The more noise – the more energy

September 07, 2012

It may ”sound“ unbelievable but Practical Action, the organisation already mentioned in this blog, has developed a special stove which turns noise into electricity. This innovation has been invented with Paul Riley from the University of Nottingham as well as a consortium of UK universities

The ”Score-Stove“ has the potential to provide electricity to the world’s poorest people and give them access to light, heat, education and healthcare – in most cases for the first time of their lives. Originated from the desire to reduce deaths resulting from breathing in smoke caused by cooking on open fires in the home, university teams have created more efficient and less smoky cookstoves which require less wood. The technology was optimised during this development process: The ”Score-Stove“ is about 60 cm square and around 70 cm high. The heat causes dozens of thin metal sheets with tiny holes to vibrate within a special pipe attached to it. These powerful sound waves travel into a speaker and cause it to flap at up to 70 times a second. A connected alternator then turns these fast moves to electricity.

The next step is to adapt the current lab version taking into account specific local conditions as well as the range of tasks the unit will be required to perform. Slight design modifications are needed so that the stove is adapted to local conditions. Once this has been undertaken, however, it will be possible to produce the stoves affordably and locally.
