The materials could be scrap pipe, and no machining or skills are needed to build it. The slow rotational speed can be stepped up to whatever is needed, just as with the old-time waterwheels. No fuel would be needed in many cases. There are NO restrictions on building or experimenting with the wheel. Polygon wonder wheel is made of individual containers.
Tubes connect opposite pairs.
I wasn't sure it would run. Speed is about one rpm, but torque is strong. Low-boiling liquid, such as freon or propane, fills one bottle of each pair. The opposite bottle is empty and void of air. As each pair shuttles its liquid mass back and forth, the whole thing turns and repeats the process endlessly.
