In Boeing suggested to extract an electricity from noise of planes

The employee of Boeing aviaconcern found a way to benefit by a roar of jet engines of planes. Noise can be transformed to an electricity, it is told in the new patent. About the invention reports Gizmodo.

«Acoustic energy from flying-up and sitting-down planes dissipates in air and represents the resource lost for the person», – the engineer Chin Tokh (Chin Toh) writes.

The inventor suggests to reconstruct runways, having established on their perimeter of the device on collecting acoustic waves. They will collect and focus sounds (that is vibrations) from engines. Then this oscillatory energy is converted in the stream of air actuating the turbine. The electricity generated by such turbines, will gather several substations.

Thus in the patent it is reported nothing about system efficiency that removes terms of its possible installation at the airports on the long-term future. Scientists from Massachusetts Institute of Technology note that the weakest place of similar projects is low efficiency of devices on collecting acoustic energy.

Noise from jet engines (its level of loudness reaches 140 decibels) remains an important unresolved problem of the airports. So, the Amsterdam air harbor Skhipkhol ordered the large-scale landscape architecture, capable to muffle the noise, however the empty territories necessary for implementation of this decision, is not at each airport.
