This week’s segment looks at a Canadian company that is trying to use ocean tides to create renewable energy. 

Transcript: 

A Canadian company is looking to harness the tidal pull of the ocean for energy.

This is the Iowa Environmental Focus.

Cape Sharp Tidal is a company located in Nova Scotia by Canada’s Bay of Fundy. The Bay of Fundy is known to have some of the highest tides in the world. The differences in water levels between high and low tide are sometimes as large as 50 feet.

Christian Richard, the company director, was inspired by the way wind turbines collect energy by using air currents to turn the turbine blades. Using the tides for energy would work in much the same way, with the sensors being placed underwater and using the changes in the pull of the tide to generate energy.

The technology is still in the early stages of testing. The development team must work on everything from the design, to the efficiency, to proving that the invention won’t harm marine life.
