in spite of the declares of “free energy” on the title of the video below, this is not yet one more goofy perpetual movement story. We right here at Hackaday completely support the legislations of thermodynamics, as well as we believe you ought to too. however you have to admit that a pump that works without any type of obvious energy inputs looks type of shady at very first glance.

The apparatus in concern is a ram pump, a innovation dating back all the method to the 18th century. The version that [Junkyard – origin of Creativity] developed utilizes typically offered materials like PVC pipes as well as fittings. about the only things on the BOM that may be difficult to scratch up are the brass inspect valves, which ought to most likely be flap valves rather than the simpler to discover spring valves. as well as the only customized part is an adapter to thread the plastic soda bottle that’s utilized as an air chamber to the PVC, which a 3D printer might take care of if you select not to hack a bottle cap like [Junkyard] did. The video below shows the outstanding lift accomplished just by tapping the kinetic energy of the incoming flow.

There, the second legislation of Thermodynamics stays inviolate. however if you still believe you can get something for nothing, inspect out our roundup of perpetual movement as well as Overunity quackery.
