New Zealand company Emrod has developed technology capable of transmitting electricity without cables or electrical wires. I explained this to the European Space Agency, which aims to produce solar energy in space and send it back to Earth day and night.
Emrod uses 1.92m antennas, through which it can transmit and receive electrical energy in the form of electromagnetic waves similar to Wi-Fi. In a demonstration at the European Space Agency, the company uses antennas separated by 36 meters, but claims to have already successfully passed tests with antennas placed 200 meters apart. This new technology could be useful for the European Space Agency’s space solar power generation plans, but its developer has other ambitions for it.
The New Zealand company plans to use it to create a global wireless power grid that will transmit electricity via low-orbit satellites located 100 km above sea level. In this case, the height of the antennas should be 30-40 meters. Greg Kushner, founder of Emrod, expects 60-70% efficiency for this device with this technology in its current state. This efficiency should be improved by 2050 to reach an efficiency of about 85%, a performance that will be better than that of some cable networks.
Deployment of this technology may eventually enable the installation of solar panels in the desert and the ability to send the electricity produced by these installations to the other side of the planet. This technology is scheduled to be commercialized in 2024.
