Piezoelectric electrogenerating footwear

There is an another fun useful application of the piezoelectrical phenomena.

Lets take a look at common shoes. They commonly use elastic soles for a dumping moving effect during walking/running.

Imagine the same shoes, but with piezoelectric elements on its sole (just same as in the piezoelectric lighter) with the ability to produce charge at any type of tension – compression or stretching.

Along with dumping effect they will produce a lot of electricity when moving, which can be gathered and collected lets say in attached accumulator and used for example for charging phones and devices, lighting, etc.

Piezoelectric car tires

There is an another fun useful application of the piezoelectrical phenomena.

Lets take a look at modern car tires. They commonly use gas pressure to achieve elastic behavior for a car moving along the road.

Imagine the same wheels, but with piezoelectric elements (just same as in the piezoelectric lighter) with the ability to produce charge at any type of tension – compression or stretching.

Along with dumping effect they will produce a lot of electricity when riding (in any direction), which can be gathered and collected lets say in accumulator.

And if a car is using an electrical power source engine, these feature will let the generators to be charged continuously during the ride and make electrical powered vehicles even much more economical.

Static piezoelectric truss farm structures with gravity support reaction

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 ?
