Ecat is a nickel reactor it converts nickel/hydrogen (Ni/H) to steam cheaply with no radiation. Ecat is a small nuclear reactor that can be used in the home to produce steam for heating, hot water, and electric generation. http://en.wikipedia.org/wiki/Energy Catalyzer A model Ecat system is shown that can be improved with laser spark plug, cella hydrogen fuel inputs, TEG energy recovery, and Rankine organic system. Examples uses of Ecat in a hot water heater and a Rankine electric car are shown.
