hydrogen.

Toyota never bought into BEVs and favored hybrids. The Mirai is impressive
but it points out the problem at this time.

Hydrogen will need a real PR campaign. A company I worked for had a
contract to produce the glass tubes for strobe lights. It was a glass
blowing operation to form the corkscrew shape. Soda glass can be worked
with oxy-acetylene but quartz glass needs a oxy-hydrogen flame. We had to
get a permit to have a hydrogen tube trailer spotted on the premises
despite hydrogen being safer than acetylene. I could see the fire marshall
thinking 'bomb' when we said 'hydrogen'.

The tanks have improved. In the '70s the weight of hydrogen in a tube
trailer was ridiculously small compared to the wieght of the trailer. New
materials reduce the tank weights and the DOT has increased the allowable
pressure but it's still a transportation problem.

Then there is the problem that most hydrogen comes from processing natural
gas rather than green alternative energy sources.
