Welcome to the forum.
Energy meters measure current and voltage, that is, they have both a current input and a voltage input.
The reading is based on true KW, not assumed KW based on current.
As the energy meter measures KWHrs, and the KW consumed will not alter with the addition of power factor correction, there will be no advantage in adding power factor correction unless you pay an additional maximum demand charge, or a PF penalty.

Welcome to the forum.
While the theory and examples of this technology may look convincing to some, I for one see this as power factor correction on a domestic supply and if this is what it is, then you will not reduce the KWHrs used and therefore not reduce the domestic power bill.
Power factor correction has been around for a long time and it has been proposed as a means of energy saving on many occasions.
The bottom line is that power factor correction will reduce the line losses, but not the KW consumed by the load.
If the supply meter is based on current rather than KWHrs, then you will possibly see a reduction. If the meter is based on KWHr (which is the norm) then you will not see a reduction.
Additionally, the domestic power factor is generally pretty high which is why the supply authorities do not monitor and charge for PF or KVA usage.

Experiment one shows no change in Watts.
Experiment 2 shows a 0.8% INCREASE in Watts.
Experiment 3 shows a 0.5% INCREASE in Watts.
Experiment 4 shows a 0.9% DECREASE in Watts.
If we take the best result (Experiment 4) the load without the device is 449W and without is 442W thus a reduction of 7 W. In my part of the world we pay around 15c/kWh. If our device runs 24hours a day 7 days a week 52 weeks a year we would save a whopping $9.17 per year. Most of my customers find a 2-3 year payback acceptable so if this device costs around $25 AND my devices runs constantly then it may be a viable option. Or I could just switch it off for 20 minutes per day.

I have just noticed Experiment 5 but it seems around the same as Experiment 4 so my view does not change.

It never ceases to amaze me...
One of these days I'm going to release my "Patented Sure-Fire Watt Stopping Power Miserly Energy Reverserator"
Here's a picture.

"But act now and enter our super secret discount code "foolhardy", and we'll knock off 3 of those payments!
Call now, operators are standing by! This offer expired 4 days ago, but by special request we have held it over, just for you! So ACT NOW!"
Just because the subject of this thread is more directly linked to residential energy savers, here is some interesting information I posted in another thread.

D'oh! Just read your earlier post pointing out the same thing kens. Sorry, didn't mean to try and steal your thunder...
Great minds think alike I guess.
