GFIs work only to ground. "Safe to Touch" does not specify this, so the average joe might think across the lines would be safe. Dangerous marketing! They are using 300V peak!!! That's mains, so totally not safe! And as meantioned falls under all the same safety standards.

 :palm: AC devices (minus incandescent bulbs and motors), have capacitors, exactly as I said and as shown in your pic. If they're transmitting power in 'packets' as people have been suggesting it would imply that it would be off for long periods. What that waveform would be then is the wave when it's on. So you'd have to have capacitors that store enough power to not only run during the zero crossing, but during the totally off periods! Then you'd have to transmit that power during the on periods! And why are they using a triangle wave?! That's just going to make noise (not nearly as bad as square), and provides less total power (area under the wave) than a sine wave!

EDIT: It doesn't go through 0 in the triangle wave. So there's the extra power. Which makes it just a pointless waveform imposed on DC!

Perhaps that's what a 300V square pulse looks like when you take into account rise times over that kind of wire and for that duration.

Seems, you did not see video. GFI is not only protection they are providing.

You shall catch the train and at least check basic operation parameters of tech we are talking here about. Otherwise you are having strong opinion about stuff you know close to nothing  :-DD

Period is 1.5ms, it's on for 1.1ms and "off" (which is not 0V) for 0.4ms.

Where do you see triangle wave?

Might it not be like running an extension cable?

Not if it were their intention to utilise or base a system around existing cabling which already incorporated telecoms and CAT5/6 network wiring, as a registered open cabler I have the technical standards and cabling regulations for AU and NZ here but as mentioned earlier they would probably differ dramatically from those used elsewhere.

Seems like they aim to get approval that their system is as safe as <= 48VDC systems. This is all over patent documents and marketing materials as well. Patent US20130103220A1: "Safe Exposed Conductor Power Distribution System". Thou, in video they show data center installation where power and data wiring is properly separated.
