Engineer David Mummery's Swimmer Turbine could power coastal communities with small-scale tidal energy

Engineer David Mummery developed the Swimmer Turbine, a 50kW small-scale tidal generator anchored to the sea floor, which can power about 30 homes. Mummery designed the device to be assembled by local fishermen from harbor components, likening it to an Ikea furniture kit. The turbine is part of a broader Scottish-led tidal energy sector that includes the world's first tidal stream array and largest tidal array.
