I wonder when it will be possible to connect to your TVs, VCRs, DVD players, etc, without wires?

I said to my mum, probably in about 15-20 years. Am I far out? :eek:
 
And don't say batteries! :D :D

I asked Doctor Who and he told me that when that time comes, the gadgets will have different names :)
 
I am afraid that it never will work.

Not as long as we use electrical power

But, perhaps, some small portable nuke system ? Still not wireless

Yep the technology is coming and its not that far off. saw a technolgy report on BBC news one saturday morning around 2 months ago, they have already invented wireless mobile phone chargers, it was a small docking station and you put your phone near it and it just starts charging with no wires between the docking station and the phone, they were reporting that they were also building a pilot house with all wireless electrcity throughout, dont ask me how that is supposed to work cause i still cant get my head around it, but it is out there and being worked on. dunno how safe it will be as well with all this radiation in the air. probably cause more cancer and other illnesses !!


just found this

Yes it is working fine if U are close enough.

But it is far from running a Tellie :)
 
Computer says no so far. :confused: ;)
 
Induction, that's what it is... :D

Basically, if you take a transformer like what you use for a charger for your mobile, you have 2 windings around a ferrite (I think) core, 240v in and say 12v out, if you split the two so they can be seperated, then you get "wireless" electricity, you don't need electrical contact in order for the devices to be powered, therefore wireless electricity isn't that difficult... :)

OralB have already done it with their electric toothbrushes, keeping the base and the brush electrically seperate in order to prevent any splashes of water shorting the charger out... :)
 
M8, you know your stuff. ;)

I only worked it all out from that Toothbrush actually... :D
 
My OralB toothbrush is just like that, I bought it when they first cam out about ten even 12 years ago and was also facinated as to how it charged up. I did not need to take it apart as the Israeli airport security people did that for me in an effort to make sure it was nothing dubious. It has never been the same since.

Another example of this is to take a fluorescent tube 3 4 5 or 6 foot, does not matter, then walk under the High voltage grid cables that criss cross the landscape and watch the tube light up

Yep, oralB toothbrushes were amazing when they came out with that unique charger, but as for airport security taking it apart thinking it was something suspicious, what numpties!!! :-rofl2

As for Fluo tubes, I've never tried that, but someday I'll take a walk with a tube and watch it light up under the cables!!! :D

:) Maybe we should all move to houses under power lines. Run all the electrical stuff for free. May even be able to get the missus charged up a bit to liven her up at bedtime.

If the missus isn't working properly, try finding something of hers beginning with G and ending with Spot.... ;)

Don't think that's induction, more likely to be the electrostatic field causing the tube to strike.

Not really bothered about the name or the physics involved, it lights up without wires. ;)

Yes the static may make it strike as with a standard starter but the static would dissipate and therefore it must be the EMR keeping it lit

Not even radiation, but the potential drop from 500kV at 100' up, to zero potential at ground level. Across a 6 foot tube (and maybe a 6 foot carrier with virtually no resistance). About 60kV in my calculations.
