Reply to "Electric Cars - Saviours of our environment or just another fad?"

One proposal a few years ago was batteries mounted on the car's underside, and 'refuelling' achieved by physical battery exchange - park the car in the designated spot and it would be done mechanically from below in minutes  - all based on batteries not actually being owned by the car owner, rather rented or leased, I suppose a bit like cylinder rental of pressurised gas cylinders.
