No I'm all for it. Bring it on. Fuel Cells would be great if it was viable to split water molecules and turn them back to water. I warn you though that the round trip process is energy inefficient. The process to produce the hydrogen from water is not likely to yield a cost benefit over fossil fuels for a long time. One statement that you posted said they were at an 8.5% efficiency for doing this, that means 91.5% of the energy is lost usually in the form of heat. Once converted a fuel cell will yield less than 40% efficiency and could be as low as 24%. A car engine yields about 20% efficiency How long do we wait? What do we do in the meantime? Jim
