Top 20 Green Tech Ideas – Algae Food

You may have to look hard, but some very smart companies are doing some very creative things when it comes to the environment

For something that looks like pond scum — actually, it pretty much is pond scum — algae are extremely useful. Just ask the San Francisco startup Solazyme. Like countless other companies, Solazyme is working to create algae biofuel for cars, trucks and planes. Unfortunately, that market has yet to materialize, and because fuel is such a low-margin business, companies like Solazyme will need to sell a lot of their product before they can begin making a profit. It’s classic chicken-and-egg economics.

But Solazyme’s chemists stumbled on another use for their algae: food. The company’s living products can be used to make flour, which can replace conventional flour in cakes, cookies and more — except that the algae flour has a lipid profile that is much closer to healthy olive oil.
