Save the Earth! From evil parasitic power packs...

Ralf Maximus:
Via SlashDot comes this press-releasy kind of article:

New technology allows Fujitsu Monitors to consume zero power on standy

Basically, they use capacitors, a small solar array, and old-school relays to restore your monitor after it goes to standby.  Aside from an audiable "click" as the relay triggers, there's no difference in user experience than what we have now.  And it draws zero AC power while asleep.  Cool.

It's about damn time.

Now, consider this... if you were to walk around your home/office/cell and switch off every electronic device you own, how much power would you still be consuming?

Don't forget the little black power-packs plugged into the wall for recharging your phone, Ni-Cads, and everything else portable.  What about your stereo system, with it's lying green "Off" light?  Or your big-screen TV?

Add it all up and I bet it's MORE than the 8% average quoted in the article, since you -- dear reader -- probably have six times as much electronic crap than the average human.  Without conciously meaning to, we early adopters of cool tech are wasting more power than the rest of humanity.  We should probably keep this quiet lest they notice -- pitchforks and burning torches are easily understood low-tech for the masses.

So what can we do?  Let's talk about those evil black power supply bricks first. 

One idea I had: How about a small device that plugs into the AC socket *between* the device and the wall?  It would look like a single-socket foreign AC adaptor with prongs on one side and a plug on the other.

On top of the device would four small buttons: ON, OFF, SMART, and LEARN.

ON and OFF are self-explanitory (I hope).

LEARN mode is used when the device is first plugged in with a host power-brick.  Plug the whole assemby in, then connect your brick to whatever device it needs to power such that it's drawing a full load.  LEARN mode makes a note of the current demand made on the AC socket side of things.

Once LEARN mode does its thing, switch it to SMART.  Thereafter, whenever the brick draws less than the current threshold previously LEARN'd, it shuts off power completely -- basically OFF mode.

After that the user must manually tap the SMART button to reactivate the power.  Sure, it's an extra step and may be inconvenient if your AC adaptor is behind a 500 pound piece of furniture, but this is FOR THE PLANET, DAMMIT!  Also, it won't be applicable to devices that must always be on (medical equipment, security alarms) but for most of the consumer goodies we have it would make sense.

Package the device in garish blue/green eco-friendly recyclable card-stock (pictures of lush green meadows and hippies optional) and label it EARTH POWER DEFENDER (or something) and sell them for $9.99 a piece.  We'll make a fortune. 

So...  who around here can work a soldering iron?

iphigenie:
The danger with your idea is that say you turn the dvd player off but still play the radio, it is likely to shut it all down. But I like it nonetheless, it just might work...

Although considering that there are master switch systems which turn devices off when the master is turned off, all we need is a way for a pc to be able to shut itself down when it has idled long enough - and with the hibernate-to-disk options we have it could still resume quite quickly. I think that can probably be achieved today.

The problem is, many devices just dont want to be turned off.

I have a small stereo which does not have an OFF. It is either on, or on standby. Or unplugged (which is what i do). I find that silly, i dont think an on/off button is that expensive that it couldnt be put on a £100 device...

My cable box is the same.

I turn things off at the wallplug quite a lot but I must say my cable box doesnt seem to like it - it takes a longer and longer time to restart every time and usually freezes several times prior to working again. Its like they designed it thinking it would never be turned off.

iphigenie:
Oh and I wish there was a cable modem with wake-on-lan... so it can turn itself off and then back on when you use it again.

Is there one? I just have the cable modem that came with my ISP kit so I never looked at the market much

Renegade:
There are SOOOOO many energy saving technologies out there that aren't being taken advantage of. Patents create part of the problem, but you've got to recover R&D costs...

Availability is another problem. Then there are technologies buried by vested interests.

Then there are "eco-friendly" technologies that are anything but - they damage the environment more than they help.

I'd love to get in on a business that genuinely made a real positive difference. The idea sounds good - but I don't have the necessary expertise for electronics design.

I could probably find a decent manufacturer (but not in China - that's just asking for the product to be stolen).

Getting media attention for something like that would be simple - they're always up for a "green" product.

Ralf Maximus:
I was thinking the widget described above would be for "dumb" power transformers, that one plugs in and forgets about, whether they're actively being used or not.  Some devices (as noted by iphigenie) wouldn't like being shut off from main power; those I recognize as being a necessary evil.

But those wee little black power bricks just piss me off.  Individually, they're nothing... but add together 10 or 15 of the beasties and you're talking about some serious current, all going to waste.  Multiply by a few million households and I bet we're talking some serious power waste.

I am reminded of a similar technology marketed about 10 years ago called the "Bulb Boss".  The devices were small ceramic discs the size of an American light socket, each containing a chip.  A disc went inside the socket, between the bulb and the contacts, and *did* things.  Some Boss chips would turn a regular 60-watt bulb into a dimmer, by regulating the voltage it allowed through -- one controlled it via the standard on/off switch, pulsing twice for "half power".  Another automatically shut off the power after an hour of use -- perfect for entry-way lights.

And all Boss discs increased the lifetime of their host lighbulb by x3 to x5.  They weren't expensive, and sold three-discs-to-a-package.

So why didn't they sell like crazy?  I'm guessing the economics were wrong (nobody cared about saving energy in 1996) and lack of marketing.  Such a simple idea, and quite effective, yet you can't get the durn things anymore.

One electricty quadruples in price, maybe someone will do something about the evil black power bricks o'doom.
