New Zealanders will test the prototype system of microwave transmission of electricity

New Zealand company agreed with the local electricity supplier about testing a prototype system of microwave transmission. The technology is safe for living beings and high efficiency of the receptor. Testing will begin with the transmission of two kilowatts and will gradually scale up to commercial capacity, said the developers in an interview with the New Atlas.

The idea of electric power transmission by radio waves is nothing new. Rectifying antennas known from the first half of the XX century, in the 60s in the US were testing the helicopter with microwave meals, and now experiencing transmission satellites. However, this system has not found wide commercial or practical application for several reasons. When radio transmission is lost between one half and one third of the energy and developers need to reach a compromise between antenna size on the one hand and efficiency and safety on the other.

The second largest electricity supplier in New Zealand, Powerco, allocated funding company Emrod. The company shall conduct testing of the prototype system of microwave transmission of energy at a level suitable for commercial use. The current (first) prototype is to transmit only a few kilowatts per kilometer, and in the finished system will be able to transfer energy to tens of kilometers between the two towers while maintaining line of sight.

CEO Greg Kushnir (Greg Kushnir) States that to market them will allow two solutions. The first is an extremely efficient receiving antenna. Device details not yet known, but the coefficient of performance, the assurance of developers, should be close to one hundred percent due to the use of radar absorbing metamaterials. Thus, the final efficiency of the system will depend on the transmitting device, and the existing prototype it is approximately equal to 70 percent. This is a significant loss, but are not so big if you compare with a wired low-voltage grid (10-15 percent). Representatives of the company hope to increase the energy efficiency of radioizluchenie due to the development of 5G networks.
