This is typical system of turbine to use water harvesting. This made bymany fans to spin and we can use plastic bottle for these fans.

This is not a normal turbine system, and I think that this system will beeasier than normal system of turbine. This still need a generator, butthis will helpful for thinking about other way to make and use turbine.

This is the way to use magnet for turbine.

We may not produce a lot of energy for electricity to use rain waterharvesting, so this kind of use of small LED light-bulb can be veryuseful.
