Tidal power is one of the only entirely predictable renewable power resources, and so it represents a very attractive source of large scale clean power. Existing tidal power generators require deep water to function properly, but the Pulse Stream 100 project could change all that. The Pulse Stream 100 uses underwater wings called hydrofoils to capture the power of the tides, and can therefore be used in much shallower water than traditional tidal power systems.
Inventor Marc Paish took his inspiration from nature, and began developing his design by examining the propulsion system used by marine animals: “A generating system is essentially a propulsion system turned on its head. The hydrofoils in the Pulse Stream 100 oscillate like a whale’s tail to generate power.” Tidal flows in UK waters are amongst the best in the world in terms of scale and location.With a strong marine and energy engineering base, the UK is well placed to lead the world in the development of tidal power. As the Pulse Stream 100 can be used in locations where other tidal power generators could not be considered, the potential for unlocking hitherto inaccessible clean energy is huge.
