I saw the first photo a couple of days ago and thought this was a neat way to move water. Water is very heavy, manually moving it over distance can be difficult.
I've thought about something similar using wooden cable spools before but seeing these variations gives me ideas. Cables spools are common from 2ft to 6ft, keeping a couple stashed in the barn might be a good idea if you have the room.
Anyway, I found a webstie promoting these water rollers in poor areas of Africa where people have to carry water long distances...
