This is an industrial snow removal device which uses concentrated solar energy to heat snow or ice such that it melts into water. This is achieved by focusing sunlight through a Fresnel lens. Depending on the sunlight, the resulting water can then be evaporated by continued use of the device.
On days with clear sunlight, the framed and covered Fresnel lens (minimum dimensions: 2 feet by 2 feet) is positioned just above outdoor snow, firmly in place using a lattice. It is then uncovered and carefully adjusted as needed so that its focal point is on the snow's surface. Dark sand is then placed on the snow's surface to absorb the heat of the sun's rays, otherwise the white colour of the snow will reflect the sun's rays. As the sand's temperature rises from the concentrated solar beam, the snow melts into water. Carefully refocusing the Fresnel lens on the resulting water can then evaporate it, thereby eliminating the snow entirely. The lens must be covered before it is moved to another area. Caution: As with all magnifying lenses, there is a danger of property damage or serious injury if the solar beam is aimed at any living beings in the vicinity. For this reason, the lens must always remain covered unless it is in use.
