    space heating and cooling system. Solar process space heating system will provide large quantities of hot water for household uses. Besides that‚ the solar energy also can use for cooling system that combined with some very complex chemistry tricks to create the cool air. The solar energy also can be used for photovoltaic systems. It uses solar panels to convert sunlight into heat‚ applies it to a steam generator and then converted it into electricity in order to warm the buildings‚ heating the water

    and development of the company Production of electrical heating elements has a more than fifty-year tradition in Hlinsko. In 1943‚ a small joint stock electrotechnical company ESA was founded. It started with production of small household appliances‚ namely cookers and irons‚ where resistant spirals of own production inserted in ceramic base were used. In 1948‚ a licence of a Swiss company Maxim-Aurau for production of sheathed tubular heating elements of flat-oval cross section has been bought. This

    acquire solar energy. This is because it relies on the infrastructure of the building. Architectures today are offering a “solar design” option to clients‚ where the building can be made to receive optimal sun radiation to get solar lighting and heating. The ventilation system would be designed to compliment this system. Using this system can potentially reduce temperature by nearly 3 °C at an estimated cost of US$1 billion‚ giving estimated total annual benefits of US$530 million from reduced air-conditioning

    oceans and the atmospheric circulation such as in Figure 1. This is due to the density differences between air masses because of the uneven heating on earth from the sun. The global atmospheric and ocean circulation will change but it would still distribute the heat between the poles and tropics as it does now. But because the Earth rotates‚ it causes winds to curve due to the Coriolis Effect. This breaks the two large atmospheric air circulations into six smaller cells shown in Figure 2. If earth rotated
