9th grade student Nurali Amangeldiyev from the Abai region presented a unique device for transmitting energy using laser radiation in outer space. The project aims to solve the problem of energy supply for satellites and space stations in orbit, where vacuum and the absence of atmospheric interference allow the laser to transfer energy as efficiently as possible.
The device consists of two models symbolizing spaceships. One of them is equipped with a laser beam focusing system aimed at the second ship, which has a photoresistor that is sensitive exclusively to laser radiation. The laser beam hits a photoresistor, which through a converter generates electricity sufficient to power a light bulb and even charge a mobile phone. The device successfully transmitted energy over a distance of up to 10 meters and was tested in various conditions, including rain, snow and fog. The best results were recorded in a dark room and a vacuum chamber, where there was no light interference.
"There is a problem of lack of energy in space. I would like to help our astronauts by creating an installation capable of supporting their equipment. I spent more than two years developing it, using available materials to demonstrate the possibility of energy transfer in space. In space conditions, laser transmission will be even more effective due to the absence of radiation scattering factors," Nurali Amangeldiyev shared.
In 2019, he presented his project at the competition of the Moscow Institute of Physics and Technology, where he received high praise, and then improved the device by installing a more powerful laser and updating the software.
The young inventor plans to continue the development of the project and present it at the international competition in Baikonur. In the future, he intends to add solar panels to make the device autonomous and suitable not only for space, but also for domestic use — for example, to charge mobile phones via laser transmitters. This approach eliminates the need for wires and reduces the risk of overheating and fire.
