How does that work?

Rivers or canals have currents – both night and day, summer or winter – the river flows! It is from this current that we produce electricity. This is called kinetic energy or motion energy. The technology is similar to that of wind turbines but for a river. This is why we have installed small hydroelectric power plants with a patented anchoring technology in a nearby river or canal –

completely without a dam, without significant construction and without disturbing the natural or animal life in the river.Our mobile hydroelectric power plants are completely self-sufficient and independent of conventional energy sources. At the same time, they can provide helpful information like the water temperature, precipitation, water level and flow rate – all of which are important parameters to predict severe floods.

Application

Are you interested in using sustainable energy to make a contribution to the promotion of global energy supply, to be more independent and still to purchase your electricity more favorably than with a traditional supplier?
