Soundscraper – energy from noise.

No, I’m not drunk. A soundscraper is a serious thing in the race towards clean energy.

As found on Inhabitat:

An entry in the 2013 eVolo Skyscraper Competition, the Soundscrapers would be constructed near major motorways and railroad junctions, prime locations for capturing ambient vibrations. A sound-sucking material would cover the exterior of the tower with a double-skin layer, held away from the façade on a metallic frame.

For each Soundscraper, 84,000 electro-active lashes would cover the metal frame and pick up noise from cars, trains, pedestrians and passing planes. Each of the lashes is armed with sound sensors called Parametric Frequency Increased Generators. Once the noise is picked up, an energy harvester converts the vibrations to kinetic energy. Transducer cells then convert the energy to electricity, which is stored or distributed to the grid for regular electric use.

The team estimates that just one Soundscraper could produce 150 megawatts of energy in a densely populated city, which roughly converts to 10% of the lighting needs of Los Angeles. The clean energy would also help the city reduce carbon emissions and reliance upon fossil fuels. Several Soundscrapers could drastically offset the electrical needs of a metropoli

One thought on “Soundscraper – energy from noise.”

  1. Please, this is totally unrealistic.

    One car gives off at most 10 W of acoustic power. There are about 300000 cars traveling in a big city (20 km diameter) at peak hours.
    This is to say 0.000956 cars per square meter, or an acoustic power density of 0.00956 [W/m^2].
    Given that the city is much larger than the soundscraper, it can be assumed that the acoustic field is uniform and has about the same intensity as the field generated by an infinite plane of acoustic sources.
    Therefore the acoustic power density arriving at the soundscraper is also 0.00956 [W/m^2].
    But, every single point on the soundscraper surface can see only half the surrounding circle, hence the acoustic power density landing on every point is 0.00478 [W/m^2].
    If the soundscraper is a cylinder having 40 meters diameter and 200 meters height, its surface area is 25120 [m^2].
    Finally, the total acoustic power that can be harvested is only 25120*0.00478 = 120 [W].
    More like 150 W than 150 MW.

    Ah, designers.
