Delbert, You can NOT get something for nothing. Energy has to come from somewhere. Hydrogen was never said to be a source of energy. It is a carrier for storing energy. Actually the way the argument was presented on this tread, it was characterized that hydrogen is out there for the taking. Here it is one more time, I do not know of any free sources of hydrogen gas on planet earth. Right now hydrogen is made commerically form natural gas, which does not solve our ME problem. If one makes hydrogen from water as was shown in the BMW link, you will need a tremendous amount of electricity. Again you can't get something for nothing. That electricity in turn must be made from some other fuel (coal, oil, gas, nuclear). At the the present time solar just does not cut it to produce the amount of electricity required as shown in the BMW link. Your "commitment" does not change the laws of physics. Do you ridicule and not use cordless drills and cell phones? The battery in them is not a source of energy either. That rechargeable cordless drill that I have uses electricity. In Maryland, where I live, 80% of electricity is generated using coal. Hence coal is the SOURCE of energy for my drill. If I have a primary battery the energy comes from the chemicals. Those chemicals in turn must be MADE using processes that in itself requires more energy than is present in those chemicals. Gasoline also takes energy to produce and does not occur naturally. No. Gasoline is made from distilling crude oil. Hence the term "crude". The distillation process uses a negligible amount energy relative to the energy content of crude oil & gasoline. Your windmills and solar panels will need at least and EQUAL amount of per unit of energy as that in hydrogen. In practice you'll need even more energy because of inefficiencies in production and transportation. BTW, the latest thinking is that there may be a huge amount of uncombined hydrogen down a few miles. Show me...
