  A very interesting topic. Both Hydrogen Safety and UCSB Science Line having the ability to burn. So IMO, you've to separate the oxygen and hydrogen from the water and burnt them alone?

  It takes energy to break the bonds of H and O in water. You get this back when you burn them. Unfortunately the processes are not 100% efficient. Burning H2 in an engine has losses with friction, heat, etc. Separation of water into H and O also has losses. Even for fuel cells. I think you may as well charge batteries. Storing enough Hydrogen to run a car is not as safe yet. Many companies and people are working on it. TI was working on a Solar panel that separated water into Hydrogen and Oxygen a few years ago. I never heard how this turned out. The process/patents were probably purchased by a large oil company and sites in a vault for now.

  Well, steam engines have been around a very long time. What else do you propose when you want to use "water as fuel"?
