Yes, of course, I know about entropy, but the point is to move away from oil dependence because no matter how you see it, that dependence is destroying the planet.
OK, I can't afford to buy a hybride car or a car that works on ethanol only, for the moment, but I
could drive on 20% E85 and 80% 95 octane gasoline, which would help the environment at least a bit, but I won't do it unless they lower the price on E85, so that it also becomes economically reasonable to drive on 20% E85.
You don't have to like it, but you do have to get used to it.
