Vinod Khosla has found a company that harvests excess heat from solar collectors and improves their total energy output by 50-100%, a huge gain that makes even regular panels financially viable.

Scientists at MIT have unveiled what many consider to be the Holy Grail of alternative energy research. They have discovered a simple and inexpensive way to store the energy generated from solar systems. Storage is critical because it solves the night/clouds problem and the battery problem. Their method splits water into hydrogen and oxygen using the electricity generated by the solar source. The hydrogen can be stored and used in fuel cells for virtually any kind of power generation. Until now cracking hydrogen from water has cost more in power than the energy value of the hydrogen. Now, with this system, which the inventors claim is only a few years away from commercial viability, we could have an inexhaustible source of clean energy that can be used anywhere, at any time. It should be noted that the only byproduct of using hydrogen fuel cells is pure water.

While time will tell whether this is the huge breakthrough it appears to be, the reception among informed scientists and engineers is more positive than we usually see when someone makes these kinds of claims.

For me the really interesting local angle of this story is that this research was funded by a ten million dollar donation from a foundation created by Rochester entrepreneur Arunis Chaesonis, founder of Paetec, a very successful telecom based here. Wouldn’t it be great if a breakthrough energy story came out of innovative thinking in Rochester?

One other thing: GM has long had their fuel cell hydrogen car project based in Rochester at a skunkworks operation in Honeoye Falls. The only thing holding back their technology has been a lack of efficient hydrogen production and delivery infrastructure. So this is a double win for Rochester.

I can either commute via the expressway or by taking a four lane road (East Ave) that makes its way through mostly residential neighborhoods into the downtown area where I live. It wouldn’t be a bad bike route except the fact that it has four lanes means a cyclist forces traffic in their lane to move into the left lane to pass the bike.

There is no reason to have four lanes on this road. If we took one lane and split it to make a bike lane on each side and then created a center turning lane we’d lose no driving convenience whatsoever. This would essentially only involve restriping the road to the new configuration.

Our city is criss-crossed with these four lane, 35mph arteries. A county-wide plan to create bike lanes would help change a lot of perceptions about bike commutes. We could even use them as scooter lanes for low-powered scooters with a low speed limit (20mph?).

With our winters I know there are skeptics about bike commuting. However those winters are getting shorter and fall and spring are great cycling weather periods. Competition with cars is a major factor when considering a commute. Dedicated lanes would help. They would also keep people riding on the correct side of the road (with the traffic). Riding against traffic or on sidewalks is a major safety issue because drivers don’t expect anything there.

The idea that we should cut federal taxes on gas for the summer is an appallingly cynical, politically motivated panacea only two candidates for President could cook up. Do they really think Americans won’t recognize this for what it is: A cheesy handout to warm up voters?

Read Tom Friedman on this:

“The McCain-Clinton gas holiday proposal is a perfect example of what energy expert Peter Schwartz of Global Business Network describes as the true American energy policy today: “Maximize demand, minimize supply and buy the rest from the people who hate us the most.”

Few Americans know it, but for almost a year now, Congress has been bickering over whether and how to renew the investment tax credit to stimulate investment in solar energy and the production tax credit to encourage investment in wind energy. The bickering has been so poisonous that when Congress passed the 2007 energy bill last December, it failed to extend any stimulus for wind and solar energy production. Oil and gas kept all their credits, but those for wind and solar have been left to expire this December. I am not making this up. At a time when we should be throwing everything into clean power innovation, we are squabbling over pennies.”
