Ram Pum in France

**Explanations of how it works: put the subtitles**
Installation of a ram pump made of steel, copper and brass. This system without electricity and without carbon emissions makes it possible to raise the water of a river. A height of 2 meters in this installation makes it possible to raise the water to 30 meters in height. You can see with the thermal imaging camera the space occupied by the compressed air: the remaining area has a higher temperature than the pump body.
