Robert,
you responded to an earlier posting I made regarding recycling effluent with a couple of URLs that could be valuable to my search for oil recovery programs. I seem to have lost them, could you please send them again?

Mr. Benson,
here is what I see in Wikipedia regarding jatropha,
"Goldman Sachs recently cited Jatropha curcas as one of the best candidates for future biodiesel production.[4]However, despite its abundance and use as an oil and reclamation plant, none of the Jatropha species has been properly domesticated and, as a result, its productivity is variable, and the long-term impact of its large-scale use on soil quality and the environment is unknown.[5] However, because jatropha can grow in harsh climates, it can be planted in areas where it won't compete for resources needed to grow food.[6]"the emphasis is my own.

How about than Jatropha? And more crucially (at least to me just now) how much faster will algae grow using ordinary CO2 levels? I've seen claims of 20x, even 30x, but these must be at enhanced levels of CO2, yes?
