These are IDEAS only. Not Step by Step building plans.
Use your ideas to make the Lego generator spin. Here's how a Lego bicycle might be connected to a generator to make it spin.
You can't make exactly this. But with the generator on the base, you can use some gears in a way similar to this photo and then have something move it in a circular direction like this old machine below.
This isn't a solution that will work for the design challenge, but it will generate electricity if you're stuck!
The blades on this will not spin from wind because they have holes in them and they don't have the right shape, they're Lego. However, the idea works. You can build something similar to this photo and then push the wind mill with your hands. The base of this design does not click to a green base. You'll have to modify that.
You can build something similar to this photo and attach some Lego to make the shaft spin by something such as human or animal power, or maybe you have another way to make it rotate. The base of this design does not click to a green base. You'll have to modify that.
