Is Algae The Biofuel Answer?

Algae are capable of generating 33,000 gallons of oil per acre per year (while corn can produce a mere 30), but how is this kind of oil best produced? Valcent Products Inc. has patented the VertiGro system, which grows large amounts of algae in a vertical system of panels that increase surface area and light exposure, thus increasing oil yield from algae.
