In Mongolia cheese and meat are still traditionally dried using the top of the ger (tent) as a solar dryer. [3] In these systems the solar drying is assisted by the movement of the air (wind) that removes the more saturated air away from the items being dried. [2] More recently, complex drying racks [4] and solar tents [5] were constructed as ...
Seasonal thermal energy storage (STES), also known as inter-seasonal thermal energy storage, [1] is the storage of heat or cold for periods of up to several months. The thermal energy can be collected whenever it is available and be used whenever needed, such as in the opposing season.
[59] [60] In Canada, single building thermal storage also stores renewable solar and wind power as heat, for later use as space or water heating for the building in which it's installed. It differs from the system in Finland by being compact, using low pressure pumped fluids, and can only heat one building rather than several.
A lantern is a source of lighting, often portable. It typically features a protective enclosure for the light source – historically usually a candle, a wick in oil, or a thermoluminescent mesh, and often a battery-powered light in modern times – to make it easier to carry and hang up, and make it more reliable outdoors or in drafty interiors.
Therefore, the sunbeam hitting the ground at a 30° angle spreads the same amount of light over twice as much area (if we imagine the Sun shining from the south at noon, the north–south width doubles; the east–west width does not). Consequently, the amount of light falling on each square mile is only half as much. Figure 3
A dunkelflaute of three days in Germany 2023 (wind in light blue and solar in yellow) In the renewable energy sector, a dunkelflaute ( German: [ˈdʊŋkəlˌflaʊtə] ⓘ , lit. ' dark doldrums ' or ' dark wind lull ' , plural dunkelflauten ) [ 1 ] is a period of time in which little or no energy can be generated with wind and solar power ...
The tents also covered with hides. A Yaranga (Chukchi: Яраӈы, Yarangy) is a tent-like traditional mobile home of some nomadic Northern indigenous peoples of Russia, such as Chukchi and Siberian Yupik. A Yaranga is a cone-shaped or rounded reindeer-hide tent. [1] It is built of a light wooden frame covered with reindeer skins or canvas sewn ...
The albedo of several types of roofs (lower values means higher temperatures). Reflective surfaces, or ground-based albedo modification (GBAM), is a solar radiation management method of enhancing Earth's albedo (the ability to reflect the visible, infrared, and ultraviolet wavelengths of the Sun, reducing heat transfer to the surface).
