I don't think it's possible to please some Green types with

Once H2 fueled vehicles come on line in perhaps 10-15 years,
their by-product of combustion will be water vapor.

Water vapor is much more effective "greenhouse gas" than
CO2.

But the atmosphere can only hold so much water vapor before it falls out of
the sky as potential fuel; rain. Water vapor will probably not effect
greenhouse problems very much.

So donquijote1954 is just showing off how little he knows about what is
happening in the world.
