“Algae yields have not yet been accurately determined, but DOE is 
reported as saying that algae yield 30 times more energy per acre than 
land crops such as soybeans, and some estimate even higher yields up to 
15000 gpa”

I read statements such as the above with increasing scepticism. Does 
anyone have verifiable figures  (in tons per acre per year) of biomass 
for algae such as Chlorella or Spirulina ?

Many thanks
