Now if can just find that elusive budwieser tree, I'll be all set;)

It's not a whole lot of fuel, but by the simple fact it requires no refining or processing, makes it an extremely efficient energy source.

I've read that a few companies in North America and Europe have been refining this type of product. Several US and European Universities are devoting research to it as well (even Boeing and the Big 3 Auto Manufactureers have time and money going towards research).

I would assume it is the very thing the "home brewer" should be looking into before the big energy corparations dominate the market and science. Most of us do not have acres to devote to terrestrial crop--but, a few big vats in the basement, that's another matter.... The science behind it seems approachable for the common man.

I saw a cool experiment on TV recently. They took some of the CO2 from a natural gas power plant in the Southwest somewhere, and bubbled it up through some glass tubes full of water and algae. The algae sequestered (sp?) the CO2, and they can use the gloop for biofuels, etc. It looked pretty neat.

Then they explained that to capture all the CO2 from that plant, they'd have to have like 20 square miles of these algae thingies, lol.

I tried to find something with pictures, to no avail. But here's an article about it:

Here's a company doing it: http://www.greenfuelonline.com/index.html

Here it is! This looks like the thingy I saw on TV: http://www.msnbc.msn.com/id/15287313/
