This made me realize that there are no lifeforms getting energy by mechanical means (harness wind, waves, tides). That seems like an oversight on evolution's part!

There are, however, plants and animals that harness mechanical energy as a survival strategy, which might amount to the same thing. For example when dandelion seeds get spread in the wind, or fish swimming along ocean currents.
I think a good rule of thumb, given the extreme diversity of the biological world, is that if a specific biological mechanism hasn't evolved in 4 billion years of evolution there's probably a good reason for it.

Biological evolution does a pretty poor job of mechanical adaptations in general. For example in the entire history of life on Earth there's no instance of a true wheel being developed.
I'd say evolution is really good at chemical engineering, decent at aerospace engineering, okay-isn at electrical/computer engineering, and incompetent at mechanical engineering.

If you believe that humans are too just products of evolution, then I'd say evolution gets credit for aerospace engineering too.
