In this article, we want to tell you that electricity can be transmitted from a long distance, without using wires.
120 years ago, Nikola Tesla proved that there could be wireless electricity, but the usage of copper wires and its practicality was dominant so that he couldn’t do anything more.
Precisely this system works through shaped microwave beams, and they pass through relays, similar to repeaters. In New Zealand, the government already is financing and sponsoring wireless electricity beginnings, its work, and the testing.
Emrod, an energy startup, said that the beginnings of wireless electricity, especially in New Zealand, took place a century after the discovery made by Nikola Tesla. It was like the best performing satellite internet connections, only a clear line of sight was crucial.
If you didn’t know what ‘rectenna’ does, well, it reshapes the magnetic waves into electricity. It represents an element in a square form, that mounted on a pole acts as the pass-through point that keeps electricity beaming along, so a broader surface zone catches the entire wave. Besides, the whole beam is surrounded by a low power laser fence so it won’t zap passing birds and vehicles.
According to Emrod, if an outage appears, it can drive out a truck-mounted rectenna to make up for every missing relay legs.
This type of technology seems implausible. The issues like the loss of the signal fidelity during the transmission are the main problem. But Emrod’s relay technology refocuses the beam, that is why it seldom loses signal, and the best thing is that it never uses any power.
The effectiveness of the components used in the system is close to 100%. The most significant loss is in the transmission. They are using a solid-state, so the same electronic elements that can be found in every type of radar system, and in the microwaves at home. These electricity apparatuses are limited to 70% efficiency.
This project is sponsored by New Zealand’s electric utilities and the government. Moreover, Emrod posted on his site that the prototype received some government funding, and it was made and build in Auckland, in collaboration with Callaghan Innovation.
This project has received a Royal Society Award nomination and is the second-largest electricity distribution company in New Zealand. Also, Emrod added that Powerco would test first Emrod Technology.
In the beginning, the distance and power will be quite low, with a few kilowatts. But, later, hypothetically saying, the distance and energy will be in unfathomable amounts.
