So they probably won't let you use your existing wiring if it doesn't meet THEIR specs. So they will offer to rewire for you. ;) $$$ And yes, I think their "super hv safety" is total BS. Which is plenty terrible enough to throw this whole thing in the "dangerous snake oil" bin! EDIT: I bet if you ask them they won't tell you. Even if they do, it would probably be some BS. |

They talk about 18 gauge for maximum power throughput. I guess that means 18-2, RG-59 and likely CAT5 / 6 or whatever is common for CCTV / IP camera installation. |

I my case it is to WIFI a LED sign that is outside the building. From what you said there could be a chance to cheat by having the WIFI antenna very close to the sign power lines from inside the sign. Some of the RF should be coupled into the hydro lines? I could mount the other WIFI inside the building in the electrician's room to pick up a tiny bit of 2.4 GHz from the sign. Even with all the inherent hydro shielding the plastic breakers are plastic so some WIFI should leak out. Copper wire has to be better than fresh air. Maybe there would be just enough RF left for a reasonable WIFI connection?? --- End quote --- I think the dielectric loss is the factor at work. Homeplug auto selects frequencies between 2MHz and 100MHz or so, using whatever gives an acceptable SNR. --- End quote --- Good tip. I googled and they sell them at Canada computer stores for 60 bucks. They call it a power line adapter , same deal as homeplug . I will try and see if it works for a outside to inside building WIFI connection. |

This tech definitely shall not be seen as low cost power delivery in your house or flat :D Power inefficiencies? - Please explain what you mean. What's difference between 50/60 Hz interference compared to 650Hz? - None. Both are audible and both are not RF frequencies. It yet to be seen how much interference it creates. I bet it is much less than AC dimmers. What most of opponents do here are just uneducated speculations, some even did not read patent applications not to mention watching video ;) It's applicable to normal cheap power cable indeed. This is obvious. To power individually addressable LED panels in huge open office or airport you don't need to run Cat6 cable - use same cable you do for AC mains. Advantage is - you can run just single cable for whole ceiling, yet can on/off/dim each panel individually. DALI needs control cable which is extra installation costs. Voltserver allows conversion/retrofitting to smart lighting over existing cabling - this shall be considered as huge benefit. Will they succeed - this is good question. I hope they do because DC power delivery to modern loads is obvious path, more effective than AC. Just arcing and other safety issues shall be solved and this is what their tech is supposedly doing. Personally I wish them to succeed, I really hope they are not investor scammers :) |
