Is it possible to obtain water with a suction pump without the use of electricity or fuel? what physics tells us on this subject, there are currently many videos talking about Free Energy Water Pumps that can apparently suck water from a well, an irrigation canal, a lake or a river and suck water to then pump it to fields that are at higher levels and 20 meters away, are these videos FAKE or is it a real renewable energy solution? In this video, a scale model of this pump is made and tests are carried out rigorously to determine if a suction pump with a metal tank and some plastic tubes is possible without the use of external energy.
A technological development with the aforementioned characteristics would be of great help for agricultural or livestock applications, however, it is necessary to analyze in depth what the benefits of these so-called "suction pumps" or "pumps without energy" are.
