Now that's solar energy in action. Hmmm, according to
this, the costs of growing algae as a fuel is comparable to Gasoline at $4.35/gallon.
I wonder how you could sequestor that carbon? Heat it without O2 and make algae-charcoal?
Update: Some of the Cyanobacterias double every few hours (take that pond scum!), and it's been tested for
CO2 removal
