New Zealand-based startup Emrod has developed a safe method for wirelessly transmitting electric power across long distances without the need for copper wire.
The company has reported that it is currently working on implementing its system via a collaboration with the country's second-largest power distributor.
Nikola Tesla's dream
Though he burned out the dynamo at a local powerplant and caused a blackout in Colorado Springs in the process, in the 1890s Nikola Tesla proved he could power a light bulb from more than two miles away using a 140-foot Tesla coil.
Perhaps it's surprising then, that's it's taken a company this long to commercialize wireless power transmission.
Now, Powerco, the second-biggest distributor in New Zealand, is investing in Emrod, a startup that says it can efficiently transmit large amounts of electricity between any two points as long as they are in line-of-sight from each other.
Emrod has a working prototype of its device, NewAtlas reports, though it will build another one for Powerco, with plans to deliver by October, then spend several months testing. The prototype will reportedly be capable of delivering "only a few kilowatts" of power, but can easily be scaled up.
Taking on wired solutions
"We can use the exact same technology to transmit 100 times more power over much longer distances," Emrod founder and serial entrepreneur Greg Kushnir told NewAtlas. "Wireless systems using Emrod technology can transmit any amount of power current wired solutions transmit," he continued.
The system transmits electricity wirelessly via a transmitting antenna, a series of relays, and a receiving rectenna — a rectifying antenna that converts microwave energy into electricity.
The beams transmitted from the system's poles use the non-ionizing Industrial, Scientific and Medical band of the radio spectrum, including frequencies commonly used in Wi-Fi and Bluetooth.
