Underwater turbines run into opposition

Source: Detroit News

In theory, it's a simple concept: Harness Michigan's wind and water resources to generate electricity to aid in the movement away from fossil fuels. In practice, however, it has become maddeningly complex for some trying to make it happen.

Projects designed to place towering wind turbines out in the waters of the Great Lakes where they would be most efficient have met with strong opposition from the public. That opposition is often based on concerns over impacts on fish habitats, recreation activities and views.

Underwater turbines, which capture the momentum of water currents in oceans, lakes and rivers, are starting to get the same kind of scrutiny. But so far, only wind power seems to be garnering support.

While Michigan has at least 23 wind farms planned or in operation, to date no offshore wind projects have been approved in the United States. So to help move those projects from the drawing board to reality, several Great Lakes states and 10 federal agencies have entered into a partnership to expedite testing and permitting process.

We even still have the dam and river running underneath the building. I've often thought it's silly to not use all that power being generated by the river.

3. There is that little problem of water turbines chopping up fish into bite size pieces.

Kinda hard on the water life and the life that depends on fish to survive.

5. I'm sure they could find a way to divert the fish to the branch of the river that run alongside

But, the building is owned by a management company and lots of the apartments are subsidized so it probably won't happen.

I can imagine them becoming a practical problem with underwater turbines. I say full steam ahead with wind farms though, recreational boaters and property owning nimby types need to make the decision between having electricity or nice view. fuck 'em.
