[Gasification] Gasification and Water Injection into producergas

[Jesse Klinkhamer]

Algae is an extremely interesting development for biofuels. It produces 6
times that of corn and requires far less resources and should be considered
a viable option...in my opinion!

But then what do I know!lol

I t makes sense that we would not want to complete the oxidation  
process without a way to scrub out the CO2 later.

It seems that one beneficial way to complete the cycle, instead of  
scrubbing CO2 after complete oxidation could be to use algae
as a tool for releasing the O2 and recovering the C into a feedstock  
for biodiesel.

Does this make sense?  I think this company (PetroSun subsidiary  
Algae BioFuels) and the concept of algae to biofuels looks very  
promising.
