And, please, tell me how you are going to produce hydrogen in sufficient purity and quantity to run a relatively low-efficiency device like a fuel cell? AND ensure that there is no pollution in the process? The much-vaunted fuel cell for, e.g., large-scale car use can never be. It is being developed purely as a magnet for governmental funding. If you wish to discuss this in more detail, I propose we shift the debate to the EnviroNet. I never proposed mixing the H2 and O2 to produce BANG. There are a number of ways of non-explosively combining the two gases safely, the simplest being a straightforward hydrogen flame.
