, who compared funding solar energy generation to funding the Apollo mission if Southwest were to provide $29 shuttle missions to the moon. Clearly, in spite of these economics, many VCs are pumping billions of dollars into solar energy. Other challenges for solar include inverters for DC-AC conversion and storage.
Cost may be reduced with scale, manufacturing improvements and new types of cells. Efficiencies range from about 25% for crystalline silicon to about 15% or lower for CIS/CIGS, CdTe, amorphous silicon and nano TiO2. The market is dominated by single crystal silicon (92+ %). followed by CdTe, CIGS and particle based cells. Exotic structures like tandem cells and paints are in their infancy. Most of the non-Si technologies have still not achieved the scale of manufacturing capability that is required. Till they do, its too early to make a call on their viability and scaling possibility.
New opportunities in solar include new types of cells and structures, storage and inverters, thin film material and cells, silicon supply and other materials, installation and repair, electric vehicles and catalysts for hydrogen evolution. Cost reduction is a major challenge. The environmental impact of some of the technologies used is another.
Dr. Kumar concluded that in the midst of a global energy crisis we are forced to look at alternatives to fossil fuels and solar is clearly one of the better alternatives. But, we also need massive changes to our way of life, conservation and more efficient products for lighting and transportation and an effort in alternative energy bigger than the Manhattan and Apollo projects. Dr. Kumar can be contacted at amitoptigon (at) hotmail (dot) com.
I am glad that I attended this talk, because it gave a broad overview of many different alternative energy methods and their relative impact and potential. However, the answer to the question of how much of the solar buzz is hype and how many bumps there will be in the road between now and when solar energy is a viable energy alternative to fossil fuels, is still elusive. With oil close to $90/barrel, its easy to fund alternative energy work. But, what happens if oil were to go back to $20/barrel ? Maybe with the impact of global warming being felt worldwide, there would still be an impetus to drive alternative energy. But, with more oil accessible from the less ice-locked Arctic and Greenland, does it drive a vicious cycle of more oil based economies ? :-)
If I were to guess, the VCs will fund more solar energy companies. Silicon Valley will continue to be at the center of much of this action. There will be a few phenomenal successes, as there were in the Internet boom days, and there will be a few fadeouts. However, there will be much energy generated(pun intended :-)), lots of action and excitement and a few millions to be made for the entrepreneurs and investors. The valley will have contributed to global development in yet another realm, maybe with more impact than the previous semiconductor and internet cycles. The more things change, the more they remain the same :-).

How Green is the Valley ?
Meanwhile, Ed Gunther of the Gunther Portfolio forwarded me this interesting tidbit on the economics of solar technology in developing countries. Solar panels in public installations are being stolen. Readers will find this amusing, and something most solar experts had not counted on in solar technology expansion. But, that's the way technology is sometimes viewed by the poorer segments in a developing nation. Arguably, India is no longer a developing nation. But, there is significant poverty still in the country. I remember hearing stories of people stealing copper strips used in lightning conductors on tall public buildings, when I was a student. But, copper has gained so much in value that these thefts occur even in Silicon Valley these days :-) Clearly, there is even more incentive to cost reduce solar technology. :-)
Ed also sent me this interesting link from MIT on how students can prepare themselves for a career in solar energy. To me this is rather uncharacteristic of MIT :-) MIT rarely handheld students, lest they not learn how to blaze trails. But, the Laboratory for Photovoltaic Research has chosen acceleration of the adoption of PV as its mission, and I say more power to them :-) I would love to see MIT be the leader in yet another "hot" technology :-)

Clean Tech, Mergers and Acquisitions etc
Meanwhile, Silicon Valley is on a roll. The pace has picked up not only in the Internet space and Web 2.0, but in alternative energy too. Nanosolar raised $100M in June 2007 and is setting up manufacturing in San Jose and in Germany. Not to be outdone, another thin film CIGS company SoloPower of Milpitas raised $30M in July. Its interesting how the Internet and alternative energy fields intersect. The Google founders are investors in Nanosolar. But, that's always been the story of the Valley. The semiconductor entrepreneurs of the previous generation from Fairchild, Intel, National Semi and others became VCs at Kleiner, Sequoia and other firms and they invested in a host of new technologies and companies including Google and Yahoo, which have in turn grown to become giants of their own. If anything, the pace has accelerated in recent years. The Valley is as fertile in innovation as it was in the days of the fruit orchards of the early 20th century. Meanwhile, Fairchild has turned 50 and the Valley is moving even faster with its innovation. Sometimes the more things change, the more they remain the same, however. One could look at the new alternative energy companies, especially in solar energy as related to semiconductor technology.
Mergers and acquisitions have always been an integral part of the Valley scene. On September 20th, the MIT Club Semiconductor Entrepreneur Series hosted an event on " How to Negotiate an Acquisition Term Sheet" at Cooley Godward in Palo Alto. This was an interesting event where two Cooley attorneys, Jenneifer Fonner DiNucci and Jane Ross negotiated a hypothetical acquisition term sheet. They covered the highlights of the negotiating strategy and the structure of the term sheet. There is wide variation in these deals and the devil is in the details. Interestingly, they pointed out that the bigger billion dollar deals tend to be simpler in structure than the smaller million dollar deals. The whole discussion and audience participation was very illuminating and covered the acquirer, acquiree, VC, investment banker, attorney and employee perspectives.
Talking of billion dollar deals, sometimes they don't work out the way everyone wants. Today Ebay announced a writedown of the Skype acquisition. The co-founder and CEO, Zennstrom apparently leaves with an accelerated payment. The earn-out agreement on that term sheet must have been interesting :-) Meanwhile, Zennstrom is probably concentrating on his next venture Joost and a spectacular exit for it as well. Its interesting how quickly Scandinavia has adapted to the Silicon Valley model :-)

Google acquires Peakstream ?
This is a good example of how the Valley, startups, VCs and their networks work. I am sure if Peakstream was located in India or Australia with the same technology, this acquisition may have worked more slowly or not at all. But, then maybe they have the technology because they are in the Valley ? :-) Clearly, the rest of the world may take issue with that :-)
Interestingly, the Register also has a spotlight on shades of 1998 :-) Some interesting analogies !

Portable Power Sources
Scott Chou pointed out that Clean Energy was rapidly gaining favor in the VC world with $2.36B in funding of 124 deals in 2006 vs $820M and 74 deals in 2005. Of this funding Ethanol/biofuels/clean coal topped the list with solar a distant second in total funding, though the number of deals was 34 to 27. He then discussed the impact of energy density. Diesel gives about 11000 W-hr/liter while methanol at the low end is only about 4400 W-hr/liter. Other biofuels span the range. In comparison a Li-ion batter is about 400 W-hr/liter, though its not quite a useful measure for this application. He also touched upon the negative impacts of biofuels in driving up the costs of food crop and the search for non-food crop as sources of biofuel. Interestingly algae topped his list delivering 95000 liters of oil/hectare with the nearest competitor being chinese tallow at 6545 liters of oil/hectare. So, the algae win hands down :-) This was a nice overview of the clean energy scenario as it stands. Thanks to Scott for all the data.
The panel's focus of course was on portable power sources. The worldwide battery spending is on the order of $60B, with $20B of that going to rechargeable batteries. So, it certainly is not a niche market. Zinc Matrix appeared to be the leading contender for the longest lasting batteries for laptops and other portable devices. No wonder Intel Capital is an investor. However, the PowerMems technology seems to challenge it with charges lasting for the lifetimes of the device, on the order of years. However, the application is for relatively low power wireless sensor devices requiring power in the mW range. Their technology harvests ambient energy from vibrations, heat and solar energy and stores in a 3D nanostructure battery. Their focus seems to be mostly on the broad spectrum efficiency of power generation and less on the storage, though. Polyplus has interesting technology where they focus on Lithium-seawater, Li-sulfur and Li-air batteries. You would expect that seawater, despite having the advantage of being a plentiful electrolyte, would pose some corrosion problems. However, the key to their technology is the ability to keep the Li anode chemically protected while being electrochemically active. They claim energy densities of 6000 W-Hr/liter. Then there was PowerGenix, who developed next generation Ni-Zn batteries. They claim to be cheaper and smaller than Ni-Cd and Ni-Mh batteries and promise an upset in the rechargeable battery space.
Overall a very interesting panel, with fuel cells being the only key missing technology - the Ultracell panelist could not make it. Clearly, battery technology is the key challenge in portable devices. Device performance follows the almost exponential semiconductor scaling and the power requirements follow, but battery technology barely keeps up a linear improvement in performance and almost no cost reduction. Truly revolutionary approaches are needed if the status quo is to budge by much. Certainly this panel provided some interesting approaches to this very challenging problem.

California Clean Tech Open
The kickoff event itself was quite interesting. An impressive lineup of speakers and a panel discussion was all contained in a hour and half with a great networking reception. For a complete list of speakers see the link above. The panel discussion, very ably moderated by Kerry Dolan of Forbes, gave an opportunity for senior executives from the sponsors, SDG&E, SCE, ENVIRON Corporation, PG&E, Google, AMD and Lexus to talk about their initiatives in Clean Technology.
Brad Barton from the US Department of Energy spoke of the strong interest and initiatives in alternative energy programs at the DOE. Bob Cart, CEO of GreenVolts who won the Renewables Prize in 2006 described how they entered the CCTO with a summary and ended up with a complete business plan, funding and support. The company has since raised $1.5M in VC funding. Matt Caspari, CEO of Aurora Biofuels who won Transportation Prize first runner up did even better with $5M in VC funding. Raj Atluru, Managing Director at Draper Fisher Jurvetson gave a VC perspective of interest in clean technology. He talked of the tremendous growth of interest in clean technology funding among VCs. His particular focus was on technologies improving efficiencies of clean energy generation.
The closing speech by John Garamendi, Lt. Governor of California was frank and stirring. He pointed out that the innovation spurred by the CCTO and entreprenuers in California solved only part of the problem. Without serious policy changes to address global warming, these innovations would not address the whole host of problems generated. Some of these issues, where a few inches of increase of sea level would salinate major sources of fresh water supply in California, or where the rise in temperatures could lead to tropical parasites and diseases could not be fully addressed by these innovations. So he exhorted the public to push for major policy changes to address the larger issue.
The networking reception which followed was very good. Many of last year's winners were present to discuss their companies and technology. I had an interetsing discussion with Dave Culp, President of KiteShip which provides wind power assist for ships. He was part of the America's Cup design team in 2003. It will be interesting to see who the winners are for 2007. I am tempted to write up a 3 page summary by June 30th. Now all I need is a good clean tech idea :-)

Mars Rover Mission at the Tech Challenge
For the S.A.G.A the day did not start off too well. True to form S.A.G.A had come up with another Jules Verne like device held in air by helium balloons and propelled by four electric motors driving large propellers as directional thrusters.
The Tech Museum hands out about 18 awards for each section, roughly 1 in 5 teams entering get some kind of award. The awards started with a good number going to Cupertino High School (the SAGA's school) and almost an equal number going to rival Monta Vista. Imagine my shock when the style awards were announced and the S.A.G.A got the first one of two! You can check out all the award winners here. You just have to click through each one patiently. The team had pulled it off for the fourth year in a row. Their team work and enthusiasm had converted almost certain defeat into victory.
The final tally on the awards was Cupertino High 6 - Monta Vista 6. Rather impressive, because I think Monta Vista is academically a superior school and certainly more competitive. But, certainly the Cupertino High teams were tough competitors too. I guess a lot of the credit goes to some teachers like Chemistry teacher DeMuth and Biology teacher Ujifusa who encourage their classes to participate and award them class points for participation. Both teachers were there in person during the weekend cheering and capturing the events on videocam. That's dedication in teaching for you. I guess they are some of the few along with the organizers of the Tech Challenge who impart the spirit of innovation and a love of engineering and creativity to our children in Silicon Valley.
To Melissa McAlexander, Brittany Sabol and others at the Tech Museum who run the Tech Challenge, I can only say thank you for helping bring the spark of creativity to the kids in Silicon Valley. I am rather proud that some of the Tech Challenge organizers are also MIT alumni, because, at least in part, I am sure, they drew some of their inspiration from the other Tech. I am proud to have been associated with the S.A.G.A. of the Flaming Chicken these last four years. They grew from a group of friends who dreaded technology to some who dream of taking at least an engineering minor in college. When I look back on these times, I am sure I will say these were the good old days, and I am sure the kids who participated in the Tech Challenge will say the same.

20th anniversary of the Tech Challenge
I have been associated with the Challenge since 2004, when Melissa McAlexander, who runs the Tech Challenge, roped me into volunteering as an advisor to teams from Lowell Elementary in San Jose. The challenge that year was Pick a Pike. There were about 30 kids from Lowell in our group assisted by 5-6 advisors. Most of these kids had never entered a design contest, let alone win a prize. We spent about 10 to 12 weeks with the kids helping them understand the challenge and getting them to think about ways of solving them. The kids formed about 5 teams and played a bit, fought a bit, and fooled around a whole lot. In the end, though, they did come up with some rather clever solutions which caught the pike - plastic fish floating in a tub of water. When 3 out of the 5 teams won prizes, their joy knew no bounds. For the advisors it was an exhilirating experience.
The same year, my son Arjun and his friends, who were in Cupertino High decided that they also wanted to participate in the Tech Challenge and I ended up being nominated their advisor too. This was quite a different kettle of fish. High school kids rarely want any guidance or advice. They just wanted money for the supplies and to be driven to places where they could buy stuff. Their design was a catapult which looked like a medieval flame thrower. It caused great excitement among the audience in its operation because it was powered with bungee cords and tended to be dramatic in its launch, when it threw a net into the tub to catch the fish. Strangely enough, they went on to win a prize that year for the "Most Courageous Team".
In 2005 the challenge was Battle the Blaze. Arjun and his friends put together yet another medieval looking device and and again won an award for "Simple Elegance". The team had renamed themselves as The S.A.G.A of the Flaming Chickens. One of the team members designed some rather cool T-shirts for the team and another dressed up in a yellow chicken suit for the event. In 2006 the challenge was Fight the Flood. The team stuck with the same name and came up with a strange manually driven conveyor belt which scooped the sand. They got an award for Teamwork. All along that was what they excelled at.
They have a team again in 2007, with most of the original members. They have always considered themselves "tech challenged" and worked at coming up with solutions low on technology and high on creativity. Rather, odd for Silicon Valley kids, at least the technology part. Over the years I have seen them goof off, fight, slack off, put in last minute efforts and come up with crazy ideas. But, in the end, they have enjoyed the process and learnt a lot from it.
The team has always worked well together and enjoyed solving the challenge together, but I notice a definite change in their attitude towards engineering and technology. They seem to have developed a genuine liking for it. Even my 9 year old, who is a constant, and sometimes unwelcome, supporter and critic at their team meetings is inspired by their efforts. Truly, the Tech has done something right in inspiring creativity, teamwork and a love for engineering and design in kids. Certainly from all accounts in the press, the US is falling behind in technology education. But, in my experience from the last four years, the Tech Challenge seems to have found the magic recipe for teaching creativity and engendering a love of engineering in kids.
Tomorrow is D-Day at the Tech Museum where the kids will bring their devices for the Challenge. It is bound to be a high energy and fun day as in past years. I am looking forward to it. Regardless of whether Arjun's team wins, I am sure they will have a lot of fun and so will I. For me, it is the last year I will be part of their team as they participate in the Tech Challenge. Its my way of rejuvenation and bonding with my son and his friends before they go off to college. Fortunately, Krishnan, our younger son will be able to sign up for the Tech Challenge in a couple of years, to help keep me continually young. :-)

Location based services, applications and products
The panel consisted Mike McMullen, VP, Sprint PCS, Jaap Groot from Tedyo Holding Inc., Greg Turetzky from SiRF, John Ellenby from GeoVector and the Director of Marketing from Loopt. They were pretty unanimous in their opinion that every mobile device would have location based capabilities very soon. SiRF is one of the earliest semiconductor companies to offer discrete GPS silicon. For cost, power, accuracy and availability reasons, the technology has been slow penetrate the cell phone space. The main chip suppliers for GPS are TI, Qualcomm and SiRF. In spite of the Federal mandate to associate a physical address with the telephone number of a person calling 911 in the US, GPS is still not universal on all cell phones. The mandate is met in different ways by providers. Some providers who have GPS in all cell phones meet E911 requirements indoors by cell tower triangulation and outdoors by GPS. However, cost and accuracy limit the capability. Today most GPS enabled devices cost around $200. When the chip costs drop to $1, significantly more devices will be enabled.
As one of the panelists quoted an ex-Trimble employee, " every object has an inherent right to know where it is". Accepting this thesis, one can easily see a wide range of applications for location based services such as - finding devices not in your hand, finding friends (who want to be found :-)), emergency services, increasing what you can see beyond what is possible now and so on. Today from a service provider's point of view, the cost to find the location of a friend on the network is about 20c. Loopt, a Sequoia funded startup, for example, sees a wide range of possibilities for social mapping of friends. GeoVector's technology adds direction to position information thus enabling a wider range of possibilities for location based services. They claim to "enable finding stuff where you are not and getting to it".
As with most technology, promise takes a long time to deliver. But, it certainly appears that a veritable explosion of location based devices and services are on the horizon. Soon, we will be expecting location capabilities on every reasonably valuable device we own from cell phones, to cameras and even sneakers, not to mention embedding this capability on pets and children. Surely, one is led to believe that Silicon Valley and the Bay Area will once again be a prime mover in this high potential space, if one follows the example of SiRF, Loopt and GeoVector.

MIT Club event on Communications in Emerging Markets
The panel consisted of John Gardner from Nokia Growth Partners, John Sherry, Director of Social Science Research at Intel's Digital Health Group, Kristin Peterson, Co-founder and Chief Development Officer for Inveneo and Michael Kanellos, Senior Editor at CNET News.com. The panel was moderated by Julie Ask, Senior Research Director at Jupiter Kagan. The diverse panel had some surprising agreement on many things. All of them agreed that cell phones beat PCs as communication devices in emerging markets by a large margin. They mostly agreed that this was due to cost rather than ease of use. John Sherry talked about Intel initiatives targeted at emerging market applications for PCs such as ruggedizing, dust proofing, using alternate power sources etc. However, sometimes these led to increased cost which made the devices less attractive in these markets. Also, it was incorrect to assume that all customers in emerging markets wanted the lowest cost devices. There was significant demand for higher end capabilities.
Mike Kanellos described the range of uses these devices can be put to in emerging markets. In countries in the Middle East with large immigrant populations from India and Phillipines, PCs with video conferencing capabilities in Internet cafes are used to visually communicate with families back home. Cell phone services are used to transfer money home at much cheaper rates than possible with banks or financial service brokers. Overall PC penetration in the Middle East is very low, less than 20%.
Inveneo's Kristin Peterson described their observations from their efforts in Africa. Inveneo is an unusual startup - a nonprofit social enterprise aimed at connecting villages around the world. In many of these countries, communication can make dramatic differences in the lives of people in villages. However, most of them cannot afford expensive solutions. So, state of the art technology is mostly available as a shared resource. Even what we take for granted and available cheaply at Fry's in Silicon Valley may cost several times more by the time it makes it to a remote part of Africa. However, the effect of small things such as being able to communicate with a market in a neighboring village to find out that the price of crop is higher there may make a considerable difference to a poor farmer trying to sell his produce. He may be willing to travel the extra miles necessary to get the price differential.
While at the event, I met Hans Robertson of Meraki, a startup with the lofty goal of bringing Internet access to the next billion people. Their idea is to have small low cost wireless devices which can be added incrementally to form a mesh network. While the idea of mesh networks itself is not new, their take is on the ease of use and low cost of deployment. So, someone with access to the Internet could quickly deploy a wireless network and provide access to those who don't. Though, I am sure the service providers would want a cut of it, there is still room for enterprising entrepreneurs in developing markets to create small businesses and be the local ISP ;-)
While we in the Valley are in a race to provide the latest in technology, the rest of the world, especially the villages, are struggling to improve their lives with what technology they can lay their hands on. To them technology is not an end in itself, but a crucial means for improving their lives. Clearly the rate of adoption of technology is much slower at the fringes than at the center of the vortex of technology. :-)

MIT Club event on Energy Storage
In the pursuit of alternative energy solutions we don't often hear about energy storage. Interestingly, for the public utilities like PG&E and for alternative energy providers it is a very important issue. In the US we rarely have load shedding or blackouts, but in countries like India where this is common homeowners are very used to backup power supplies, mostly made up of lead-acid batteries. This is indeed a common and cheap storage mechanism as the panelists pointed out. The target for storage technologies is $150/kWh and currently most of them are 2-5x the target. Dr. Mills talked about Ausra's Concentrating Solar Power, which uses solar power stored as superheated steam and recovered using steam turbines. He claims over 95% efficiencies for the storage part. However, the technology requires a lot of area and is targeted at medium to large installations, O(MWatts), and not for residential or portable storage. The interesting technologies which are suitable for residential customers are lead-acid mentioned earlier and Lithium ion batteries. Yes, the same battery technology used in laptops and MP3 players. Due to mass manufacturing planned for this technology to address consumer markets, this will be a viable energy storage mechanism for larger applications, approaching $250/kwH in cost.
Mike Gravely talked about research programs funded by the State of California on renewable energy projects. This is the State of California's effort to encourage the development of renewable energy. It is seed money available to businesses and individuals to develop their ideas in the space. The grants are awarded every 4 months based on proposals received. The process appears easier than trying to get seed money from angel investors, if you have a good idea. Its only fitting that the State of California encourage innovation as an angel investor :-)

Al Gore and Democratization of Technology
He spoke about the difference between flying on Air Force 2 and having to take off his shoes when he boarded a plane these days. He also talked a fair bit about technology, global warming, outsourcing and the short term point of view which we seem to be adopting in the US these days. He compared our generation to the "Greatest Generation" which returned from saving the world from fascism and helped reach out and rebuild the enemy with a moral authority, so that there was greater wealth and stability all around. He described a vision where we had the opportunity today to use technology and policy to solve the world's very real global warming problems and create wealth and jobs. Where we saw a crisis today, he pointed out that it presented both danger and opportunity. He pointed out that seizing this opportunity would require taking a longer term point of view and relying on a moral compass.
Just judging from this one speech, I am pretty sure he would win the election this time around if he chose to run, though I am not sure Hillary Clinton or the Republicans would be too happy about it. Of course, if he wanted a sympathetic audience, there's nothing to beat a Valley crowd. Which might explain why he keeps talking at all these Valley events :-) However, I do believe that he may have a tougher time convincing the larger US population on the moral compass and longer term points of view. The world seems to have changed much in fifty years and the idealism of the '50s and '60s, seems to have dimmed a bit. But, who knows, Al Gore may just be the man to reignite it. He certainly seems to glow with a new found passion and vision.
