I'll rephrase the questions.
Have any of your devices shown more energy output than is input by you
either directly or indirectly ? Indirectly meaning as in by capacitive coupling to
other devices such as a power supply next to a battery for example.
In other words, input measured at the input terminals and output measured at the output terminals.
We all know that if energy comes out it must first go in in some form and from
some source, therefore OU cannot mean energy from nowhere, all it can mean
is extra energy out as compared to our input energy. Or in other words
over 100% efficiency means over unity. Unity being the energy input by us
matched by the output as useful work. If any losses are involved in a system
showing equal input to useful work output there must be energy input from
another source. A system showing a total efficiency including all losses would
account for 100 % of all input.
Total efficiency is always 100% because losses are accounted for, energy
cannot be destroyed, working efficiency can be less, because losses are not
considered as output and compared to our input. If extra energy from outside
the circuit is utilized the total efficiency is still 100%, but the working
efficiency "could" be over 100% because all useful work output is compared
only to our input, the extra output would need to exceed the losses though
or the working efficiency would still be below 100%.
