The process of getting an excess heat reaction will happen
as the water connects to the nickel or palladium metal.
When the water makes that connection the reaction happens.
When the reaction happens, excess heat is generated.
To have excess heat is to have more heat coming
out of the system than what was originally put into it.
This excess heat created is useful because
it is capable of making hot water or steam.
Steam could turn turbines which is when the electricity is made.
