Water wheels, pumps and recirculatin mills

Recirculation Mills Normal mills need a continous water flow to power their water wheel. The basic idea of the recirculation mill is the usage of a a closed water system. Such machines sometimes are called dry water mills. Since the water does not come from external sources, it was called aqua morta "dead water". The intended advantage of this mill is clear. There is no need for a permanent water flow, .
