Tidal Flyer Ltd.
Tidal Flyer is a Tidal Energy Converter (TEC) using tidal streams to drive a loop of vertical underwater hydrofoils, supported on cables top and bottom, and spanning part way or fully across a channel. The Tidal Flyer concept belongs to the family of vertical axis turbines that extract energy from the tides in a similar manner to horizontal axis devices, except that the turbine is mounted vertically. The tidal stream causes the foils to transverse the flow thereby rounding 4 No. vertical axes to complete one full rotation; power is generated on both upstream and downstream lines with 2 No. Power Take-Off units per system. The unique selling point for the concept is the very large swept area which is expandable and scalable which in turn provides a high efficiency for a tidal device of approximately 44%.
