Battery powered autos would be great if you could get any power or distance from them. No sun in the winter means no solar power for a solar powered car. Another problem is that you have to plug them in and charge them creating more cost for your electric bill which causes greater use from your power plants. They also worsen the environment from the pollution the fumes give off when they are being charged. Some people get the idea that battery powered cars are great, but they don't realize the power to recharge the batteries doesn't come from the jellybean factory. Good luck.
