Hi Baros! Tesla died a long time ago, and any patents he may have filed will have expired a long time ago.

I make no such claims to his patents, since I’m not a scientist.

I don’t like when some dirty scientist take credit for things that invented Nikola Tesla in his life time :/ why do you steal things that are not yours? why do you claim you invented them? Witricity is only using Tesla patents.

Hi Patrick and thanks for the comment!

I’d read about the frequency issue in a more academic document at the time, but didn’t think it was mentionable. The reason being it’s most likely one of those things that will be resolved as the technology matures.

Thanks again…

Uhm, for your info guys, this stuff can be extremely dangerous if there’s some kind of malfunction. If the resonance is interfered, even slightly, you could have all that electricity pass through your body, just like it’s passing through the lightbulb.

The key to this wireless electricity stuff is the frequency at which the electricity is transmitted at. High frequencies will travel along your skin, but not penetrate it. At a certain point though, when the frequency is lower, the electricity can pass through you. Not fun.

Well the important thing for me, you being the resident scientist, is that you didn’t laugh out loud at my prognostications.

So anything else is a bonus.

But seriously, I think the potential is amazing, assuming the distance and efficiency issues can be resolved, which I suspect will be just a time thing…

Cambridge company Splashpower for which a friend of mine is the Big Cheese are almost ready to market their version of wireless electricity far sooner than Witricity will be available. But, aside from the likely scaremongering…I mean, ahem, safety concerns that witricity will bring, there is the problem of efficiency.

Copper wiring is pretty efficient at carrying power from an outlet to a device. Induction devices are much less so. We already lose 8% in “standby” mode. the desire to ditch the spaghetti behind the TV will do nothing more than add to our carbon footprint. Just get some cable tidies instead.
