hydrogen production

"The United Nuclear Hydrogen Fuel System Kit converts your existing vehicle to run on Hydrogen.(...) Included in the kits (and also available separately) is our solar powered Hydrogen Generator that manufactures the Hydrogen fuel for your vehicle at virtually zero cost.(...) Since there are no major changes made to your engine, you can still run your vehicle on Gasoline at any time.
We now have over 50,000 trouble-free miles on our prototype vehicles. (...)

A unique system that can produce Hydrogen inside a car using common metals such as Magnesium and Aluminum was developed by an Israeli company. The system solves all of the obstacles associated with the manufacturing, transporting and storing of hydrogen to be used in cars. When it becomes commercial in a few years time, the system will be incorporated into cars that will cost about the same as existing conventional cars to run, and will be completely emission free.

Solar Hydrogen Energy Corporation has demonstrated that solar energy can be concentrated to over 1500°F and used to produce Hydrogen.
