electric cars

[. . . .]

the bad thing about electric at the moment would be where to put all the used up batteries and we still burn fossil fuels to charge them up.

hydrogen as such leaves a footprint which is so much smaller.
maybe in 100 or 200 yrs from now battery cars and any other will be laughed at and we'll all drive on mag lev roads. using the smallest amount of energy to propel us.

Good point; when the batteries do need replacing they will most likely be done by a certified mechanic who should have to give them back to the company for recycle.
