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.
The amount of heat energy received at any location on the globe is a direct effect of Sun angle on climate, as the angle at which sunlight strikes Earth varies by location, time of day, and season due to Earth's orbit around the Sun and Earth's rotation around its tilted axis.
We are like tenant farmers chopping down the fence around our house for fuel when we should be using Nature's inexhaustible sources of energy — sun, wind and tide. ... I'd put my money on the sun and solar energy. What a source of power! I hope we don't have to wait until oil and coal run out before we tackle that. ”
The heat index and humidex measure the effect of humidity on the perception of temperatures above +27 °C (81 °F). In humid conditions, the air feels much hotter, because less perspiration evaporates from the skin. The wind chill factor measures the effect of wind speed on cooling of the human body below 10 °C (50 °F). As airflow increases ...
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).
Tents can be defined by the number of season that they can be used. There are two-season, three-season and four-season tents. Two-season tents are ideal for warm/hot temperatures but do not cope well with rainy and windy conditions. Three-season tents can handle most weather conditions including rain and wind but will struggle in heavy snow.
The first product made with Gore-Tex fabric debuted in 1976 and was a streamlined, two-person tent called The Light Dimension. [2] The tent was created by Nicolai and William H. Edwards and was marketed by Ron Zimmerman. In 1975, Gore salesman Joe Tanner introduced Early Winters to the fabric product, which at that time was still without a name.
