Not necessarily all to do with Physics anymore....think beyond the 20th
century. I believe it will happen one day, give it 20/30 years and it will
be all the go. Better batteries/alternators/electric engines and more than
likely, powerplants we can't even imagine today. Open up your mind and be
prepared to venture beyond the square. Who would have thought 100 years ago,
we'd have television 50 years later or mobile phones with video
conferencing. There would have been rules back then to say it couldn't be
done.

Also correct toby ...which is why you can still receive a 30,000volt from an
old television yoke that's been "dead" for 6 months or more.

They don't need to invent perpetual motion for electric vehicles to
become a viable alternative to a petrol/diesel vehicles, what they need
to do is improve efficiency so that an electric car has a usable range
of around 400klm+ and can be fully recharged in about 30mins.
When that happens electric cars may be useful for other than short city
commuting.

Use alternators to recharge the batteries
