Hydrogen right in the air, combined to take advantage of environmental
conditions, can be used to extract hydrogen gas straight from the air,
and use it as a highly explosive source of gas compatible with the
power of gasoline, but without the pollution effects. Hydrogen gas can
be used to produce electricity, heat the RV, and run the RV's engine
with the usual engine sound of gasoline engines.

The solution to extract hydrogen on the go from water is possible,
the idea is to move above 100 percent energy efficiency with a
combination of technologies. A combination of fuel cell (for
electricty) and a high power hydrogen combustion engine might
produce unexpected results in free energy. Also water can be
extracted from the air using electricity by compressing warm (heated)
air. Upon an experiment I found that during hot summer days the
air conditioner is producing a lot of water waste in dry Colorado
merely from compressing hot air.
