Wind. Put the necessary equipment at the base of every wind turbine,
there are enough out there. No energy waste at all.

Yes, of course fuel cells need replacing, but so do batteries, and fuel
cells are a lot lighter. Plus the car doesn't need refuelling any more
frequently than the equivalent petrol/diesel car. Battery electrics need
charging far too frequently and if you don't live in a property with
your own driveway or garage, where do you charge it..?

What about on a long journey..? Are you going to sit in a queue for a
charger at a motorway services for three hours while several people in
front of you take a minimum of half an hour to charge up..?
