QuoteBe excited, Earthlings, because science has a surprise for you. Engineers at the Department of Energy's Pacific Northwest National Laboratory have devised a way to turn algae into crude oil in less than an hour. That oil can then be refined into gasoline that can run engines.
Excited yet? Try wrapping your head around the implications of a breakthrough like this. As one of the most plentiful lifeforms on the planet, algae is a perfect candidate for conversion to biofuel. It's especially good because the energy is packed pretty tightly into that green sludge. To replace all of the petroleum in the United States with algae fuel, you'd need a farm that took up just 0.42 percent of the country's landmass. By comparison, it would take up half of the United States to grow enough soybeans to replace petroleum with biodiesel.

Not the ever elusive so-called "free energy" - but a big step forward under cutting Big Oil. Entirely sustaineable, very cheap.
