Wirelessly charging a drone in flight – BBC Click
Engineers from the Russian subsidiary of Global Energy Transmission (GET) Corporation have presented a wireless power transmission system that can charge electric drones during flight.
The technology will potentially allow the UAV to stay in the air for almost infinite time. The existing prototype of the system is capable of remotely transmitting a charge of up to 12 kW at a distance of 8 meters. The work uses a three-phase power source of 15 kW, so one cell can charge three flying vehicles at once. However, the current efficiency is 80% and drops sharply above 8 meters..
At the moment, engineers continue to improve technology, increase efficiency and range. In the future, the developers want to implement Nikola Tesla’s ideas about the transfer of charge without significant losses. GET intends to create a worldwide wireless energy network to support commercial drones, robotics and industrial equipment. The system is planned to provide fast charging in the future thanks to a global network of powerful «access points».
Another promising area of energy is the development of solar cell technology. Researchers from Golden have been able to achieve a sufficiently high efficiency of flexible perovskite photocells, at the same time making them stronger, which will allow them to cover windows of office buildings, vehicles, electronics and even clothing with them..
