Transform the sun's energy

Transform the sun’s energy

Transform the sun's energy

The solar energy can be used in two different ways. As once did Romans Greeks and all the classic peoples who worshiped you can use the heat energy that gives us, so, with solar collectors of different types, heaters and concentrators can heat water, but not at very high temperatures, they can not overcome the 4000 ° k so that solar energy will not be useful when melting metals in blast furnaces etc. .

But some things can be achieved, depending on the ingenuity of the designer and the technological possibilities: To collect the heat energy from the sun several devices are used for flat plate collectors: flat plate collectors intercept solar radiation on an absorber plate by passing the so-called carrier fluid.

(This, in liquid or gaseous state, is heated passing through the channels by heat transfer from the absorber plate).

The energy transferred by the carrier fluid, divided by the solar energy incident on the collector and expressed as a percentage, is called instantaneous collector efficiency. The flat plate collectors generally have one or more transparent plates to help minimize heat loss from the absorber plate in an effort to maximize efficiency coverts. They are capable of heating carrier fluids up to 82 ° C and get between 40 and 80% efficiency.

The flat plate collectors have been used effectively to heat water and for heating. Typical systems used for home-room fixed collectors mounted on the roof. In the northern hemisphere they are oriented towards the south and south to the northern hemisphere.

The optimum angle of inclination to mount the collectors depends on the latitude. In general, for systems used throughout the year, such as producing hot water, collectors are tilted (the horizontal plane) equal to 15 ° latitude angle latitude and 20º S and 20º latitude orient N, using so more solar energy.

In addition to the flat plate collectors, typical hot water systems and heating consist of circulation pumps, temperature sensors, automatic controllers to activate the pump and a storage device.

The fluid may be both air and liquid (water or water mixed with antifreeze), while bedrock or an insulated tank serve as storage of energy.

Concentrating solar collector energy:

For applications such as air conditioning and central generation of energy and heat to cover large industrial needs, flat plate collectors do not provide fluids with temperatures high enough to be effective. They can be used in a first stage, and then the fluid is treated with conventional heating means. Alternatively, collectors can use more complex and costly concentration.

They are devices that reflect and concentrate solar energy incident on a small receiving area. As a result of this concentration, the intensity of the solar energy increases and temperatures receptor (called “target”) can approach several hundred or even thousands of degrees Celsius.

Concentrators must move to follow the sun if they are to act effectively; the devices used for this are called heliostats, mirrors that are mechanically moving or computerized control to reflect the maximum amount of solar radiation at the target.

Solar ovens:

Ovens solar energy are an important application of high temperature concentrators. The biggest, located in Odeillo, on the French side of the Pyrenees, has 9,600 reflectors with a total area of about 1,900 m2 to produce temperatures up to 4,000 ° C.

These furnaces are ideal for research that requires high temperatures in pollutant-free environments, for example in materials-research.

Central receivers of solar energy:

Centralized electricity generation from solar energy is developing. The concept of central receiver power tower or a matrix of reflectors mounted on computer-controlled heliostats reflect and concentrate the sun’s rays on a water boiler situated on the tower. The steam generated may be used in conventional cycle power plants to generate electricity.

The houses of the future:

Often speaks of smart homes, houses built and specially designed to reduce household energy consumption by focusing especially on energy saving and heat loss. These smart homes, for example have large windows facing south to heat inside in winter and some blinds designed to generate inside a refrigerated space in summer, without spending all electric or fossil energy for heating or cooling.

Also the walls are constructed from ceramic materials that keep heat in winter and in summer expel addition to using concrete tanks or water tanks to keep the heat for the winter night.

These small changes in our lifestyle as smart homes or use double glazing, insulate the house to avoid losses etc. to avoid the risk of passing as in photography; will make in the future global energy consumption is reduced considerably and so, like a domino effect, can save nature and our quality of life much better.

Black bodies:

As described in the introduction, and in relation to the previous point, there is theoretically what are called black bodies (bodies would be able to absorb all the radiation incidiesen upon him), that if someday encontrasen would be a invaluable as devices such as flat plate collectors and solar cells would yield very close to 100% and the scientists only have to worry about how to avoid heat loss and electric resistance and the like; the energy crisis would be solved, with solar energy solution.

The first homes in the UK that generates more energy than it consumes

The Solcer House in Cenin, Wales, was created as part of the Low Carbon Research Institute program. For every 100 pounds spent on electricity, this house will be able to generate 175 pounds in electricity “exports”.

L to first low-cost housing known as a house of ‘positive energy’, which can generate more electricity than its occupants may use, opened last Thursday in the UK.

The modest three-bedroom house built in just 16 weeks in an industrial neighborhood on the outskirts of Bridgend in Wales, costing 125,000 pounds and according to the designers of the University of Cardiff, will allow passengers to use the sun to pay the rent.

When using batteries to store electricity generated from solar panels placed on the roof and because of the thermal insulation, you may be able to export electricity to the national grid for eight months a year.

So for every 100 pounds spent on electricity, should generate export 175 there of according to Professor Phil Jones, whose team of Welsh School of Architecture project Solcer says specifically designed the house to reach the objectives the government proposed in 2006.

I also wanted to show that a house was perfectly feasible to reach the standard for affordable prices with current technology. So you pass the ball to builders demonstrating that, if you want, you can.

The cost of building a house of this type would be lowered if many be erected at the same time. Besides would be breaking that housing exported more electricity than they consume everything that it would. We must expect that the price per square meter in this house was given 1,430 euros, something close to social housing in Wales which lies between 800 and 1000 pounds.

Schlierberg, a German neighborhood where 4 times more energy than is produced is consumed

From the 70, Freiburg has been increasing its reputation and popularity as one of the ecological capital of Germany. In 1986 the city had a vision for sustainable programs that relegated better transport and energy efficiency are among the best in the world.

Schlierberg is one of their neighborhoods and have known that today generates more than 4 times the energy it consumes. A district that shows the way to become completely self-sufficient, because if now produce more energy than they consume, his goal is to be independent with new batteries powerwall Tesla.

As you might say, the future is there in front of us, we can only cross at him. Schlierberg consists of 59 wooden houses built with green materials in an area of 11,000 square meters.

Schlierberg, a German neighborhood where 4 times more energy than is produced is consumed

Among one of the virtues of this neighborhood and this city is that its inhabitants tend to move on foot or by bicycle, apart from solar energy available, reuse rainwater and use environmentally friendly materials in their buildings.

Freibourg Schlierberg, a German neighborhood where 4 times more energy than is produced is consumed

This neighborhood has in all homes with photovoltaic panels placed in the right direction to receive solar energy from the 1,800 hours of sunshine a year with. Freiburg, the city is among the regions with the most sunny days in the year.

According to Rolf Disch, the architect responsible for the project, the emission of nearly 500 tons of CO2 into the atmosphere is avoided. The houses are constructed so as to have a simple roof and wide eaves that allow the presence of sunlight during winter and protect the home during the summer.

One example to follow, and if we have that here in Spain we Huelva cities with more than 3,100 hours of sunshine a year, which we are not waiting. Just twice a region as referred to in this entry as Freiburg in Germany.
