The website really glosses over the part where they turn alcohols into gasoline. Is this an existing technology that is already available? I dont know as I'm not really plugged into energy generation technology. Also, it says that Titan turns 9 millions kilotons of CO2 into 1 million gallons of gasoline. Does it actually do this or is that what they expect it to do?
