Who is blacking the free energy sources and why?
There are no "free" energy sources unless you have a car that runs on used french fry oil. As soon as more people have cars that can run on those, it won't be free, either.
Sure, the sun and wind are free, but the gizmos needed to harness them are as much or more expensive than fuel.
I think the neat thing here is that those little cars they are talking about from Tata not only are $2500 NEW, but had a 33 hp motor. With 33 hp you could get 80 mpg, I'm guessing. That's where the big saving is. We need to be coming up with cars that our gluttonous and debt ridden society can both afford to buy, but also feed.
Personally, I'd like to see us figuring out a way to run on methanol, which could be made from wood or coal, instead of trying to make ethanol and gasoline consuming machines that run on corn, which I consider to be insane, because as soon as we have a bad harvest, we'll be foolish enough to burn it instead of saving it to eat. I think we need to find something to burn things that don't require plowing, watering, fertilizers, and could be harvested in multi year cycles instead of once a year. The fewer times you have to run equipment through the field, the less of the output the tractor is going to consume.
