[Gasification] Gasification and Water Injection into producergas

[Kevin Chisholm]

Dear Jesse and/or Peter

Very interesting!!

As I understand it, some algae can contain as much as about 30% fats. 
However, it costs a lot to recover and dry the algae.

Would you have some approximate idea of the cost of biodiesel produced from 
algae?

Best wishes,

Kevin
