Simple to build isolation transformer that consumes less power than it gives out

[Jack Noskills]

I have proven this to myself using watt meter and bulb in two trafo test. But maybe watt meter is not good for measuring inductive loads, don't know. Maybe light bulb passes more power so that its brightness does not increase.

How many minutes you think it would take for a skillfull person to do a measurement if suitable equipment is available ? Five, or maybe ten ? If this is considered to be a waste of time then so be it.

I am trying to get a second opinion, makes no sense to debate over such a simple circuit. What matters is the results only.

Fine, but you are missing the point;

You have NOT had confirmation of OU results from any other party, yet you continue espousing that it is indeed OU.

You have NOT proven this to yourself beyond reasonable doubt; you are only speculating that it is OU based on your poor measurement equipment and method.

Ask yourself this: Would you bet your house on the notion that your circuit produces OU? No, I doubt very much you would.

I would however bet my house that your circuit doesn't, even without testing it.

I don't have the patience to read through all the posts.........

Did anybody notice that this configuration is just a plain auto-transformer?  For a 1:1 winding ratio the output voltage will be half of the input.

yes, look at my post:

This comparison picture shows that setup is exactly the autotransformer. I have noticed that when coils are of different length then it consumes power. But when coils were of equal length my wattmeter did not show any change and lamp was not lit at first trafo when I did two trafo experiment. Also tuning cap made output brighter. Load taken at output did not ahow anything changed at input and this made me think there is something going on. First I did the two trafo experiment, then one trafo and results were similar. In one trafo experiment when capability of the core was exceeded only then power was being used from source. If coils were of unequal length then power was always consumed. So this was it in a nutshell.

Current status is that several replication attempts have been made but they did not show anything special for various reasons. Most important is to use windings of equal length and impedance must be high. If anyone can try using secondaries of MOTs that are similar then that would be great. Alternatively any low power iron core stepdown trafo can be used and take secondaries from them and combine as 1:1 trafo. I used 20 watts laminated E-I iron trafos.
