Amnon Yogev, an retired Israeli professor from the Weizmann Institute and one of two founders of Engineuity, has invented a car that produces its own hydrogen fuel from light metals, such as magnesium or aluminum, eliminating all of the infrastructure required for making, transporting and storing hydrogen. The inventor claims that when the cars become commercial, they will cost about the same as conventional cars and will be emission free.

A coil of the fuel - aluminum or magnesium - is fed into a device called a Metal-Steam combustor that will separate hydrogen out of water that is heated to a very high temperature.
