Can you believe it?

They show before and after electric bills and everything!

Great day to be alive!

It's on the Internet, so it must be true.

I hope your being sarcastic jwax! :roll:

This scam has been going on all over the world!

You can even find the dumb things at WALMART!

Here's a Video of one being disassembled: https://www.youtube.com/watch?v=KXRmdDAWHMg

Just a power factor corrector and not a very big one either. That youtube video was very good at explaining this product and its shortcomings

Seems to be an incidence of taking real engineering theory and misapplying it to a situation to make money. Most inductive appliances already have PF correction built in, just look in any ceiling fan, the same black box caps are used.

PF Correction is mainly applicable in heavy industry where the reactive power though not measured, if significant can still cause resistive losses in the conductors which is not returned to the utility.

The truth is that it is a little ..well maybe just a bit true. If it does power factor correction the average home really doesn't need or will benefit from that. Big industry, shopping centers, factories, with large inductive loads will benefit from that, and, the power company puts those capacitors right on the line outside. It's nearly impossible for a homeowner to determine any potential benefit from gadgets like this since too many factors are in play month to month that affect the bill. It's like the letters I get from our utility company yelling at me about how much energy I used compared to my neighbors. The nearby homes are different size, age and construction and best of all are mostly unoccupied all day long. I am home, run a business and drink coffee all day...To the bean counters, numbers are numbers. So this is just another bucket full of prop wash!

Wow, I didn't think everything can be resolved in such a simple way.

PF Correction is mainly applicable in heavy industry where the reactive power though not measured, if significant can still cause resistive losses in the conductors which is not returned to the utility.
This is because of uneven distribution of current over the cross section of the conductor leads to a significant reduction in the cross section of the actual current-carrying part of it and, consequently, to an increase in its active resistance.

If you are referring to the skin effect, I think that is negligible at 60/120 hz.

Methinks this 'skin effect' is when the purchaser...Gets Skinned! :razz:
