I can't comment on this technical process, but a general problem with convert (a -> b) is the amount of energy required. There will be good results from many processes (butanol, some ethanol, etc) but none are gonna be the single magic bullet that replaces all petro sources. It's safe to say, conservative even, that there will never, ever, in our thinkable human history, be one "fuel source" that does so many things as petroleum did. We might as weill just get over it now. This "fuel" idea has got to go. I know I sound like a broken record (CD?) but other than "recovering" what is previously stored from the long past (oil) or wasted (eg. the energy dissipated as heat in brakes should be stored for later use instead) there is only energy STORAGE or TRANSPORT. It's gotta come from somewhere! Oil (coal, NG, etc) is old energy, and with it's release comes Stuff (carbon, etc). That's "fuel" in the sense that someone else did the work long ago, we're just pumping it and burning it. Nuclear fission is also "fuel" in that sense of the work to make the big atoms was done long ago, and we crack 'em to release the energy within. There's side effects there too that would probably be tolerable if you kept cheapskate corporate-growth bean counters from making decisions on how to run it. Other than that, I can't think of a single "fuel" in all of the earth. The smart, but hard to do, and "not cost effective" to people who wanna profit quarter to quarter (reality? time to change that "reality"), is to use the energy that just literally drops on the ground, a few kilowatts per square yard, about half the day. That, plus consume less, which really just means stop wasting, and zillions of niche solutions, instead of this 19th century idea of one solution for all problems. _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list
