Readers of a several blogs which attack the production of biofuels (read,ethanol) will recognize that the authors are not tuned into biodiesel based on algal oil. Here is my response:

Hoax readers:

I sure wish you folks would study growing algal for food and fuel before you expend time kicking a dead horse. Spirulina offers 75% protein and Chlorella offers up to 50% lipids from which biodiesel can be made. Ponds can be built on an asphalt parking lot or on rocks (not recommended) or put on marginal and highly sodic lands. NREL spent $25 million and 20 years proving that algae can be grown and can be used for algal oil for biodiesel.
