ten thousand tuning forks all spaced an inch or so from each other in a grid. If you got one going would the rest vibrate as well? i imagine it
something like dominos. Or if you had a small stimulus vibrating only one in a constant state would it essentially power the rest? And could that
energy be harvested? Maybe with this newly invented microphone. I don't know much about physics, but i like thinking of ideas. So anyone have a
thought or response on this on why it would or would not work.

It is possible to set up what is called a "cascading" resonance, where resonance will travel from one vibrating object to another, and then back
again.
However sound waves, just as RF waves and even light waves encounter, is resistance. The air itself is a resistor. An example of that is moving away
from a loudspeaker, the further you get away from the loudspeaker, the attenuation of the sound increases, thus the amplitude of that sound
decreases.
So with the idea of setting up a bunch of tuning forks in a room so they react upon one another, eventually the air in between each tuning fork will
attenuate the sound wave to a point where it no longer has as much resonating influence on its neighbor, eventually the whole thing comes to a
stop.
Something either has to eliminate the resistance so the sound wave remains pure in amplitude, or something must sustain the sound wave to overcome the
resistance.
As I have mentioned earlier, as did another member, a crystal radio is an example of free energy, taking exsisting RF energy which is modulated and is
AC of in itself, can electrically act upon a pizo element, or earphone and you hear sound. But this energy received is very weak and the components of
the crystal radio itself has resistance. The diode used in such a set, or any semiconductor junction be it PN or NP, has about a .7 volt drop across
the junction, which means for 1 volt passed through the diode, there is a .7 volt loss within the junction itself.
Newer PN/NP semiconductor materials with less impurities have dropped the loss down to about .4. Those PN/NP junction components however are extremely
expensive and usually used in special applications, research etc.
Your best bet is to work with super conductors, which at the appropriate temperatures, has no resistance to electrical flow. Eliminate the internal
resistance of the components, or the ambient air for your enclosed room filled with tuning forks, you might actually overcome the barrier that keeps
perpetual electric flow from occuring. If that can be accomplished, you simply stack the elements to increase the output, and then you might have a
workable power source that can drive a practical load.
