Comment You can get food from algae (Score 1) 90
Whenever algae comes up I like to cite a noted expert from the area for 50 years:
Benneman
Look the main problem with algae is that it is really a new form of agriculture. And everything people tout as an advantage cuts the other way. At best it is carbon neutral. Now tell me how many desert ponds are located by a source of CO2?
Don't get me wrong, I think Solazyme has nailed it, there are a lot of great things we can do with algae. It can be a food for example; chemical feedstock.
As a fuel...for the infrastructure of ruining vast desert landscapes we'd do far better pumping coal gas CO2 back into salt mines.
