The build
Step 01
Make blades
Cut and angle blades on a hub.
Step 02
Mount the generator
Fix the hub to the motor shaft.
Step 03
Wire output
Connect to an LED or meter.
Step 04
Face the fan
Aim a fan and read the output.
Working Principle
Wind spins the angled blades, turning the motor as a generator that induces a voltage — mechanical energy becoming electrical.
The science behind it
A closer look
Blade count and pitch set how much wind energy is captured; the same induction as power-station generators applies.

Variables to test
- 1 Test 2 vs 3 vs 4 blades for output.
- 2 Change blade angle — find the best pitch.
