Goodyear(GT) working on an energy-harvesting tire

타이어에서 생기는 마찰열을 다시 에너지로 바꿀수 있을까? 좀 sci-fi 같은데... 이런 뉴스를 계속 흘려야 광고가 되겠지요. 중저가 타이어중에서는 GT가 전 젤 좋다고 생각하고 있습니다.

Goodyear's working on an energy-harvesting tire

It's a fundamental principle of physics that when you use energy, say to run an electric car, some of it is lost. Companies have tried to overcome this by installing hardware that harvests this lost heat, most famously in regenerative breaking. Goodyear is hoping to do a similar thing with tyres, dreaming up a product that could, theoretically, convert the heat generated from the friction of movement back into power for the battery.

The romantically named BHO3 would 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. Unfortunately, such technology only resides in the imagination of Goodyear's design team and isn't expected to exist for another 15 years. Hopefully, before then, Elon Musk will have gotten laser-powered hover vehicles to the point where we can all buy one.
