Water Pumping Demo

[SSN]

Hello,

I was at a folk festival this summer and I saw a solar demonstration taking place. They had a solar panel connected to what looked like a copper tube. The copper tube was standing upright in a bucket of water. When the sun was out the contraption would act as a fountain. Does anybody know how or why this works? I want to do it on a smaller scale for an inside waterpump/fountain.

Maybe Thermal

Maybe I'm wrong but it sounds like they were doing by thermal means. Think of the same way a coffee pot works.

That is very odd in deed. Are you certain there wasn't an (in line) water pump they were showing off that was in side of the tube or connected to it at the bottom?

Definitely need more information. Based on what you have, there are many, many ways to achieve this, some simple, some complicated. I believe it may have worked by capillary action. It depends on how thin the tube was.
