Machine Design – March 3, 2009: "To avoid the need for ponds spanning thousands of acres, OriginOil grows algae in a bioreactor. Bioreactors have an advantage over Mother Nature in that they can stimulate growth of algae 24/7, not just when the sun shines. Moreover, it's possible to mix up the algae in a bioreactor so all of it gets hit with light, nutrients, and CO2. That's not the case on a pond surface where only the top half-inch of algae can grow."
