And it can be used on any aircraft that uses electric propulsion.
The Defense Advanced Research Projects Agency (DARPA) has funded a company called Electric Sky to build a prototype for a wireless charger for its drone swarms.
The concept of wireless power has been around for many years now, and innovators have used different techniques such as lasers and microwaves, to name a few. The most common complaint of these techniques, however, is that the charging gets weaker as the distance between the transmitter and the receiver increases. Seattle-based Electric Sky has proposed a solution that addresses this issue.
