Wow. Recycle the CO2 back into fuel. Now that would be some green tech. But what was the one part about a poison side effect? Was he talking about poison messing up the process or poison as a side effect? I think he means the former, because if recycling CO2 would mean pumping poison into the atmosphere instead, this would be the worst project ever. X'D
But damn, recycling CO2 would actually be pretty huge.
