Electric vehicles were in wide use in the early 20th Century, mostly for 
commercial vans. Then as now the batteries take up too much space, weight
too 
much and are too short-lived for the elctric vehicle to be a viable 
alternative to the internal combusion engine. Period. The thermodynamics
are 
unyielding. The hydrogen vehicle is an internal combustion driven vehicle.
It 
is not economic in any real world contest because the fuel costs too much
to 
produce, too much to trans****t and too much to store. A gallon of gasoline
or 
diesel or peanut oil weighs 7 to 8 pounds, for the sake of argument. It
will 
get you twenty miles in a heavy vehicle, these days over forty in a well 
designed one. To get the same range with hydrogen you have to carry the
same 
weight of fuel. How much pressure does it take to compress seven pounds of

hydrogen into the space of one gallon? You sure you want to be riding
around 
with that bomb at your back?

Some years ago there was a ig push for steam cars. They did exist, once.
They 
are not efficient (external combustion) and who wants to be scalded by
high 
pressure steam in the event of an accident? We don't hear much about steam

cars anymore.
