Aquädukt
Privatbesitz Aachen/De
A double cone runs on rails above an aqueduct. The water level in the aqueduct rises and falls by means of a suction pipe whereby the rails are tilted causing the double cone to roll to and fro. The water outflowing in intervals supplies a WaterTumbleDisk (WasserTaumelScheibe, a disk made to tumble by waterpower).
