Not sure... SNIP

I'm sure the Professor will have some input on this, looking forward to it.

The Intelliworks Energy Saver Unit reduces the amount of power drawn from the utility by storing (in its capacitors) otherwise lost and wasted electricity (watts) caused by the inductive appliances in your home.

Read the above several times. Does it really make any sense?

You can charge a capacitor from a power source and use that stored power to give a kick start to an inductive device. Without the capacitor some of the power used to get the device moving is dissipated as heat, which is not a needed form of energy.

Unless you are constantly stopping and starting large inductive devices that the manufacturer has not properly designed, this device would be redundant and un-needed. IMPO, the inductive devices in a residence and RV are already designed for optimum energy use.

The energy stored in the advertised device's capacitors comes from the utility to start with - which you pay for. The concept of an add-on device such as this actually reducing the power consumed by an inductive device to the point of saving enough money on ones electrical bill to justify the cost of the device(s) is unlikely.

My vote is Snake oil :)

I always wanted to "run the numbers" on this one as far as would it be practical to use power factor correction in a residential situation? Common sense tells me it's a waist of time but it is used quite often in manufacturering plants. They, however, use muliphase power and usually have large inductive loads.(electric motors).
The question is what is the common range of power factor numbers for a standard home running single phase 220? .7 - .8 might be worth it.
Hmmmm...Maybe create some type of chart or graph......
