Future energy conversion towers make urban noise no longer redundant

The future concept tower called soundscraper is a device that can convert urban noise into clean energy. This conceptual device was designed by five designers: Julien Bourgeois, Olivier Colliez, Savinien de Pizzol, Cedric Dounval and Romain Grouselle.

The Soundscraper is entirely covered with 84,000 noise-sensitive cilia. Through these cilia, it can absorb urban noise pollution and convert it into kinetic energy.

The designers conceived to build this concept device near major highways and railway hubs in order to maximize noise absorption. These noise-sensitive cilia are sound-absorbing materials and cover a full two layers outside the tower.

Obviously, the key lies in these 84,000 electroplated active cilia. They can absorb and convert the noise from cars, trains, crowds, and planes flying over the air into kinetic energy. Each cilia has a built-in sound sensor called Parametric Frequency Increased Generators. Once absorbed, the built-in energy harvester will convert the sound vibration into kinetic energy. The transducer then converts the kinetic energy into electrical energy. Finally, these clean energy sources can be stored or distributed to various transmission networks.

According to designers' estimates, in a densely populated metropolis, such as Los Angeles, only one soundscraper can produce 150 megawatts of energy. In other words, a soundscraper can provide 10% of lighting power for Los Angeles. Such clean energy can also contribute to reducing carbon dioxide emissions in cities and reducing residents’ dependence on fossil fuels. Imagine that if you build several such energy conversion towers in major metropolises in the world, it will be possible for clean energy to completely cover urban electricity.
