Solar forge Guide, Meaning , Facts, Information and Description
A solar forge is a device that uses the power of the sun to melt materials, such as asphalt. A four foot wide fresnel lens is positioned as a lid of a hollow standing cylinder. The lens focuses the sun's radiation to a point inside the cylinder, where the material to be melted is placed. The effect is the same as a magnifying glass used to burn a dry leaf, except that the heat achieved is much greater. The focused light is similar to the concentrated light of a laser, though not as intense.Solar forges work best in desert areas where there is plenty of sunlight. They are dangerous to approach because of the great heat and light generated. A safe way to handle the danger is to uncover the lens in the morning before the sun rises before leaving, and return to cover it after the sun sets. Solar forges are easy to build, because they consist of only two parts. Other optional parts are : a cover, a pollution-control device (for the smoke), a vent, a temperature gauge, protective fire-proof clothing, and gas masks. Solar forges have the benefit of cheap construction and no fuel cost, unlike other forges. However, they cannot achieve the higher temperatures that other forges can. They are good for melting materials with low melting points.
Theoretical future uses
Solar forges can achieve higher temperatures on moons and planets with no atmosphere to block solar radiation. There, they can melt denser materials with higher melting points. If the solar forge is not hot enough, multiple lenses in a row can be used. They have also been considered for use on the space stations and space mining colonies of the future. The super hot beam produced by the solar forge could theoretically melt through rock, making mining on other planets and moons easier, and with no fuel cost nor machine work. The solar forge might melt moon rocks, creating smoke that contains mineral gas, carbon, trapped air (nitrogen and oxygen), and water (hydrogen and oxygen). The smoke could be filtered to seperate air and water to be used by colonists for drinking, farming, bathing, washing clothes and dishes, and other uses. By releasing water from a dry planet, solar forges could make colonization possible. The earth's original carbon dioxide atmosphere was created by the smoke of molten rock ejected by primieval volcanoes.
