Intel claims wireless electric power transmission

Has been discussed here before. It will violate any and al radiation sp[ec. may fry your cat too perhaps. It is not 'green' as it loses a lot of power, it is too big for small equipment.

Wonder hat happens to your short wave radio if yo uhold it close to it. So, crap.

Always a chuckle, hearing digital's view of the elephant.

Depends on the wavelength they use. There was a very amusing instance of a radio ham in allotments under a major UK transmitter mast who heated his greenhouse for free with a suitable resonant tank circuit and resistive load.

Compared to the transmitters total output one greenhouse wasn't too bad, but the authorities noticed after several others copied his design.

The technology might be useful for recharging electric toothbrushes I suppose.

It is even easier to make a fluoro tube light by holding one end and pointing the other upwards towards a supergrid pylon. Several artistic photos of tubes stuck in the ground under pylons have been done. eg

Is one of the better ones.

Amazing!

I can light up a neon if I hold it close to my transmit antenna.

Interesting, do you have more details or a link?

Yeah, it was in our morning paper as well. So they re-invented the series resonant converter?

At 13.56MHz or some other ISM band in the shortwave range you could get away with it.

Yes, very cool.

It can really puzzle people if you have a morse code test loop going (which from a legal POV you should anyhow). Then it's like "Look, E.T. is trying to talk to us now".

I dunno, CB (27MHz) is free here, the CEPT rules (for much of Europe) are max power: 1W AM, 4W SSB, 4W FM.

Just keeping the mike button pushed on FM without modulation seems to happen a lot....

There was an interesting calculation some time ago in sci.astro, or sci.physics (do not remember, maybe both), about the fact that we will not be able to receive transmissions from other planets as the signal would simply be too weak....

But sure, if they land in your garden, then anything goes. Did you see the movie: Mars attacks?

Yeah, on CB it seems that anything goes. I never did CB, went for the ham radio license right away.

Nah, I really don't like Sci-Fi stuff. Never did.

aha, amateur, I went for the real thing, working at the TV station :-) TV always fascinated me more then radio.

You mean you never tried dlithium crystals?

Sounds a bit apocryphal! The majority of 'major' stayed masts in the UK for broadcasting carry VHF and UHF services with vertical radiation patterns that have a null in the 'under' direction. Perhaps this relates to MF or LF, or perhaps even HF. The major LF station is Droitwich 198 kHz which uses a 'T' supported by two masts. Another M Brown has lots of details of the stations in a public web site at

I hope they unplugged it first.
