The dream of energy transmitted without the need for cables, freely in the world, is noble and highly advanced but has ancient roots.
In 1890, 130 years before Emrod, the startup of which I will tell you, a genius of first magnitude like Nikola Tesla opened to a future of wireless energy. The inventor proved that he could power light bulbs from more than 3 kilometers (two miles) away. His 42-meter (140-foot) "Tesla coil" succeeded perfectly. Unfortunately, the dynamo of the local power plant burned down and plunged the entire town of Colorado Springs into a blackout. 11.000 inhabitants who would soon run into the effects of Nikola Tesla's secrets.
The father of modern electricity had many, and many of them he brought with him (or were stolen), but after that attempt with "bittersweet" effects he fell back on other experiments and other goals.
Today a startup in New Zealand believes it can complete what Tesla (and Witricity) left in half. His dream of transmitting energy wirelessly may come true soon. The startup, Emrod, managed to convince an important energy distributor to create a commercial version of this type of distribution.
Why is it so exciting?
Emrod sees wireless transmission as a key technology for renewable energy, which is often generated far from where it is needed. This type of system could be great for bringing offshore and remote renewable power generation products to urban grids without the need for giant storage batteries and the like. One of Tesla's secrets involved the exploitation of stationary terrestrial waves, distributed on the surface of the Earth, to transmit energy from one point to another on the planet. Energy that would then have been enough to simply "capture" with a plant. A bit like you do to pick up a radio broadcast.
How Emrod's wireless energy works
Emrod's system uses one transmitting antenna, one set of relays and one rectenna receiving. It is a "straightening" antenna, capable of converting the microwave energy emitted by the system into electricity. Needless to say, unlike Tesla's dream of free and globally accessible energy, Emrod's is radiated directly between specific points that are on a specific path.
Emrod claims that the system works in all weather conditions (rain, fog and even dust storms). The transmission distance is limited only by a line of sight between each relay. This is why Emrod energy has the potential to transmit energy thousands of kilometers, at a fraction of the infrastructure, maintenance and environmental impact costs imposed by a wired solution.
Now Emrod will take several months in laboratory tests before moving on to a field test. If it works, wireless power transmission will soon be a reality.
Nikola Tesla's secrets are safe, however. And I suspect that as I am, I am not destined for an appetite. Why give what you can pay for free? Intercom JPMorgan.
