Brilliant. Instead of changing infrastructure to accommodate ethanol or bio-diesel, why not change the fuel?

Sapphire Energy plans to use Algae to produce Gasoline.

Simple, and smart. These are the kind of things that could really be game changing.

Earth2tech.com has a good review of cellulosic plants that are being built. I personally hold great hope for cellulosic ethanol as being a very promising technology for the future. Let's keep out fingers crossed.

This report includes plans, and some interesting notes on where the funding has come from.

Since 1981, the top selling car in the US has not been a car, but a truck. The Ford F150 has consistently been the top selling vehicle. In May, in a remarkable change, the Honda Civic has jumped to the top of the list.

Is this a sea change? Or a temporary bump? Clearly fuel prices are high, and that leads to changes in behavior, but will it extend to support for other greener choices?

If someone can produce ethanol for $1 a gallon, as has been claimed, will small efficient cars remain popular, or will we instantly see a return to big trucks and SUV's?
