Solar dryers are special structures that enhance the drying power of the sun and protect the agricultural product from dust, dirt, and insects. Table below shows a block diagram of an active solar drying system, consisting of solar air collectors, a drying unit or chamber, and an air handling unit. An active solar drying system can accommodate the use of a backup heat source when there in not enough solar heat available. (more…)

Active solar hot water systems water are usable with air, liquid, vapor or liquid collector fluid or gas to liquid process. Hot water production with an air-heating collector’s distribution for heating is usually performed in the large space heating panel systems. The losses in the process of heat transfer are high. Air systems work not as well as units of the liquid to heat the water. Air systems are generally only capable of hot water 70 to 95F. (more…)

Several passive heating systems, if provided with proper ventilation, can ensure to provide cooling. Passive heating and cooling for houses can be done in several ways, one of which is called geothermal energy. Passing the water through pipelines via ground can achieve and distribute the heating and cooling all over the house. (more…)

Geothermal energy is energy created by the heat of the Earth. Under the Earth’s crust lies a layer of thick, hot rock with occasional pockets of water. This water sometimes seeps up to the surface in the form of hot springs. Even where the water does not travel naturally to the Earth’s surface, it is sometimes possible to reach it by drilling. This hot water can be used as a virtually free source of renewable energy, either directly as hot water, steam, or heat or as a means of generating power. Geothermal energy as renewable energy is nonpolluting, inexpensive, and in most cases the sources is renewable. (more…)
