They can be used, for example, as a source of natural lighting or as concentration systems in thermal and photovoltaic applications. This manuscript describes a new simple polar heliostatic system suitable for small applications whose movement is controlled by a unique engine, reflecting sunbeams parallel to the Earth¿s axis with pointing average errors around thousandths of a radian.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786202063067\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9786202063067","offer_id":39460266639453,"sku":"9786202063067","price":28.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/5d8be4e2-a92c-436f-bba6-8f5218a29f0a.jpg?v=1757744154","url":"https:\/\/shop.autorenwelt.de\/products\/polar-heliostat-for-urban-applications-von-manuel-torres-roldan-rafael-lopez-luque-marta-varo-martinez","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
