Funny, the XFactor FAQ states pretty specifically that XFactor is a power correction capacitor.
I'm not interested in purchasing your product, I'm merely looking out for my fellow consumers. I'm an electrical engineer working commercial electrical systems, well aware of the purpose and function of power correction capacitors, and frequently use power factor correction capacitors far larger than the xpower plug-in model. I'm well aware of why and how it reduces measured current. What's clear is that you don't understand how your product works, and are lying to consumers if you persist in claiming that a power factor correction capacitor (with some small harmonics filtering) is going to have ANY impact on a residential electric bill. Not to mention that a typical residence already has a power factor of close to 1; if it didn't, you'd quickly overload and trip the 15A or 20A breaker on the receptacle circuit you plugged your capacitor into. Funny that the demo uses a large unloaded motor that you're not going to find in a house and that gives an exagerrated power factor- why not repeat that demonstration with a loaded garage door or garbage disposal motor so you can show the fraction of an amp difference for the 5 seconds it's on? Or with the purely resistive loads like hot water heaters, ovens and clothes dryers where it will have 0 impact?
By the way, Watts = Amps x Volts is false when talking about AC and power factor. The true equation is Watts = Intregration(Amps(t) x Volts(t) dt.) Or, for constant power factor: Watts = Amps x Volts x cos(phi). Placing a power factor correction capacitor on a circuit like this will decrease current and phase angle, but total kWh at the meter won't change. Since residential meters measure kWh (as opposed to kVAh), XFactor will make NO difference in the bill. In fact, it will actually increase bills by a small amount, due to internal resistance and leakage current in the capacitor.
