Earthwise Power Saver

I just saw the introduction of Earthwise Power Saver on Today Tonight. If it is true that it can cut down up to 35% electric usage and also drop electromagnetic radiation to acceptable level, then it is something worth to install even it costs $1300 to $1700.

Welcome to Earthwise Power Savers

Power saver (Channel 7 Today Tonight on Jan 31, 2011)

"The technology has been around for approximately 30 years and it was first invented in Germany but it wasn't really needed then because power prices were really cheap," Mr Hourigan said.

It's called the Earthwise Power Saver and Geoff has adapted the German technology for Australian conditions.

Essentially, it is a device that controls the flow of electricity to appliances so they get the right amount rather than too much, and the savings it can generate are up to 35% of your electricity costs.

"At the moment power is coming into your house all static bumping up and down, but after the Power Saver is installed it is just a clean, true line so it will actually run cleaner, cooler and last longer," Mr Hourigan said.

Independent testing so far shows promising results. Electrical engineer Greg Paxton has worked with the CSIRO and federal and state governments which are interested in the Power Saver’s potential.

Greg's very optimistic as he has seen the clear evidence that it actually does work. He claims anyone can see that it reduces the current used by the apparatus which is consuming the power.

Internet based Panacea University electrical engineer Ashworth Palise agrees.

"In my opinion, it has shown successful results. It works," he said.

Geoff is meeting with Queensland government in the next fortnight and has already installed 300 Power Savers into private homes and is anxiously anticipating their next power bills. The Power Saver also cuts down electromagnetic radiation which all electrical appliances emit and have been linked to cancer.

"A lot of people know it as dirty power. When we turn the Power Saver on and [electromagnetic radiation] will drop to the acceptable level of dirty power that should be in your house," Mr Hourigan said.

Depending on the size the Power Saver ranges in price from $1,300 to $1,700 installed. Geoff believes the unit will pay for itself within two years and guarantees it works.

"We'll give you your money back or we'll test the unit to make sure the unit is working first."

If these units are just a power factor correction device they don't save you any money as in australia residental users get billed for kwhr not vahr.

Hmmm, W = V * A. Then kwhr and vahr measure the same thing.

I am not an electric engineer. But I think whether this power factor correction device can save electricity usage or not should be easy to test. I think that the tested object (TV, computer, light bulb, AC, cooker, oven, etc.) will affect the result.

This company claims that they did the test in http://www.earthwisepowersavers.com.au/case.html.

Well, I do hope to see the test result by the 3rd party.

What's the difference between W and VARs? Not by the formula? I am kind of confusing now.

Where the hell is the ACCC, also few years ago Choice did a report..its snake oil the Power Factor Correction, in any case Domestic customers only get charged in Watts (W) Real Power not VARs (VoltAmpsReactive) Apprent Power!

Wrong! Power = Volts * Amps * cos(phase angle)

That simplistic formula you quoted ONLY works for a resistive load.

When dirty power is fed into smart meters they misread the amount of power being used. These were large errors of up to +582%:

PF corrections cleans dirty power and would result in lower readings (aka lower power bills).
