You're a real gem, Eclipse Now, Thanks for the info.
I must admit that currently an agenda pusher, and will not rest till I compile all the problems and their solutions relating to ethanol as a dominating fuel.
I'll be more open a little later, however. (After I've either finished with ethanol's list or hit upon insurmountable obstacles. And given my presentation at my univ.)
Anyway, I note that:-
1.
algae may prove to be an excellent source of cellulose (or biomass for ethanol production)
The advantages of being grown in the water are simply too brilliant. They might reduce the stress on land quite significantly.
Unformed thoughts have begun to grow in my mind about offshore cordoned off areas where algae could be grown. (Did I let that out?

I need to patent it fast!)
2.
The supply channels of ethanol will not be as simple as I assumed it would be. A method to simplify the transport needs to be devised. Say- anti corrosion coatings especially for ethanol? Need some googling around.
I cant wait to get started; damn the assignments I'm wading through!
