A credit card size of '' Eco harmonics electricity saver card '' when place on the incoming power supply box will save 20 % on electrical bill. Can any person explain to me how it work ? Thanks and Happy New Year to the electronic group members .
It probably doesn't work. If it was a strong magnet and you had the right type of meter it could slow the meter down - but it is highly illegal, that type of meter is disappearing and you have a huge probability of being caught.
We have failed to address the fundamental truth that endless growth is
impossible in a finite world.
A friend of mine just sent me a video that showed how to make a free energy device. It was a diode bridge with a length of wire to serve as a small (2-3 inch) antenna, nothing more. Hook it up to a DVM, and - magic! - you get voltage. And volts are electricity, so you're getting free electricity. For $42 they'll send you instructions on how to make them.
The frustrating part is that if I point out how dumb these ideas are, people consider me just a spoilsport, a wet blanket trying to squelch these wonderful ideas. And don't even get me started on "zero-point energy," over-unity devices, and so on.
It's bad enough that so many people fall for so many of these scams - and have been doing it for millennia. Worse yet, there are all sorts of people out there who honestly believe what they're saying.
Has anyone ever seen the Hulda Clark zapper, that cures cancer and everything else? It's a basic 555 square-wave oscillator circuit. Who know it would be so easy to conquer all disease. Hulda Clark, by the way, is dead, so I guess the zapper doesn't confer immortality.
If you think you have the solution, the question was poorly
It only works when there is no artificial light, and its ambient = temperature=20 must be maintained close to the outside temperature. Its performance is = also=20 degraded when it senses sounds and vibrations and EM radiation. So you = must=20 turn off all electric lights, heating or air conditioning, and = electronic=20 entertainment and communication devices. Then, it will save you at least =
Folks are starting to build stuff (or at least IC companies are making money selling chips) that do the sort of ambient energy harvesting that you're talking about for seldom-used light-duty chinguses. Sort of like the "eternal clocks" that were popular in the 1950's and '60's that ran on temperature or barometric pressure changes.
