[ausev] Where the energy comes from, was: Electric energy transfer and storage limitations

[John Rumsey]

EV's all require electricity to recharge the
batteries, that is their one source of energy. Since
few people would have their own electric power
sources, they either plug into the grid or sit until
the grid comes back on after a disaster. It does not
matter how the electricity is made for the grid, what
the ultimate source of the electricity is. EV's are
dependent on the grid. My thought was to have a small
steam powered generator in every electric car built
for long range use so you could drive without the grid
and even provide emergency power for your home. Why
buy multiple cars and an emergency generator when it
could all be in one package?
