"Wi-fi" but for energy? COOL!

The company Emrod is already transmitting energy over kilometers without cables, using microwaves and laser-based safety.
In Finland 🇫🇮

1. Just be careful you do not wander or walk thru one of thems electro magnetic beams

8. The description is that it is dangerous, but it's up in the air, with laser detection to turn it off when a bird

would fly through it.

EMROD’s system has a number of features that ensure that no human or animal can be exposed to the power beam.

Firstly, the transmitting and receiving antennas are elevated above ground (just as high-tension cables are) to eliminate human intervention in the power beam. The beam itself is highly directional and collimated as it is formed in the near-field or Fresnel region. The power distribution both along the beam axis and across it are not governed by the more familiar far-field, Fraunhofer region of an antenna. As such, the receiving antenna collects >97% of the power emitted by the transmitter with carefully designed beam forming. There are no issues with sidelobes with a beam of this nature since the power is confined to a cylindrical ‘tube’ between transmitter and receiver.

In addition, the laser safety curtain around the periphery of the antennas encompasses the entire beam and can detect beam incursions from the likes of birds prior to entry into the beam. This triggers a temporary power shut-down thereby avoiding exposure to the full beam power. The density of the power beam and the frequency used also means that an object would have to stay in the beam for more than a few minutes to experience any thermal effect. However, the safety shut down system prevents any objects from interacting with the beam.

I can't find any mention of Finland on they website, though, which looks suspicious. Their "Use Cases" page points to a 2021 page saying a field demonstration would start in New Zealand in 2022. Which does give the impression it's vapourware - lots of talk, nothing concrete. We need more than an AI video, certainly. They did get a grant from the German government for development in 2024.

10. Possible health concerns involving Electro magnetic radiation fields

Introduction
Electromagnetic fields (EMF) and their effects on the health of humans and livestock have been a source of debate. Since the early 1970s, there have been concerns about EMFs and possible negative effects on health. Many scientists have conducted EMF research to determine if there is a link between exposure to EMFs and adverse health events, most notably cancer. These studies indicate that EMF exposure can have a biological effect, but the effect is not always negative. This effect depends upon the strength of the EMF and the duration of exposure. The majority of research in this area has focused on human subjects, and therefore data documenting the effects of EMF exposure and livestock production are limited. Increased installation of transmission lines in novel areas is occurring due to an increase in renewable energy generation from wind and solar production methods. Areas of the U.S. not typically involved in energy production are becoming energy exporters, requiring the construction of new high-capacity transmission lines. These lines are a common source of EMFs in the environment. This has renewed conversations and debate as to whether transmission line exposure carries increased risk of adverse health effects for humans and livestock in proximity to transmission lines.

2. Nikola Tesla tried something like this about 120 years ago

[buzzycrumbhunger]

3. Yes!!

First thing I thought of, too!

4. And got shut down by the money men because his idea was to give free energy to the people.

Unless there's potential for profit, it won't go anywhere.

5. Tesla was a man that created tech that the world wasn't ready for at the time.

He did discover Electrical Alternating Current and that has been put in billions of homes.

6. And got shut down because he wanted to fill the air with intense alternating electric fields, which are very dangerous.

Watches quit working, their delicate mechanisms welded together. Metal equipment gave off sparks. Dental fillings produced intense pain. All exactly to be expected when you are dumping that much electrical energy into the immediate environment. Transmission to more distant locations is grossly inefficient, as there are so many mechanisms for energy loss, and they are all in effect.

People could not live in such an environment for extended periods of time, and digital electronic devices would be fried even without being turned on. I suspect even some batteries could be made to explode. Bad news for anyone with pacemakers or even hearing aids. Oh, or watches. Or cell phones. Or cameras. Or tablets. Or GPS. Or calculators. Or, or, or ...

Everyone thinks Tesla was a genius, but really, he had a few good ideas at the start of his career and the rest were pretty nuts. In "planning" to transmit free energy to everyone, Tesla did not propose or discover a new source of energy -- it all came from electrical generators operated by burning fuel, or from hydropower. There was nothing inherently "free" about it. When Tesla ran his high-voltage, high-frequency transformers in his lab to demonstrate some spectacular show of discharges or whatever, the adjacent town often went dark, because all the local electrical power was being sucked up by his lab.

Unfortunately, "fans" of Tesla's inventions -- at least those which were never built -- fall into the usual magical thinking of cults everywhere, and insist he was the victim of conspiracies by The Powers That Be who set out to ruin every good idea anyone dreams up. No one had to derail Tesla; he did that himself. He rejected modern theories of physics even after they had passed every test that could be thrown at them. He attributed the inspiration for his inventions and theories to a mythical goddess. And those who adore this kind of 'woo' are his most ardent fans. (One biographer claimed Tesla was from the planet Venus. Her book was printed entirely in green ink. Not the kind of source you should take seriously.) Read the facts on the physics of HOW his inventions actually functioned, and you realize that what he specialized in was the transformation and expenditure of enormous amounts of electrical energy, not its production. No solution to an energy crisis there, but overuse of his ideas could make things a lot worse. There is no forgotten or suppressed magic to save us.

7. Ooooh, am I the first to say "what could possibly go wrong" ?

Because someone has to.
