I need help please. I would like to make a board which has pinwheels turning on one side, and a motor turning that motion into electricity to light a bulb or a digital display. I am not trained in “Science” speak - please respond in English. I’ve been told I need a “Permanent Magnetic Brushed DS Motor” but I don’t know what that is or how to connect it to the pinwheels and connect the motor to the light or display. I have a limited budget but all summer to turn this idea into a tool to show children how windmills create electricity, a controversially subject here in Oregon. Any and all suggestions welcome and credit will be given to those who help me with this project. I live in Portland, OR and perhaps you can direct to a local shop which would have the parts of this machine. Perhaps I am asking something too difficult and/or too expensive. I rejected the idea of using changes in earth temperature to generate power, or something to dip into the water of our many creeks and rivers. Did I give up too easily? All advise is welcome. Thank you. Mary F. Byrkit, Portland, OR, USA
The principle is actually really simple: spin a DC motor and you will get current which you can use to power other devices.

The motor on this device is small and intended to generate wind rather than use it.
It’s something like this: robotshop.com/en/solarbotics … tor-2.html
If you can find pinwheel you can replace it and rotate it to see that you can use the red and black terminals to generate electricity.
If the water is moving fast, you can add gearing to the motor to have it generate more electricity over the same amount of time.
