Scientists have presented an unusual project that allows drones to stay in the sky almost indefinitely. Recharging is carried out directly in flight, thanks to remote recharge by a laser. The development is useful for the agricultural industry, MSCh, as well as other important areas of human activity.
The idea of the engineers is to transform the laser beam into a “charger” for the drone. A photodetector was placed on the device, which converts the incoming laser light into electricity. To bring the idea to life, it was necessary to create a specialized system that tracks the movements of the drone. It is able to detect the device regardless of weather conditions or time of day.
The efficiency on the transmitting side is in the range of 50–85%. Much depends on the power of the beam. But the device can accept “charging” rather poorly, losing up to 50%. But this is not critical, because tests are still being carried out, and the main goal, feeding the drone with a laser, has been successfully achieved.
If the system is worked out, gigantic prospects will open up. For example, it will be possible to control the movement of vehicles, use devices in rescue operations, etc.
