-----Original Message----- From: Robert McKay A gallium aluminum reaction might also be a good way to go;

Plus, as mentioned in another post, when a fraction of the HHO is combusted, that heat (and light) can supply the threshold energy input which is needed in the Rossi reaction. At least with the HHO cell for supplying hydrogen - the input power can be read with a meter - so there is no doubt how much is going in. These cells are fairly efficient 70-75% so to reach a net level of overunity, the gainful Ni-H reaction, which happens for that fraction of hydrogen which is not burned initially, probably needs to be COP~2, but according to AR: no problemo... oops make that: nessun problema.
