Not enough feedstock in the world, make it methanol now we can talk.
Make the fuel stock methane, then we have a viable concept.
Methane exists as a distinct and relatively pure compound in many places and from many sources, and while one molecule of carbon dioxide is produced for each two molecules of water, the production of carbon dioxide in and of itself is not a bad thing. In fact, that is an essential part of life.
But there is a HUGE reeducation program that must be introduced to reverse this flow of misinformation and downright lying. Then, finally, the advance of REAL science may begin anew.
