Could low level, pulsed electrolysis of water be
overunity?
There have been some reports of this happening -
although they have been attributed to measurement errors by skeptics.
Suppose that, at any given instant, a few, random
water molecules are ready to split apart. They would be momentarily
vunerable
to a pulse splitting them apart - that would contain
less energy than is normally required to achieve electrolysis.
There is a patent by Puharich that discusses Gibbs
free energy and the addition of temperature as increasing the efficiency
of splitting
water molecules. There was also a fellow named
Kanarev who claimed to achieve an overunity electrolysis by this means.
