The Globe and Mail has a report on some tentative first steps towards building large scale tidal power projects in Canada's Bay of Fundy - Monster turbines gear up to harness Fundy tidal power.
A full-scale tidal energy project, if viable, would involve hundreds of turbines and could produce about 100 megawatts from the bay's huge tides. That would be 10 per cent of the province's energy needs, but such a system is years away.
The demonstration phase of the project, involving three turbines, is expected to cost $60-million to $70-million. Each of the three companies involved - which will co-operate on environmental monitoring and onshore development - intends to test a different type of turbine. ...
The model chosen by Nova Scotia Power is similar. About six storeys high, with a turbine 10 metres across, it will use gravity to stay still underwater. This design is expected to be in place first, with the turbine going into the water late next month. It will not initially feed power into the grid.
