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 ...
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.
[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.
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.
In addition to the density of incident light, the dissipation of light in the atmosphere is greater when it falls at a shallow angle. Figure 2 One sunbeam one mile wide shines on the ground at a 90° angle, and another at a 30° angle. The one at a shallower angle covers twice as much area with the same amount of light energy.
101. Work a Jigsaw Puzzle. Depending on the size of the puzzle, you might want to set aside a few hours at a time to work on the puzzle. It's not likely you'll finish in one session.
Sky lanterns have been made for centuries in cultures around the world, to be launched for play or as part of long-established festivities. The name sky lantern is a translation of the Chinese name but they have also been referred to as sky candles or fire balloons.
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).
