Both [[Nikola Tesla]] and [[Hidetsugu Yagi]] attempted to devise systems for large scale wireless power transmission in the late 1800s and early 1900s, without commercial success.

In November 2009, LaserMotive won the NASA 2009 Power Beaming Challenge by powering a cable climber 1&nbsp;km vertically using a ground-based laser transmitter. The system produced up to 1&nbsp;kW of power at the receiver end. In August 2010, NASA contracted with private companies to pursue the design of laser power beaming systems to power low earth orbit satellites and to launch rockets using laser power beams.

Wireless power transmission has been studied for transmission of power from [[solar power satellite]]s to the earth. A high power array of [[microwave]] or laser transmitters would beam power to a [[rectenna]]. Major engineering and economic challenges face any solar power satellite project.
