The mineral is halite, whose main chemical component is Sodium Chloride (NaCl). Halite is an evaporite mineral-i.e. it forms as a result of evaporating water leaving behind â¦ dissolved chemicals as mineral deposits.
Passive Solar Energy Definition. Passive solar energy is the heating space that utilizes the design of the house or building so as trap solar heat when necessary. This means that the passive solar ensures that the house is not too cold during winter and not too hot in the summer.
In active solar energy special solar heating equipment is used to convert solar energy to heat energy whereas in passive solar energy the mechanical equipment is not present. Active solar include the use of mechanical equipment like photovoltaic cells, solar thermal collectors or pumps and fans to trap the solar energy.Passive solar technologies convert solar energy to heat energy without use of active mechanical systems.ctive solar include the use of mechanical equipment like photovoltaic cells, solar thermal collectors or pumps and fans to trap the solar energy.
