Countries around the world are now trying to combat global warming. Shifting from gasoline-powered vehicles to electric vehicles (EVs) is one way to reduce CO2 emissions. Yet adoption of EVs has been slow, partly due to issues with EV batteries. They take a long time to recharge, and most do not offer a cruising range that is comparable to gasoline-powered cars. Professor emeritus Takashi OHIRA of Toyohashi University of Technology is working on the development of a wireless power transfer technology that can run a motor by receiving high-frequency wave energy from the road, even without a battery in the car. In this episode, we will introduce Dr. OHIRA's groundbreaking technology, which he has developed from scratch to power a passenger car.
