This is a concept of a water pump that runs with the energy from running water i.e. hydro-kinetic energy. It consists of a piston pump that is compressed by a lever driven by the pedal wheel. The pedal wheel is pushed by the running water - greater the area of the pedal, the greater the compression force. Similarly, rivers with high velocity can pump water to greater heights. 

I conceptualized this pump during my third year of civil engineering but later I was more invested in other projects, so I could not give continuity to this project. The model was designed and animated in Solid Works. The video and all the preliminary calculations are attached to the page.
