Electricity Without The Wires

Category: In The Media,PersonalChrisM @ 3:09 pm

I remember watching Tomorrows World a long time ago, and seeing a piece on mains sockets that didn’t have any sockets. That is to say, you could attach a ‘plug’ to any part of the wall, and electricity would be supplied (I’m guessing through induction coils or something similar?).

Well, the next step beyond no specific sockets on a wall to supply electricity is no connection at all!

According to this article over at the BBC, the system uses resonance to transmit power through the air…
no wires

Key
1) Power from the mains supply to a copper antenna
2) Antenna resonates at a frequency of around 10MHz, producing EM(electromagnetic) waves
3) Waves of energy from antenna travel up to 2 metres (6.5ft)
4) Electricity picked up by laptop’s antenna, which must also be resonating at 10MHz. Energy used to re-charge device
5) Energy not transferred to laptop re-absorbed by source antenna. People/other objects not affected as they do not resonate at 10MHz

Kilowatt PSUs !!!

Category: In The Media,PersonalChrisM @ 2:50 am

That means, if you were to use the power supply to its maximum output, you’d be using as much electricity as sixteen standard (60w) light bulbs.
Obviously, even with a powerful PC (quad core CPU, quad SLI grafx, fast memory, all OCed, a few hard drives and DVD burners, lights/cathodes and enough fans to keep it all cool) you’ll not actually quite need that much power… yet.
Better to have capacity to spare than to suffer your PC crashing, or in a worst case scenario, have a cheap PSU die and send a nasty spike to kill your m/board…

Anyway, for a proper review of the Tagan 1100 Watt Power Supply, check out here, also includes a little info on the upcoming 2Kw PSUs!

I’ve been updating the pages on all my article sites this evening, so whilst waiting for them to finish uploading, I had some spare time to write these last three posts, in case anyone thinks they are a little off the norm.
