Solar Powered Metal Windmill Model with Black Panel and Gold Base

This solar-powered windmill model combines a Black solar panel, metal rotating blades, and stable Gold base for desktop display and science demonstrations. When placed in direct sunlight or under a sufficiently strong indoor light, the panel converts light energy into electricity and turns the windmill automatically; the blades stop when there is no usable light. No batteries or wiring are required. Durable metal construction is described for repeated classroom or home use, while the compact footprint fits desks, shelves, or windowsills. The model provides children or adults with a visible demonstration of solar-energy conversion and can be used for science projects, educational displays, renewable-energy discussions, or as a decorative mechanical ornament.
