Bio-fuels *are* a great idea.

Until you realize *how much* gasoline & diesel this country uses
(then add 3x more to that for the rest of the world), and the fact
that stuff like corn ethanol needs lots of (*petrolem* based)
fertilizer.

(However, sugar cane ethanol in Brazil is a *great* idea, because of
cane's higher sugar density, Brazil's proximity to the equator and
lower population).

Based on things I have researched and processing systems I have seen and
actually went through the motions of getting the nitty-gritty on.

Algae based Bio-Diesel. 110,000 square miles of "useless desert" flooded
with salt water and seeded with a certain algae... would supply enough
Biofuel for all vehicles (provided all current vehicles were converted
to diesel) in the US with about a 25% energy return on energy used to
process it and transport to filling centers.

there is an algae that supposedly has something like 80% "oil" content
as that is what makes it float. is this the same stuff?
