Car Charging On-The-Go

BOB HIRSHON (host):

Wireless car charging. I’m Bob Hirshon and this is Science Update.

Some small cordless appliances can charge up while being close to a charging station, without being plugged in themselves. But they have to be motionless. Now, Stanford electrical engineer Shanhui Fan and his colleagues report in the journal Nature on a technology to charge devices wirelessly on the move.

SHANHUI FAN (Stanford University):

You can think about, for example, transferring into a moving vehicle, or into any other moving objects.

HIRSHON:

Electric cars could charge up while driving over electrical coils embedded in a road, giving the cars essentially unlimited range.

FAN:

Another simple example is you have a device on your body that need to be charged.

HIRSHON:

Like cell phones that would charge as you walk around a room. The team is now working on increasing the power they can transfer to levels that would make these applications practical. I’m Bob Hirshon, for AAAS, the science society.
