Viziv Technologies claims that they are researching the ability to send and receive electricity using the Zenneck Surface Waves.

August 2019 press release

Viziv Technologies, LLC, and Baylor University announce a new research partnership aimed at commercializing an entirely new means of delivering electrical energy wirelessly over long distances. Over four decades in development, Viziv’s systems use a phenomenon known as a Zenneck surface wave to propagate electromagnetic waves along the interface of earth and air. Viziv’s ultimate goal is to provide the capability to safely, economically and efficiently deliver electrical power virtually anywhere in the world through the use of surface wave technologies.

There's a big tower they built similar to the one Nikola Tesla built. I haven't seen a single proof of concept that verifies that it works.

If this is proven technology, I would think everyone would be talking about this. This could be the single greatest technological revolution since the steam engine.

    Are you asking about the Zenneck wave specifically, or wireless power transfer in general? That "works" well enough, it's just not really viable for large-scale provisioning of whole communities for a variety of reasons. – DevSolar Sep 23 '20 at 7:52

    Hello @Finesser, I really appreciate the effort you put in this question but I am having trouble imagining how we can answer this. If this is about the theory of wireless power transfer and Zenneck Surface Waves then Physics.SE might be a better fit. If you are skeptical about the fact that this could be a commercial product, then it seems this is an ongoing current event because the quote you give says that they are still researching and developing. So what is it exactly that makes you skeptical? – Jordy Sep 23 '20 at 9:38

    @tuskiomi I'm not familiar with Zenneck waves, but I can imagine a situation in which a certain guided mode of propagation leads to particularly low loss transmission, like a soliton. – 0xDBFB7 Sep 24 '20 at 14:46

    @tuskiomi ah - how did you arrive at that figure? I might be missing something here. – 0xDBFB7 Sep 24 '20 at 14:49

    @0xDBFB7 80% input power conversion efficiency * 50% modulation efficiency * 98% antenna efficiency * 75% reception efficiency * 80% receiver power conversion efficiency. This gives at most, 23.5% efficiency if you build a capturing apparatus over the entire plant. The average US citizen lives 19.06 miles from a power plant, and if the receiver is as big as the transmitter, that corresponds to 32.6 urad of arc length, which works out to 0.00021% efficiency with a dipole emitter. 1.8 was a generous over-estimation. – tuskiomi Sep 24 '20 at 20:04
