One that doesn't burn fossil fuel in order to charge. And one that isn't destroying the earth digging holes to hell with tractors and trucks that are burning fossil fuels in order to find a couple grams of battery material. One that isn't going to be sitting in a landfill with a quite large battery pollutionizing the ground all around. I don't think their batteries will be recycled, not on a large scale anyway.
Not that I think a gas burner is innocent of all pollution charges, I just don't think a Tata is green just because it doesn't consume petroleum directly for propulsion.
