Superfluids such as liquid helium cooled below the lambda point exhibit the Rollin effect where a thin film climbs the walls of the vessel. This still and video from the 1950s shows the effect, where drips of liquid helium form below a cup of liquid helium.
If the superfluid climbs the walls of a vessel, then logically it should climb the walls of any structure placed in a pool of superfluid. So if I placed a tower with a shape similar to this (rough) diagram:
Then the superfluid (shown in orange) should flow up the walls of the tower and collect under the end bowl section of the tower, and form drops of helium that would return to the main reservoir.
However if this happened then these drops could be used as an energy source, e.g. to drive a super-helium-powered water wheel.
My questions are: (1) would drops form on the bent tower? and (2a) if so, where is the energy coming from? (2b) if not, what is reason why it would not occur?
