Universal Hydropower

A closed-loop hydropower generator

Currrent large-scale hydropower units take up lots of space, disturb local marine life, cost a lot of money, and are hard to use in arid or desert landscapes. My experiment aims to create a hydropwer unit that takes up less space, doesn't disturb marine life, and can be used effeciently in arid places.


1 - Filling out and submission of the project proposal for teachers to review

2 - Background research and early stages of the presentation

3 - Designing and building of the actual experiment

4 - Testing and improvements of the experiment

5 - Experimenting and recording power output of experiments

  • 1 - Fill lower tank with water
  • 2 - Open outflow valve
  • 3 - Push water out of lower tank and record voltage output
  • 4 - Close outflow valve and wait for the top tank to fill
  • 5 - Open inflow valve
  • 6 - Wait for lower tank to fill and record voltage output
  • 7 - Repeat valve/water sequence as much as needed

6 - Finishing the rest of the presentation and theorizing about possible improvements to the experiment and the machine.


When the experiment was performed, there was voltage produced by the water flowing out of the lower container but no voltage produced by the water when it was flowing out of the upper container. This may have been due to the head pressure in the tubing, which could have slowed the water enough that it was not spinning the generators. This means that there is only half of the estimated output, and that the experiment requires modification.


My hypothesis was incorrect, and the experiment did not function as expected. The experiment did not produce any significant amount of electricity. Without more testing and improvements being made to the machine, it would not function as a viable long-term energy source in any environment or situation. 


I acknowledge that Michael McClocklin, my father and a registered Master electrician, helped me with acquiring the materials for the construction, and with planning and execution of the experiment.
