I have been a licensed electrician for nearly 15 years. Quite some time ago I was working for a home owner doing a large renovation along with several other contractors. Everyone has several power tools running nonstop (drills, saws, lights, ect.)
After working for a few days I had stopped to check the electric meter to ensure everything was ready for inspections when I noticed that since I started the job there was only 1500 watts used over several days. I began to wander how could that be? With all these power tools being used it should have been WAY more than that!
I then asked the home owner if he had ever had a problem with his meter properly reading his usage. He first laughed a little which I thought was odd. He then showed me a device that he had plugged into the wall. He said it was called an EcoWatt and it would decrease the amount of energy wasted due to the dirty signal that comes into the home from the power company. He said he had discovered if while traveling overseas and brought a few of these devices back with him.
I was very skeptical of what he was telling me. I had never seen or heard of something like this in my entire life so I began doing some research about the theory behind it.
After hours of research I found an article that explained how and why this theory works as well as why the power companies won't let it go main stream.
How Does It Work?
Quite simply, this is a device that you plug into the outlet closest to your breaker box. That is all you need to do, once plugged in the green LED indicates it is powered on and working. I did notice with further testing that if your home is large it is beneficial to place 1 unit close to the breaker box and another as far away from it as possible. It was as simple as that.
With my schooling you learn that appliances always draw more power than they need to run due to inefficiencies and noise on the sine wave. The EcoWatt reduces this noise therefor decreases the amount of electricity wasted. It does not change what the meter reads or steal extra power from anywhere, it just uses the energy more efficiently therefor needing less of it.
