[Engineer775 is always coming up with something cool and useful. This device he built from scratch and scrap materials and can be used to take advantage of the thermo-siphoning process... whatever that is. :) He mentions a previous video where he showed how to bend copper tubing with ice, which may be useful as well. As Engineer775 points out, this project is perfect for a rainy day!]
