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
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 ?
