Do you really think it an efficient use of energy to convert water to
hydrogen then burn in an IC engine?


But we'll have this vast surplus of green energy, with all these
windmills and solar panels, won't we? The phrase 'too cheap to meter'
comes to mind. ;-)


Then use it to charge an electric car. ;-)


simpler to change the carburetor on an existing vehicle. Our workshop
technician did that to his car during the petrol rationing of 1973,
and ran his car on propane. SU carb, IIRC; he just bored out the jet
and machined a fatter needle, although I doubt that modern carbs are
that simple to DIY modify, but modified carbs would be available
commercially.


Carbs? Wake up grandad. ;-)

Seriously, hydrogen is very different to propane or LPG in its combustion
characteristics. This renders it very unsuited to use in an IC engine.
