@mrblissett It's a front wheel from a second hand bicycle with a "hub dynamo". Should be a light pole on a campsite where there is no electricity.

But currently the main challenge is to make the blades bigger. Until now it did not rotate a bit, without turning the wheel by hand 😂

@dbread
That's a way better start than a clothes-washer motor - you've got a lightweight wheel already mounted to the generator
