electric cars

[mrmod]

I think time is needed. There's no point hoping that we will have e-cars en masse by the end of the week. At the end of the decade seems like a much more realistic take. And this is just to develop technologies...

And batteries are complicated. Many use expensive metals (hence recycling can help) and using an acid is generally required (as an electrolyte if im not mistaken). And you need a battery that can make a strong current. Safe is not how I'd describe a battery.
