I think the final piece of this puzzle is going to have electrified highways so you can travel long distances without the need for large battery packs. It would still be more efficient to uses busses/trains but we already have a lot of roads and cars which make retrofitting seem like the best option.
- liotier 15y agoYes - and we could replace the rubber/tarmac interface with a steel/steel one for even better efficiency. Highly automated steel-wheeled vehicle on steel tracks with continuous electricity supply along the way... I wonder how we'll call that.
- ebiester 15y agoSo long as I don't have to walk a mile to get to the steel/steel in the 110+(F) sun, I don't care what you call it. ;)
- jules 15y agoWhen we got a talk from a renewable energy / car battery researcher at my university at the end of the talk I asked him "don't you think that given the costs and difficulties with scarce materials that it would be cheaper and more energy efficient to create power lines for cars on every road than to put a battery in every car?" -- and he agreed, except that this strategy doesn't have a good business model unless governments take major steps.
- rationalbeaver 15y agoSeems like it would be a pretty good business model for utility companies.
