In the summer of2025 Alex Fletcher and his son Yanou visited the Museum of Technology in Ottawa. They encountered the Tidal Current generator that was installed at Race Rocks Ecological Reserve  in 2006.

The Clean Current technology is an example of a ducted horizontal axis turbine designed for ocean tides and salt water. It is bi-directional (designed for the ebb and flood tides) and highly efficient. It is very simple in design with one moving part, the rotor assembly that contains the blades. There is no driveshaft or gearbox. Clean Current’s direct drive variable speed permanent magnet generator incorporates features that allow the generator to be configured to produce either alternating or direct current.
