Harvesting energy from urban noise,
natural sound sources and factory machine tools.
Unlike existing renewable energy sources: solar, hydro, wave, wind,
geothermal, biomass, all of which require relatively large and free
space and cannot be located in a densely populated city. On the contrary,
the energy obtained from urban noise is inferior in power the above,
although it can be used by citizens, especially those living in
metropolitan areas. However, this does not exclude the possibility that
this device can be placed in naturally noisy places (eg near a waterfall,
etc.), as well as near factory machines that produce a lot of noise.
Stage one
To determine the shape and frequency of a bottle-shaped objects, the number and position of these objects and the type and power of the electric motor.
Stage two
Replace speakers with devices that pick up environmental sound, shape it at a specific frequency, and amplify that sound.
