The London Telegraph
revealed a plan to generate electricity by harnessing the power of fish migrating upstream:
The project, codenamed 'Finetics', builds on Japanese technology that captures energy from people walking over pressure sensitive mats at train stations.
Research found that a typical salmon, which zips through waters at a top speed of 12 metres (40ft) per second, can over a 100m (330ft) stretch generate enough electricity to make 18 cups of tea, while the more shy rudd will only trigger enough power for three cups.
Multiplied many times over by the millions of fish that thrive in rivers and waters across England and Wales, the Environment Agency scientists estimate the amount of electricity generated could power around 30,000 homes a year.
The article quoted Gavin Roach, "a world-leading specialist in green technologies based at the Université de Poisson d'Avril in Paris," as saying, "The Environment Agency team has made a very exciting breakthrough. Finetics clearly has the potential to create significant amounts of power by simply harnessing the power of nature."
