New Zealand's startup company, Emrod, wants to make Nikola Tesla's idea to become a reality. Thanks to Powerco, the country's second-largest utility, funded its project to conduct a test of its system grid-connected commercial power station.

The NZ startup hopes to provide energy to those from the power station or transmit power from remote renewable sources, such as offshore wind farms. Tesla's most audacious idea is to power the world without wires.
His plans for a "world wireless system" were funded by JP Morgan. However, the scientist's dreams didn't become a reality. On the other hand, Guglielmo Marconi, Tesla's peer, had a similar proposal to Nikola Tesla's idea.
Marconi's dream, the wireless transmission of information on radio waves, has a far greater success since the world currently has wireless information transmission.
Tesla's idea of wireless power transmission could also be a reality if New Zealand's experiment becomes a success. Emrod's new system consists of four components: a transmitting antenna, rectenna, power source, and several transmitting relays.
The company uses energy in the ISM (industrial, scientific, and medical) band and keeps the power density low.
"It's not just how much power you deliver, it's how much power you deliver per square meter," said Greg Kushnir, Emrod's founder.
"The levels of density we're using are relatively low," he said.
How Emrod's system works
Just like Marconi's radio waves, the system's transmitting antenna transforms electricity into microwave energy. But, it will be focused into a cylindrical beam and will be more energetic.

To convert it back into electricity, the microwave beam is sent through a series of relays until it hits the antenna. If this works, the researchers claimed that the beam won't ever contact anything but empty air.
It is also safe for humans since it uses a net of lasers, which surround the beams, detecting obstructions such as birds or even persons. Once it detects moving objects, it will automatically shut off until the obstacle moved out of the area.
