It doesn't seem that special to me. That might be because I don't understand Japanese language.... But, the pump design looks very similar to a "Roots blower." Also, what about the tolerances? The tolerances matter when you want it to be able to work efficiently. Another problem with the design in the video is that the output is pulsating. That isn't good for liquids, because liquids are hard to compress. The pulsating pressure would cause a lot of vibration and stress on the pipes.

ever hear of googletranslate this seems to be an air-powered water pump design. the air pressure may be produced by using water in confined spaces and gravity to move / pressurize the air. this idea is probably fatally flawed. but you never know. cheers
