Researchers showed off an electric car without batteries. It gets powered wirelessly through the road.

Batteries are a big bottleneck in today's electric cars. Japanese scientists at the Toyohashi University of Technology have a solution for the battery problem. They showed off an electric car without batteries. The electric power is transmitted wirelessly to the car from the road.

The researchers paved a 30 meter stretch of road and integrated power transmitters. As you can see in the video below the single seater electric car is driving. The driver is taking safety very seriously and wears a helmet, despite rather low speeds.

The system uses a frequency of 13.56MHz based wireless power transmission that can transfer 5kW. Wireless power transfer is always associated with loss and poor efficiency. This fact and the requirement to build special roads will be the biggest obstacles to bring battery-less electric cars to the market.
