I read here about a revolutionary new battery which:
So there are 3 or 4 big issues with electric cars: (1) The long time taken to recharge during which the car is useless, (2) Short range, (3) Lack of infrastructure, (4) Low energy density of batteries compared to liquid fuels like gasoline. This causes the weight of the engine/fuel to be much higher. So lowering the efficiency.
I discussed the prospects of electric cabs with one of the cab drivers who drives me on my daily journey to work. He thinks electric cars need to be a lot better to be useable as cabs. Meanwhile the local council want every cabbie to have an electric cab in 5 years. My cabbie thinks the local council don't give a toss whether the tech works or not. I think they just want to be seen to be 'saving the planet'.
PS: The local council in question is St Albans in England. It's not a "socialist" council, nor is it Enviro-Stalinist. It is split between Tories and Lib Dems. The electric cab initiative is mostly Lib Dem - who are like a light green Green Party.
"We are now consulting on the Councils proposals to introduce fully electric Hackney Carriages and Private Hire Vehicles to be licensed. The consultation will last for 12 weeks and will end on 15th June 2017,we hope to report the responses to the Licensing and Regulatory Committee on 18th July."
