Another snake-oil merchant. There seem to be quite a few these days. "Just watch my magic meter and see how much money it can save you". This one seems to work by filtering out the startup surges that occur when appliances such as refrigerators, air conditioning compressors and other motor-driven things turn on. As if this would save the consumer anything at all. A waste of money.
Whenever there is a surge in concern about a certain everyday cost, such as gasoline or electrical power, products like this pop up to cater to that concern. Do a web search for "gasoline saver" and you'll find similar fringe products.
If all the brain power that goes into coming up with these combined products was put into real solutions, we'd have one really cool product out there that would save us all a ton of money!
If the product maker really thinks it works, they should give away a couple hundred of them and let the word get around. Now there is a marketing strategy!
The only thing that this can address is power factor and demand as would have been alluded to by the reference to spikes. Is power factor a real issue with a home? I have never seen any studies or concerns as to it being an issue. Current spikes? I would imagine that there are quite a few. But what percentage of the overall power used do spikes represent? I would conclude that it would be insignificant at best. And demand certainly isn't an issue with residential power like it would be in an industrial complete where you are kicked up a notch if your power demand exceeds a given level. So one must conclude that this is a more modern version of a snake oil salesman.
Here's a quote of what I tried to post to the youtube message board for the x-power site.
This is nothing but a power correction capacitor- it may reduce peak current as measured on a clamp ammeter, but is going to do NOTHING to reduce overall power consumption as measured on a typical residential home kWh meter.
Marketing this towards industrial users who have more complex meters and are charged per power factor is one thing, but marketing this for home use on the claims that it will reduce electric bills is completely fraudulent.
SURPRISE, he moderates comments. Guess my comment there isn't going to show up, nor are anyone else's.
