A large solar furnace can produce enough electricity to power a small community. These furnaces involve concave mirrors as they converge the parallel sun rays at a point. Furnace igniters work by creating a spark to cause ignition, or by producing an extremely hot surface that ignites the gas as it passes. The ancient Greek / Latin term heliocaminus literally means "solar furnace" and refers to a glass-enclosed sunroom intentionally designed to become hotter than the outside air temperature.[1]. It is 48 metres (157 ft) high and 54 metres (177 ft) wide, and includes 63 heliostats. The mirrors are arranged around a central collector tower, and reflect sunlight into a concentrated ray of light that shines on a focal point on the tower.In previous designs of solar power towers, the concentrated sunlight heated a container of water, which produced steam that powered a turbine. The reflective surface of this concentrator can be from one to one hundred square meters. Some solar energy technologies include photovoltaic cells and panels, concentrated solar energy, and solar architecture.There are different ways of capturing solar radiation and converting it into usable energy. Some years later, on the model of the Mont-Louis furnace and using the results obtained there, a solar furnace of almost industrial size was built at Odeillo. Two solar heating methods will work to heat your home - passive solar heating and active solar heating. The process involves: Removing the metal frame, glass cover and junction box. The process involves molten salt being pumped into the furnace to raise its temperature. When the sun rises, it begins to warm objects and material on Earth. This process of generating electricity directly from solar radiation is called the photovoltaic effect, or photovoltaics. Generated electricity from the generator is distributed to an electrical transformer where the voltage is increased. Modular cooling towers are used to cool the steam back to condensate.
