I thought I had covered the Falkirk Wheel before, but I don't see it now. Its a fascinating and beautiful piece of engineering. Isn't even as energy intensive as you might think, given the balance between the two (extremely large) tubs of water. I hadn't seen this video of it in operation before:

Yet another design is shown on this French page. You can see some drawings/pictures part way down the page.

Klaus reports that wet and cold are keeping him from outdoor boat welding, but he is working on some plastic work for tankage.
