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.
