Light up your home enirley with LEDs.
Would this save ony money?.. apart from looking pretty cool, LEDs are supposed to be pretty low power users right?

LEDs are much more efficient than filament lamps and have now reached the quality where they also provide a significant light output to use and not just indicate. White and Blue are the latest colours to become available - for the last 20 years the limit was red/yellow/green.
BUT they are low voltage devices (2~3v) so significant technology is needed to provide the appropriate power derived from 230v supplies.
Low voltage supplies are much safer to handle, so the wiring requirements are much safer PROVIDED the derivation foirm 230v is appropriately isolated.
Installing loads of lights still means loads of wiring, whatever voltage is used; there isn't yet an effective means of 'radiating' power - well, if you leave out microwaves as used in mobile phone systems and the controversy that raises.

radiating power... mmmmmmm sounds like something out of the Simpons, just a a few neuclear isotopes in the cellar, everything runs for free, probably wouldn't need lights anyway, there would just be a soothing green glow around the whole house.
You're right tho' all these wires, they managed to to get rid of them for computers, handhelds, but thats a pretty big battery for the house, no?
Microwave power is too dangerous as you say.. there's a telecom tower in Amsterdam, as you drive past, all radio, mobile signal is lost for a radius of about 300meters. I tr not to look at it, and hope the sheilding effects of the car/cage I'm in will sheild me.
.
So YAY for LEDs, but BOO for still having wires. (now there is a money spinner)

what happened to the neuclear battery? last time was in the news about some old soviet peices found by common folk and someone got burned/ time before that there was a short blurb in scintific american indicating that it had come recently off classified status. seem like a good idea but dont know what power range may be probable; any ? any answers ?
