Tata Nano - should be electric

The Tata Nano seems perfect for an electric engine, and with a solar panel on the roof, it could start a mass-produced electric car revolution, not just in India but across the world. People would just need to get their buildings fitted out with a power outlet from which the car an be recharged overnight. It may take the cost of the car up a bit, but this would be offset by the non-dependence on petrol. It could actually be targeted at the upper middle class. Those just about ready to buy a three lakh($7,500) car, would jump at a 1.5 lakh($3,750) car.
