Re: Batteries in cars

I assume you mean 34 kWhr. That's about five pounds-worth of electricity and looking at Powerwall prices you'll be paying something like ten or fifteen thousand pounds for an installation with a twenty-year life, which seems -- high.

But even if you fit that battery, the only way you can be running a house in winter on five kWhr per day is by a) freezing or b) not being in it, or c) heating it by burning something -- gas/oil/logs/peat/furniture. You certainly won't be charging your car from that battery.

Electric cars are great, part of the solution, and electrification of everything -- with its easy interchangeability of primary sources -- is the way to go. But the focus then has to be low-carbon primary energy with power for to support heating, trains, workplace, vehicle charging, synthetic fuels etc consumption. That puts us into the kW+ per person range and the only practical way forward there is nuclear (and no batteries are needed.)
