This exquisitely crafted, handmade glass windmill features a partial vacuum bulb housing four delicate rotating vanes. When placed under direct sunlight, artificial lamps, or infrared radiation, the dark and light sides of the vanes absorb energy differently, causing them to spin in silent, hypnotic motion. The stronger the light source, the faster it rotates. It serves as an exceptional educational tool for physics students, teachers, and science enthusiasts to visualize thermodynamics and solar energy principles in real-time. Designed primarily for adults and older children, this elegant, crystal-clear glass sculpture adds a sophisticated, intellectual touch to any office desk, living room shelf, or classroom. This conversation-starting device requires absolutely no batteries, plugs, or external power sources, making it a sustainable, mesmerizing testament to classic scientific discovery.\u003c\/p\u003e","brand":"DORAMI","offers":[{"title":"Default Title","offer_id":52031711969597,"sku":"Rudra-B07BGSMBX9","price":4069.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0991\/7602\/2333\/files\/padded_1774011119.jpg?v=1784891484","url":"https:\/\/rudraretails.com\/products\/dorami-large-transparent-solar-power-crookes-radiometer-4","provider":"Rudra Retails","version":"1.0","type":"link"}
