Solar distillation is the process in which solar heat is used to purify water from an impure water source by evaporation and condensation. When solar distillation is used to purify water from saline water, the process is also called solar desalination. Desalination converts saline water with high salt content, about 3.5% by weight in seawater and about 0.6% in brackish water, into fresh water suitable for drinking and other purposes. Use solar energy can be used for desalination, either as thermal energy through the use of solar thermal collectors or solar ponds, or as electricity. mainly through the use of photovoltaic cells.

Earth’s climate is a complex system of interacting natural components. These components include the atmosphere, the ocean, and the continental ice sheets. Living things on earth—or, the biosphere—also constitute an important component of the climate trends system.
Numerous factors influence Earth’s climate system, some of them natural. For example, the slow drift of continents that takes place over millions of years, a process known as plate tectonics, influences the composition of the atmosphere through its impact on volcanic activity and surface erosion.

As a result of high and rising costs of fossil fuels and fossil fuels affect global environment concern , and by the reduction of greenhouse effect gases from burning causes (Kyoto Protocol), the heat recovery gain importance growing. A heat exchanger absorbs a significant portion of the heat energy of the gases generated during combustion of solid fuel, liquid and gas in the smelting process, heating, roasting, and drying.

Since preindustrial times, ambient concentrations of the greenhouse gases have exhibited substantial increases, inter alia CO2 by 30% to about 360 parts per million (ppm), CH 4 by 145% to more than 1700 parts per billion (ppb), and N20 by 15% to more than 300 ppb. The growth rates in the concentrations of these gases in the early 1990s were lower than predicted; while subsequent data indicate that the growth rates are comparable to those averaged over the 1980s.

The pressure relief valves protect against the devastating effects of the overpressure. Unfortunately there are so careful with the environment and which are not always made leakproof, and can therefore be emitting harmful gases into the atmosphere continuously. While European directives aimed at reducing emissions of gases causing the greenhouse effect based on a share issue (linked to heavy fines for countries that fail), other solutions much easier go unnoticed.

Since the early 1960s, climate change and air quality have become major and often controversial issues in many countries and among groups from governments to various scientific communities. Prominent among these issues is the greenhouse effect, in which the gradually increasing tropospheric concentrations of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N20) are believed to trap an excessive amount of solar radiation reflected from the earth.
