Canada harnesses power of tides

The one thing that every schoolchild learns about the Bay of Fundy is that it has the highest tides in the world.

The North Atlantic waters are funnelled up this deep inlet between the Canadian provinces of New Brunswick and Nova Scotia, swirling through the narrowest parts of the bay with impressive speed and power.
So when in the 1980s the Canadian government wanted to explore the feasibility of tidal power, this was a natural site for an experimental station.

The site chosen at Annapolis Royal had already been closed off by a causeway, built to control tidal flow further up the Annapolis River.
