Hmm...I would chose the Plugwise products over this any day. Has automatic stand-by killer included, without explosive effect, plus ability to create schedules, and to see what your devices are costing you in terms of electricity and costs, plus showing you your savings over time. Less gimicky = more effective.

It wouldn't make too much sense to pop the plug out using a spring. All you are aiming to do is cut the trickle power, so why not just use a solenoid to cut the electrical power to the primary device, without physically ejecting the plug?

no way I would use this for anything in my house. most things I know of have a timer or a clock on it that always draws and I would be really hacked if my coffee pot was unplugged right after making the coffee. the only thing I use that I unplug is my toaster and I don't need this to unplug it.

I used to get Mother Nature when was in Canada; always had very interesting issues, even ideas to build something for home, now I am happy again back into Mother Nature. Many things already knew, just come into a reminder again. A.Oscar
