Goodyear Wants to Power Your Car Using Heat From the Tires

We were all taught in middle and high school science classes that friction produces heat. One common example of this is the friction and heat created by car tires moving across pavement. Most of the time, that energy goes to waste, which electric car companies try to minimize in order to keep batteries charged.

Never Inflate Your Car or Bike Tires Again—Soon, They'll Do It Themselves

Goodyear is developing self-inflating tires for trucks and cars, while a San Francisco startup wants to do the same for bikes


Humans are not naturally efficient beings. Despite our best three-cups-of-coffee, getting-things-done intentions, we meander, we forget, we waste. And in the aggregate, all these tiny sins—leaving the lights on, turning the air conditioning up, buying too much food at the grocery store—make us use more energy than we need to. Case in point: Drivers know somewhere in their brains that driving with tires at the proper pressure saves gas. But when was the last time you checked the pressure or reinflated them?

Sure, there are the super-humans among us that never forget about things like this. But most of us aren’t, which is why the U.S. Department of Energy gave Goodyear $1.5 million this month to work on tires that monitor their own pressure and inflate themselves.
