I also see where WhiteD3 is coming from ;
using
H2 to augment combustion in an ICE ( Internal Combustion Engine ) That technology is
plausible ; and it works , people have installed them and are seeing the Benifits ;
Like Dave Blknight said earlier , it's like having an LPG infumigation system on a Diesel.
but a claim that ICE can run on purely on water alone,
as has already been said it requires an enourmous amount of
energy to seperate the Hydrogen and Oxyn Molecules to utilise the H2 in an ICE
