What is it?

Spyragen consists of an Archimedes screw placed inside a specially made trough along the cascade.

The generator works in the opposite direction to that of a normal pump harnessing the potential energy of the waterfall where the machine is installed. The water moves the auger that is connected to a gearbox, which in turn drives a generator; the Generator produces electric current using the energy from the cascades.

The ongoing commitment to innovation led our research to identify new mechanical and electronic solutions, which maximise the energy efficiency.

The technology, based on dedicated electronics and a sophisticated reworking of the contours of a hydraulic auger, allowed the construction of a hydroelectric generator with an efficiency that is difficult to match.
