Save $$$ off your electrical bill by filtering and conditioning electricity for inductive loads

Hello Sterling!

Stan Macdonald would make an interesting interview guest as he has a number of energy devices, including the Power Saver described below.

Presently, there is not a website that catalogues Stan's efforts through his organization, "Global Solutions Educational Services" but that is forthcoming


When transported, electricity is subject to numerous fluctuations and losses of charge as wellas to undulatory variations leading to electricity peaks which can cause damage to your electrical devices. Thus, a part of the electricity delivered to our households is delivered in the form of unexploitable overcharges, yet we are billed. These electricity peaks make us consume more and pay more, especially if most of our consumption comes from inductive loads, rather than resistive loads.

Q What is the difference between a resistive load and an inductive load, like a computer power cable's transformer?

Resistive Load: An electrical load which is characteristic of not having any significant inrush current. When a resistive load is energised, the current rises instantly to it's steady-state value, without first rising to a higher value. An electrical load in which voltage and current are converted to energy in the form of heat i.e., an electrical heater, incandescent bulb.

Inductive Load: An electrical load which pulls a large amount of current (an inrush current) when first energized. After a few cycles or seconds the current "settles down" to the full-load running current.

The time required for the current to "settle down" depends on the frequency or/and the inductance value of the Inductive load

Apparent Power vs. Real Power:

The Power Saver from "Global Solutions" can save from 20 to 50% without changing your usage habits by optimizing the voltage and current according to the need. It acts as a tension stabilizer by storing more than 10 seconds of energy and thus delivers a constant voltage, even during a temporary tension peak. Thanks to this regulation, the lifetime of your electrical equipment is also improved.

110 volt plug in version of the Power Saver $150 + shipping

220 volt whole house version $300 + shipping

Calculating Power Factor

Note: open4energy has read the linked reports in full. There is an error in the explanation which needs to be noted:

Real Power - stated in Kilowatts is described as being Volts x Amps - This is not correct - this is the definition of Kva - volt-amperes

For the studies to help us understand the data, we would need the power factor reading during the respective periods of testing.

But, it is not unexpected that the electricity bill remained unchanged by power factor correction. Delivering 1000Kva at 100% power factor for one hour results in billing of 1 Kwh and delivering 2000Kva at 50% power factor for one hour results in billing of 1 Kwh.

Yes the utility suffers for delivering 2000Kva and having 50% returned to them, but they only lose the distribution costs not the energy. Electricity is a wave energy, not a physical energy.

Consumers are billed on Kwh - the same in either case above - with correction and without - hence the NO savings in the electricity bill for consumer power factor correction!
