Review on ๐ฌ๏ธ Solar Powered Glass Windmill Radiometer with 4 Blades - Light Mill for Study, Teaching, or Home Office Use by Michael Jennings
Cool and fun product for generators and portable power supplies
This is a very cool solar powered (thermal) device. Although the silver side of the petals has faded somewhat, the device spins freely in the sun even behind a slightly darkened office window. Cool retrospective science demonstrator that never gets old.
- This is amazing
