Electric cars will not cut emissions. When batteries are being charged they
give off an explosive vapour. This also contains particles of the battery
which is very harmful. The green people should look at the complete scene
not just a little part which seems to suit them. Try visiting a place where
they have a fleet of electric vehicles and visit the battery charging shop.
If we do go over to electric vehicles a lot of people will get killed or
injured because people don't hear them coming. I know that from working at
Gatwick where they had a large fleet although that was years ago. Do not
forget all the factories that will be needed to make these motive power
batteries and then all the extra power stations and how will they be
powered?
Also people pushing for hydrogen power should be made to watch the film of
the Hindenburg disaster.


Modern batteries are sealed systems, its the "conventional" lead-acid
batteries that generate hydrogen when charging.

The rest of your points are valid.
