Water Pump

There are many small water pump here. Therefore i had small DC motors used ion DVD player sold for US$2, the i make it.

The first turbine had straight blades and did not work well. I redesigned the second turbine by looking at various designs here and inspiring them.

It did not reach the height of 80 cm. The flow has decreased and up to 60 cm should work.

I sealed it with hot glue. Now I'm going to test the durability. under continuous use.

I made a simple video to ilustrate it. https://youtu.be/4OlW5PFYYWE
