Satellites will soon be able to transmit electricity anywhere on Earth
The European Space Agency (ESA) wants to develop solar energy in space. The electric current will then be sent to Earth, and it will be available day and night. In this context, the New Zealand company amrod The European Space Agency has demonstrated its technology for Wireless transmission of electricity.
The current prototype uses antennas measuring 1.92 meters in size to transmit and receive energy. Energy is transmitted in the form ofElectromagnetic waves In the ISM (Industrial, Scientific, and Medical) frequency bands, near Wi-Fi, it is a beam directed between two points allowing little radiation to pass around it. To prove them, the antennas were separated by a distance of 36 meters, but they have already conducted tests at a distance of more than 200 meters.

Transmission of electricity via satellite
While the Emrod transmission system could be used to send collected energy from space to Earth, this is not the company’s long-term vision. Its founder, Greg Kushner, envisions, instead, a global wireless electricity network that will travel through it Satellites In low orbit, 100 km above sea level. At this height, the antennas should be 30-40 meters. With current technology, Greg Kushner estimates it could achieve 60-70% efficiency, but hopes by 2040-2050 it will be closer to 80-85%, better than some wired networks.
Its goal is to completely separate the production of renewable energies from their use. with system from satelliteIt would be possible to install solar panels in the desert and send the electricity produced to the other side of the world. Thus it will be possible to take advantage of solar energy 24 hours a day, and isolated places can receive …
