Viziv Technologies is a company that claims to be able to transform power delivery, signaling and safety. [Their "Science" page says](https://vizivtechnologies.com/science/):

> 
> The Zenneck surface wave is a technological breakthrough enabling the world to “cut the cord” between power generation facilities and local distribution grids. This new technological development represents a paradigm shift in the science of electromagnetic waves with wide and varying applications.

> A ZSW is a type of electromagnetic wave that travels along the earth, bound to its surface. Small size, controlled dispersion, low attenuation, and efficient operation are all features of ZSW systems, making them attractive for any application that requires moving energy and information from one point to another over the surface of the earth.

> This new concept in wireless systems will transform many industries, including power delivery and global positioning technology. Additionally, it will transform the way every industry operates, leading to greater efficiency across the board, as well as greater human and environmental safety around the globe.

There's [another page](https://vizivtechnologies.com/science/physics/) about the physics, but it's under construction.

I'm asking if this technology is plausible. The paragraphs above are written in a way that makes me cautious, because they read like fluffy pseudoscience where the author uses technical physics terms but without actual physics. My initial reaction for example is that the second paragraph is impossible, since electromagnetic waves will not be bound to the surface of the Earth but shoot off into space. However, a quick Google search shows that [Zenneck surface waves](https://en.wikipedia.org/wiki/Zenneck_wave) really are a thing, although the Wikipedia page is also short on details and is too technical for me to readily grasp.

Viziv Technologies also claims to be able to improve power transmission. My understanding of how power is transmitted is via wires, which is very efficient because the amount of energy lost during transmission ($=I^2R$) is low at high voltages. On the other hand it sounds like Viziv's technology is going transmit power wirelessly, which should be an advantage. I'm aware that [some devices](https://www.androidauthority.com/phones-with-wireless-charging-848173/) can already be charged wirelessly, but this isn't at the scale which Viziv claims to do.

Overall the page reads like pseudoscience, but there are enough concerns to make me not sure. Therefore I'd like to ask if anyone more familiar with electromagnetism can diagnose if this is really pseudoscience or not.
