The Sonea is a concept gadget that converts noise to energy to be used to power things such as lights, mobile phone chargers and even TV's.
The device needs to be installed in a very noisy environment to be useful, so keeping it at home might not be the best option and instead, stick it in a local construction yard.
According to it's designers it is capable of producing 30 watts of power for each decibel of sound produced. If installed on a runway the noise from a plan can produce 240KW of power.
I'm not sure about this myself as it all seems a bit too theoretical and maybe slightly exaggerated as I would have expected a whole wall of these would be needed to produce any decent amount of power.
