A few things should be self evident..

Machines that attempt to use only gravity as a source of energy dont work.

Milkovic's explanations of what is happening in a 'two stage oscillator' is completely flawed.

The energy to bend the beam in the children's swing comes from absorbing some of the energy of the fall of the pedulumn. The beam stores this energy as strain and return most of the energy to the pendulm as it flexes back.

Any attempt at extracting energy from such devices is pointless.

LibreEnergia,

Your make a clear representative statement of the status as relating to conservative systems as we know it today.
It is somewhat absolute, over-assumptive, excluding and negative.  On the same level as the ongoing ranting of the 3 musketeers (MarkE, TK, MileHigh), let their explanation be correct, but most of the time, phrased in a un-constructively and terminal way.

I can not believe that you would think there is no backdoor that possibly could be unlocked by a new material discovery, technology invention, a new knowledge, a new science field that would provide a key to unlock that door.

PS: Their is no other disagreement.

So where is the evidence of the elusive back door?  If one wishes to convince others that there is a pony in that closet, some evidence would be nice.

Zeit,  what is the point?

Strange things are going on! That's my point and that puzzles me! Because ...

... when textbooks do not comply with reality, then the usual way of science is to adjust reality to the textbooks (so there is no need to print new ones) instead of doing it vice versa. Such as saying it won't work, when the entire world can clearly see, that it does work indeed.

Another example (slightly off-topic): A crystal-radio can't work without free energy. The amount of energy that it receives by a small antenna (coming from the transmitter miles away) can never create any noticeable sound in an earpiece. This can be calculated clearly (the transmitter would need to have some megawatts of power otherwise).

Hence, how does a LC circuit actually work? Wikipedia: »The parallel LC circuit connected in series with a load will act as band-stop filter having infinite impedance at the resonant frequency of the LC circuit. The parallel LC circuit connected in parallel with a load [crystal-radio] will act as band-pass filter.«

That means, when we tune the crystal-radio's LC circuit to the transmitter's frequency, the LC circuit is in resonance and the LC circuit's impedance is infinite for that frequency, whereas all lower frequencies (received by the antenna) are shorted to ground through the coil and all higher frequencies are shorted to ground through the capacitor (illustration a).

But this implies (illustration b) that removing the LC circuit completely should result in having infinite impedance for ALL received frequencies, thus we should hear all nearby transmitting radio stations at once, but we don't. Why?

Because now we don't have the energy amplifying feature of the LC circuit anymore!?

So, who is willing to adjust this reality in order to comply with the textbooks?

This is a fail on so many levels it is difficult to choose where to start.
Broadband energy summed together appears to an indiscriminate receiver as noise.  The tuned filter discriminates energy within a narrow band.  Impinging energy within that band passes on to the output at a small loss.  Crystal radios work because the human ear can detect pressure variations of 1E-9 BAR.  It does not take a lot of power to make sound that is audible in headphones.
