This is very cool. Harnessing the ocean’s energy has been a goal of many for years. Cape Cod is surrounded by some of the strongest currents in the world. The Cape Cod Canal is actually a “hydraulic” current, which means that water is always moving at some point along the canal. It is easy to envision a submerged turbine whose blades are turned by the moving current, generating energy every hour of every day, rain or shine, wind or calm.
Here is a house design that incorporates a turbine to transform the kinetic energy of waves into electrical energy for the house. The exterior cement shell of the house is bound to take a beating, but the wave energy should be substantial. Frankly, harnessing a steady current would probably produce more predictable energy every day. I would be surprised if using the energy of the ocean isn’t much more common in the years to come.
And Cape Cod is the perfect place to harness the endless energy of the ocean! Take a look and see what you think:
