In the course of this unusual experiment, RSC Energia engineers had to solve a difficult task - to charge a mobile phone using a laser, the source of which was located at a distance of one and a half kilometers.
The whole process was somewhat reminiscent of shooting at a target from a sniper rifle, where the role of the rifle was assigned to a laser betrayal installation, which experts installed on the sixth floor of one of the buildings of the Moscow Region Korolyov.
A 10-centimeter target, installed 1.5 km away on the roof of another building, was a device that converts the energy of a laser beam into electricity, from where it was transmitted to a mobile phone charger. To the credit of RSC Energia's employees, the “shot” turned out to be truly a sniper one. Charging took one hour. At the moment, experts are calculating its effectiveness.
The next stage will be charging the drone hovering in the sky, and then the experiment will be continued in space on board the ISS, from where the crew members will transmit energy to the Progress transport ship via a laser channel.
