This has been known from the earliest days of chemistry. The snag is the
amount of energy required to produce the hydrogen. If you were to use
petrol, etc, to produce the hydrogen, it would be far more efficient to
burn that petrol directly in the car engine.

Or since much electricity is produced by burning gas, to compress that gas
into LPG and burn that directly in the car.

It only becomes viable where electricity is produced in abundance by
'free' renewables, like wind, water or solar.

ITYM inbcedribly expensive renewables:-)


Sadly, you don't get owt for nowt in this world - despite what vested
interests would like you to think.

If it costs nowt, chances are its something no one wants anyway.

(in-ep-toc-ra-cy) €“ a system of government where the least capable to
lead are elected by the least capable of producing, and where the
members of society least likely to sustain themselves or succeed, are
rewarded with goods and services paid for by the confiscated wealth of a
diminishing number of producers.
