Re: Great looking but...
"My country's National Grid hasn't got the capacity to generate or deliver enough electricity to run the nation's cars if they were all electric."
Are you in India?
I know that the US and GB both have the capacity to charge a large number of electric cars off-peak. In fact, the electric companies would love it if more people were buying power in the middle of the night.
Roof top solar systems start making a lot of sense if one has an electric car which also lowers the impact on the Grid.
