Total nonsense!! There have been numerous "water as fuel" schemes promoted lately but they're all about as worthless as whale doo-doo. All
this schemes are based on using electrolysis to generate "Brown's Gas"
which is simply the oxygen and hydrogen mixed together after water
moloecules are broken down by electrolysis. The Brown's Gas is then
simply used in an automotive engine like propane or natural gas are by
the use of a mixing valve to meter the gas into the induction stream of
the engine. Hydrogen is better viewed as an energy transfer medium than
an energy source of and in itself since it takes considerable energy to
extract it from water molecules. Hydrogen can certainly be used as a
motor vehicle fuel but apart from the energy necessary to generate it
from water, the other problem is storing sufficient quantities of it in a
motor vehicle to give the vehicle a reasonable range. Most systems
in use these days either use compressed gaseous hydrogen at very high pressure (300 bar or more) or cryogenic storage where the hydrogen is stored
in liquid form in insulated dewars.
The "water as fuel" scheme promoters would have you think that their
contraptions can electrolize sufficient quantities of water into hydrogen
"on the fly" to make either high pressure or cryogenic storage unnecessary,
but if this was the case why is it that only SPAMmers and backyard crackpots
are promoting it!
