Goodyear wants to harness fundamental principle of physics that when you use energy, some of it is lost.

The company is dreaming up a product that could, theoretically, convert the heat generated from the friction of movement back into power for the battery.

Companies have tried to overcome this by installing hardware that harvests this lost heat, most famously in regenerative breaking.

The project which is named BHO3 will work in one of two ways;

Either, the company would add in thermoelectric materials that could absorb heat as the rubber rolls along the road.

Alternatively, it could use a piezoelectric substance that would generate power when compressed.

At sad bit is that such technology only resides in the imagination of Goodyear’s design team and isn’t expected to exist for another 15 years.
