There is a strong tendency for people to state that such a system is not possible since it contravenes the Law of Conservation of Energy. It doesn’t. If it did, and any such system was shown to work, then the “Law” would have to be modified to include the newly observed fact. No such change is necessary, it merely depends on your point of view.
For example, consider a crystal set radio receiver:
Looking at this in isolation, we appear to have a free-energy system which contradicts the Law of Conservation of Energy. It doesn’t, of course, but if you do not view the whole picture, you see a device which has only passive components and yet which (when the coil is of the correct size) causes the headphones to generate vibrations which reproduce recognisable speech and music.
For example, consider a crystal set radio receiver:

Looking at this in isolation, we appear to have a free-energy system which contradicts the Law of Conservation of Energy. It doesn’t, of course, but if you do not view the whole picture, you see a device which has only passive components and yet which (when the coil is of the correct size) causes the headphones to generate vibrations which reproduce recognisable speech and music.
This looks like a system which has no energy input and yet which produces an energy output. Considered in isolation, this would be a serious problem for the Law of Conservation of Energy, but when examined from a common sense point of view, it is no problem at all.
The whole picture is:
Power is supplied to a nearby transmitter which generates radio waves which in turn, induce a small voltage in the aerial of the crystal set, which in turn, powers the headphones. The power in the headphones is far, far less than the power taken to drive the transmitter.
The whole picture is:

There is most definitely, no conflict with the Law of Conservation of Energy. However, there is a quantity called the “Coefficient Of Performance” or “COP” for short. This is defined as the amount of power coming out of a system, divided by the amount of power that the operator has to put into that system to make it work. In the example above, while the efficiency of the crystal set radio is well below 100%, the COP is greater than 1.
This is because the owner of the crystal radio set does not have to supply any power at all to make it work, and yet it outputs power in the form of sound. As the input power from the user, needed to make it work is zero, and the COP value is calculated by dividing the output power by this zero input power, the COP is actually infinity.
Efficiency and COP are two different things. Efficiency can never exceed 100% and almost never gets anywhere near 100% due to the losses suffered by any practical system.
