I admit, I'm lazy, but I like to invent things...

I see that the energy review suggests outlawing "standby" buttons on consumer electricals. Good thing too. Because if they're there, as they are in nearly all cases in my little hovel, they are going to get used. I don't know if they really drain as much electricity as they say, but am prepared enough to believe so and feel guilty about having them, however convenient they are when watching "Science Shack" on the TV at 3am to help me sleep (I mean - there's no point really if you have to get out of bed again and wake yourself up to switch the whole thing off, not for the uberlazy like me anyway).
But my TV and Hi-Fi are only a few years old, so they're going to last long after "peak oil" by the looks of it. So I was thinking, what would make it easier for me to do my duty and turn the bloody things off properly.
With computers you can actually turn them right off and still have them turned on remotely if they are on a network using fantastic sounding little things called "magic packets". The network listens passively (yes, I believe it does take a tiny amount of charge, but from the onboard battery rather than the mains if I understand it correctly) and when a magic packet arrives addressed for that particular gizmo it knows to turn the machine on just as surely as if you were pressing the button yourself.
So, for those of us who will have TV and other gadgets with standby buttons on for a good while yet whether they are outlawed or not, could we not have some kind of power plug that works with something similar to these "magic packets". One remote control could do for the whole house with different numbered plugs. Power the thing off at the wall and still be able to roll over in the morning and turn it all back on again without getting out off bed?
Anyone any good with a soldering iron want to have a go at it? Or point me to one someone made earlier?

computers do consume power when they're switched off, if you look inside you'll probably see a little green LED on the motherboard indicating that power is going to the board.
It isn't much, but I suppose like other things it mounts up.
Your idea is a good one though. You could use a long life battery (beta radiation as in pacemakers or a rechargable perhaps) to provide the small amount of power, battery technology is set to make some pretty big advances in the next few years.
Or, if you were very clever you might be able to power the switch-on logic from the remot- obviously easier if there's a wire though...
With anything like this, you need to watch the carbon (and other environmental) costs of manufacturing the product, but I can't see them being that high."

Okay, I believe you. My green light was on until I switched off at the wall. Hmmm.
So, a modification would do for me. Maybe not for every plug, but for every four-way power bar. They already have so much electronics in some of them - surge protectors, network protectors, telecoms surge protectors and so on.
But I'll bet a battery would be sufficient, assuming it could recharge itself when the power came back on.
Though I've never really worked out why they never used battery powered standby in consumer electricals. If you could achieve battery based listeners" in computers say, and combine that with persistent RAM for "hibernate" state, you could presumably create a machine that literally powers itself off completely every time you're away from it yet takes less time that the screen saver exiting to start up again."
