The Days | RENEWABLE ENERGY

Energy Day or National Day of Energy - The day, month or year is not very important because every day, 24 hours on 24 hours we all energy consumption. The stories that are emerging daily on the fuel increases leading companies and the preoccupation of the populations. Everything revolves around the price of oil because the whole industry and also the final consumer is dependent on these sources, either in fuel or in elecrticidade. And the increases also focus on essential goods of every day, such as food and all products of first necessity.

But this is a reality worldwide. We can not escape the idea that we are dependent, import more we export. To reverse the escalation of prices, up to the industry in general and the civil population reacting. React in an intelligent way, using all the tools we have. The most important tool that we have is the savings. On this Day of Energy made a gesture for all of us:

- Replacing a light bulb in a lamp saving.

- Help elderly people to do this if the facility did not get it done.

- Enter a liter and a half bottle of water (full of water) in the flush, each time you use will save 1.5 liters.

- Turn off the stove or oven moments before you finish your meal.

- Properly regulate the temperature of the refrigerator or freezer.

- Check the power consumption of each equipment that will buy.

Could list more ways to save energy, we will do it on a regular basis.

The first factory specialized in the production of heaters and appliances for kitchen fed with solar energy, came into operation in Kukara (Soviet Republic of Uzbaquistão). Within a few months will be ready to inhabit two buildings of apartments, three floors each, in the warming of waters and air conditioning shall be provided by the use of solar energy.

Replacing the fuel by solar energy for heating of houses is now to guide the work of heliotécnicos Soviets.

The two buildings of apartments already built in the Soviet city of Tashkent and Tchirtchik have a curious facade. They remember a chessboard on which the boxes are black and white, respectively, to the windows and metallic devices that heat the water at about 70 degrees centrígados.

Previously, the heating installations were placed in the roof, but in this case the heat was revitalized only for the consumption of small houses. The new technical solution of Uzbek allows the construction of large buildings "sun" that will help save 60% on the fuel used in central heating and water.

The solar kitchens have a device composed of six "petals concentrated" silver, which are giant flowers and remember that focus the sun's rays at a point where the receiver of solar energy. With a clear sky, the days with sun, Central Asia, are about 300 per year. These kitchens work as well as those powered by electricity. The heliotécnicos are currently under study projects for solar installations for refrigerators, dryers fruit, wheat, vegetables, cultivation of silkworms and silk articles of glasshouse of reinforced concrete.

Transform solar energy into electrical energy is another of the objectives of the current work of Soviet scientists. They intend to achieve this conversion with the help of the engine "Stirling". Any source of heat is allowed to operate such a facility, but the source is perhaps more rational use of the sun. They are already prepared projects for solar power in that its operation is based on circulating in a closed-circuit gas hydrogen or helium, for example, which triggers the engine bender.

Solar energy finds multiple applications in the field of agriculture and livestock. In the deserts of Central Asia was made to a desalination water underground minerals, which contributed to further development of livestock breeding in this region. Experiments done in the planting of cotton showed that an irradiation of seeds of cotton, before being thrown to the ground, increasing its yield by 10 to 15%.
