from the are-you-*sure*-that-will-scale-up? dept.

Converting the energy of a moving automobile into an efficient power source for that same automobile is one of the Holy Grails of motor transport, and new research suggests an important part of the solution could be to look at the friction generated between car tyres and the road itself.

Engineers from the University of Wisconsin-Madison in the US have developed a nanogenerator that’s capable of harvesting the energy produced by the friction of a tyre rolling along the ground.

For those aren't going to RTFA no matter what: Their test vehicle was a toy car, so I've got some concerns about whether or not this will scale up to full-sized models. But if it does, it could potentially vast increase the range of electric cars, or allow them to use smaller batteries.

    It won't work on my car. My car has tires, not tyres.

    'Murica!

    I see, your car is tired. Maybe it needs some coffee.
