Review on π¬οΈ Solar Powered Glass Windmill Radiometer with 4 Blades - Light Mill for Study, Teaching, or Home Office Use by Muhammad Balding
Black dust is best for solar and wind power
Unfortunately, as another reviewer mentioned, I'm also missing the black paint/color, resulting in black dust on the inside of the glass. There are 2 photos.
Pros
- Free for educational purposes
Cons
- Some bugs
