This post is about some fun cases of static piezoelectric structures.
Lets imagine some static large tall truss farm structure (like transmitter towers).
Also lets say it is axisymmetric and heavy enough to create high loads on lower levels.
Lets attach to deformable trusses a special piezoelectric elements (just same as in the piezolighters) with the ability to create electric charge at both compression and stretching. They are all wired to some electric grid.
Additionally lets install some wind stopping load on the top of this installation (let it be some large cube).
Since the structure is axisimmetrical and is loaded by wind randomly, so all the trusses with piezoelements will experience random cycles of
compression and stretching.
With each cycle they will produce some electric charge which can be gathered and collected in attached electric grid.
So in general we can get an infinitely scalable power generating structure, just increasing the weight of structure and number of piezoelements.
Does that means it is a kind of almost infinite energy source, based on gravity and the forces of support reaction from planet surface ? Is it a conversion of gravity to energy, or just something else ?
Also lets imagine a planet/satellite (like Moon or Mars for example) and built in very large structures on it like these ones, generating power and sending it to some remote location. What about the law of energy conservation ? Where the energy is taken and what will happen to that planet in time – will it slow on its orbital movement or something ?
I guess there is some kind of logic/physical paradox in these ideas, but just can’t find any obvious mistakes in it. Could you please comment it ?
