Electricity flow control devices

Paul/anyone.....Paul mentioned in a post a week or so ago, a device
that can be installed in a house so that there is only electricity
in the wires when there is demand. What is the name of this
device? Wld a standard electrician be able to help with this? Are
they expensive? Do you need to have a modern 'breaker box', or can
it be fitted to older wiring setups.

Also can you explain a bit how it works? How does the device "know"
when there is demand?  

I am thinking of having one installed at my mum & dad's house, where
i stay sometimes. I have to use so much metal shielding material
to protect me from the mast opposite their house that i have to
switch off the electricity. They have been incredibly
understanding, but it causes alot of tension especially with my dad.

So how does the device work? If my dad, for instance, left a
bedside lamp switched on at the plug but switched off on the lamp
itself, would the device count this as demand? Wld everything have
to be switched off at the plug? Perhaps it doesn't work like this
at all?!!
help!!!!

I don't know if you can get them in the US. They use a low voltage to
detect a load and
if there is one they turn the voltage up full. Here's link to one:

thanks paul and bruno. Bruno, i'm in UK. thnks for the link, they
are rather expensive and i didn't realise one needed one for
everyroom, i thought it might be done centrally where the electricity
comes into the house. I've book marked the page and will have a
think!
