Electric field in motion

Published May 10, 2020

Engineers at Stanford have build a proof-of-con­cept sys­tem that could (some day) (it’s always “some day,” isn’t it?) recharge elec­tric cars while they’re dri­ving down the road.

It would work like a big­ger ver­sion of wire­less charg­ers for phones and oth­er elec­tron­ics: using an oscil­lat­ing elec­tric field. The trick was com­ing up with a way to effi­cient­ly charge some­thing that was mov­ing, because dis­tance changes the required frequency.

Next step: Scaling up in the lab to a sys­tem for recharg­ing fac­to­ry robots.
