What if your car could be powered where the rubber meets the road? Range anxiety persists as a fear among electric car drivers, as heavy batteries with limited capacity remain slow to charge. Goodyear has announced its concept for a heat-gathering, electricity-generating tire at the 2015 Geneva International Auto Show, and the tire could change all that by making a few changes to an oft-overlooked component.
Goodyear is admittedly a little vague on the details of the BH03 concept tire, but what they do tell us is this: the tire would capture the heat generated by the friction of the tire rolling along the road, as well as from the flexing of the tire under normal driving conditions. In addition to that, the tire itself—in the form of a layer of thermo-piezoelectric material—could capture light and heat when the vehicle is stationary, and transform that into more electricity.
The specs on how this would all hook up to the battery pack of a car remains unknown, nor are there any details as to a potential release date, price or availability. We’re waiting anxiously.

If I design my own car. I would defo use this.
This wold go perfectcly on a BMW i8 model. Even the style is the same. Great idea!
There’s definitely plenty of energy to be collected between the friction heat and compression of a tire (Try putting your hand on one that isn’t properly inflated after a long trip.), but I’m going to call bull on the solar component. Small area, close to the ground, frequently shadowed by the car, other cars, or walls, at a terrible angle, and usually covered with road grime? No way it’d be worth the expense, added complexity, or any sacrifices made to durability or tread shape to accommodate it.
Intriguing idea. However, I'm extremely confused as to why Goodyear would release a "concept" for such a device rather than waiting until they had a working prototype? Now other companies can take this "concept" and start working on it and possibly even surpass Goodyear when it comes to putting such a product on the market.
