New Zealand test wireless power lines

The New Zealand Startup EMROD with the support of the state is developing a system of wireless transmission of electricity for long distances, which can replace traditional transmission lines.

Since the days of Nikola Tesla, many engineers tried to develop practical technology for transferring a large amount of electricity through air, which could be used on an industrial scale. Although it is based on the same transformation principles as in any radio system, but in this case, due to high power, the key parameter is effective.

Engineers from EMROD argue that they have found a solution to this problem, combining ideas from the work of optical and radar systems with metamaterials. Unlike cellular taps and radio antenna, created by them, the quasi-optical system converts electricity into a focused cylindrical beam of microwave radiation, directing it to the matrix of the next receiver. Thus, the energy can be transmitted along the chain and distributed between consumers.

The specific signal power is about 1 kW per m2, so along the edges of the receiver panels are lasers directed to the sensor matrix of the previous transmitter. If at least one of the signals is interrupted, for example, flying a bird, then the system for this time stops the generation of microwave radiation.

Currently, the team is working on the creation of a system transmitting energy to a distance of 40 m, whose field tests should begin next year. The current prototype operates at a distance of two meters. A bottleneck of the technology is the transmitter, the effectiveness of which is approximately 70%, but the development of 5G will contribute to the upgrade system.

The project has already become interested in the Government of New Zealand and began to provide companies support. The authorities want to learn about the possibility of using technology for energy supply of remote areas and places with difficulty locality, where the gasket and maintenance of traditional power lines requires huge costs.
