Lars Egil Helseth (Department of Physics & Technology) – Electric production from raindrops

Lars Egil Helseth from the department of Physics and Technology explained how electricity can be produced directly from raindrops. By using an energy conversion unit in the form of a triboelectric or piezoelectric transducer, the mechanical energy of raindrops can be converted into electrical energy.

It is also an idea to use this technology together with solar cells: Improving today's solar cells using a transparent thin film of polymer covering the solar cell, you could use the same device to produce energy while it is raining.
