here's a company doing it with grants not real profits yet but just maybe.
Elk River sophomore Josh Wolf has a lofty goal -- helping to solve the world's fuel crisis -- using a humble tool: algae.
In the portable garage that serves as a back-yard laboratory, he has discovered that the application of a very low-level electrical jolt causes algae to release oil. After a couple of days, he skims it out, adds a formula of plumbing cleaner and antifreeze, and presto, it's biodiesel fuel. The fruits of his labors could be traveling around Elk River on any given day in the diesel tanks of friends' pickup trucks.

One of the best uses is as a food source. Algae alone can sustain the human body for years.
