This looks interesting. It should be in the hybrid section of this website. Could you explain a few details? I see that you have a water filter modified to act as a fuel cell. I don't see the electrodes or stacked plates inside of it. Where is the high voltage coil (or are you using one which is connected to your vehicle)? Are you going to connect the hose to the fuel port to run the engine on hydrogen? Would it supply enough hydrogen on demand without a storage tank? About 1 1/2 years ago I connected my fuel port to a propane cylinder, but the engine wouldn't work properly. I had to start on gasoline, then switch over to propane. It wouldn't rev above idle on propane. It could only run for about 10 seconds before cutting out.
