As it is known, the progress in material goods production is uniquely linked to the success of the energy base. By the middle of the 21st century, when the population of the globe apparently stabilize on a point of approximately 10 billion people, energy demand per capita will reach about 105 kW • h per year, and the power of the world’s energy supply – 1010 kW. Today, world energy system is mainly based on non-renewable energy resources such as coal, oil, gas, peat or uranium. However, it is clear that we will not be able to achieve a substantial increase in energy consumption based on these resources as their stocks are limited, and because of the adverse effects of these fuels on the environment. So scientists have turned their gazes to solar energy long time ago. Some projects involve different methods of solar energy transformation into electricity in space, distribution and delivery of it on Earth.

The efficiency of terrestrial solar energy conversion to electricity depends on their efficiency and the annual number of sunny days. 20 years ago the efficiency of silicon solar cells was equal to 15%. The efficiency of today’s GaAs element with three transitions is 34%, while promising devices with four conversions will probably be of 42% (theoretical value of the efficiency of four-element reaches approximately 50%). Today, 1 kg of solar panels provides 300 Watts. Capital cost for the panels of solar cells production has decreased from $ 50 to $ 5 / W in comparison to 80s, and the cost of energy consumption dropped from 0.9 to 0.2 $ / kW • h.

To overcome the dependence on weather conditions the project of creation of space solar plant located on the HIS, was advanced in the late 70′s, with the transfer of power to Earth using microwave radiation to Rectenna (that is antenna with built-in rectifier). The project was being elaborated on all components of the system, but has remained as just an interesting suggestion: although the station would be able to transfer 10 GW, which is equivalent to the output power of 10 nuclear power stations, the cost of the components raising on the satellite would have been $ 22 / g, and the mass of the satellite would have been 90 tons. Today, the picture changed. U.S. experts proposed major developments of such plants in the 35th Conference on Energy Conversion (IECEC) in July 2000.

According to these experts, new technology involving the use of high-performance solar cells, high-power semiconductor converters and magnetron generators, is capable to reduce the mass of the station significantly. Reusable transport aircraft invented by NASA, will reduce the cost of the components lifting into low Earth orbit to $2,2 / g (that is to say, in future it can reach 88 cents / g). Satellite solar power can be raised from low Earth orbit to geostationary one with the ion engine, fed by solar panels. The concept of an integrated symmetric concentrator (ISC) will reduce the mass of the controlling and power distribution system on the satellite, which constitutes a significant proportion of the mass of the whole station.

I remember the controllers in gas masks working at the crossroads of Tokyo in the mid 60′s. Yes, negative effects of industrialization and urbanization have reached Japan earlier and more painful than other developed countries. However, a country of volcanoes and earthquakes coped with the new of her disasters called “Kogan” (that is to say, industrial pollution of nature) more efficiently than others.

The candidate from the progressive forces Professor Minobe won the elections of the capital governor under the slogan “For the clear sky over Tokyo!”. And he really kept his promise: he made sure that Tokians caould admire the sacred peak of Mount Fuji not less than once a week. And fish reappeared in the Sumida River that flow through the town.

With the steady growth of its productive capacity, Japan is making every effort to comply with its obligations under the Kyoto Protocol: to reduce greenhouse gas emissions by 6 percent in comparison to 1990 levels. We can speak about the following achievements in the topic when speak about Japan: for every million dollars of gross domestic product growth, harmful emissions into the atmosphere are 263 tons in Japan, while they are 606 tons in the United States and 2,538 tons in China. And above all – this is the result of “green energy”, the introduction of alternative sources of clean energy.

Surprisingly, but the state that had experienced the tragedy of Hiroshima and Nagasaki is among the leaders of the Peaceful Uses of Atomic Energy. In 70`s, Japan enacted 55 nuclear power plants, which produced more than a third of all energy consumed in the country.

Almost two-fifths of Japanese nuclear power plants have been operating during last 30 years. Some of them had failures, even with human victims. And once, the threat of radioactive contamination forced the evacuation of 200 thousand inhabitants in a radius of 10 kilometres.

There were also some warnings about the alarming fact that as a result of reprocessing of spent fuel, 8 tons of plutonium can be gotten. And this, as they say, is enough to make about thousand of nuclear warheads. But nuclear energy in Japan develops, playing in the life of the country equally significant role as it is in France.

Solar panels on the roofs
Japan is called as the Land of the Rising Sun. Its national flag is a red circle on a white background that embodies precisely this poetic metaphor. But the Far Eastern archipelago has earned another name. Japan becomes a land of the solar energy rising. After all, its share accounts now for about half of the installed capacity of all the world’s generators, which use sunlight. The share of the United States and the European Union is about one-fifth each.

In Japan, solar power is developing with the active support of the state, with the use of budgetary subsidies. And it is being pushed by its leading corporations in the field of electronics and high technologies. These companies have succeeded in the production of computer chips on the silicon basis.

It is a real gift that we live in the times when the government start to understand the value of living in harmony with the nature on this planet. And solar power grants is a realistic proof of it. If you want to switch to solar energy, please find out more about how solar power grants and how exactly you can exploit these solar power grants for your living.

The number of conflicts in the world that are caused by the energy needs increases today. Gradually, the amount of oil, gas and coal in the world decreases, and their consumption is increasing, particularly in developed countries. Most of them have spent their own stocks. And now, they are dependent on third countries that play on this and continuously raise the cost of raw materials that leads to higher prices, both on domestic and international markets. Accordingly, the problem begins with the socio-political situation. Governments of the largest energy consumers try to seize the places of raw materials extraction in order to avoid the crisis. It is not seldom leads to military conflicts.

Scientists estimate that hydrocarbon fuel will remain on the Earth during next 60 – 100 years, but it is a promising issue. At the moment the relevance lies in the fact that modern forms of energy change environmental conditions on the planet intensively, and unfortunately these changes are negative. The changes have become irreversible, and this often leads to casualties. Today the world uses over 12 billion kWh of energy annually. Such percentage is in materials using for energy production as: coal – 26 %, gas – 20 %, oil – 42 %, water energy – 4 %, nuclear energy – 5 %, and this leads to emissions of hundreds of thousands of tons of harmful substances into the atmosphere. As we see, we get most of the energy from fossil fuels.

Nuclear energy, which was considered recently as no alternative source of future, is almost at the top of the list of negative impacts on the environment due to constant threats of radioactive substances releases and as a consequence of long-term large adjacent territories pollution. Statistics show that almost all the energy is produced from minerals, and this makes 97%. And what is included in the other 3 %?

This is alternative energy – solar, wind, geothermal, installations that use the force of the tides etc. So the more and more attention and money are invested in innovative clean energy all over the world. The possibilities of solar energy converting into electricity` research and application in practice are being conducted extensively at this time.

Solar energy is the most environmentally friendly one and has infinite resource stock. Viability of this type of energy is confirmed by multimillion-dollar investments of oil giants such as UK-Dutch Royal Dutch / Shell Company, which has its research and development of alternative energy. It is going to invest amounts between $ 500 million to $ 1 billion annually in solar energy. Silicon is used for manufacture of solar cells. Because of the high cost of this material production, the first batteries were unprofitable. But we know that the progress does not stand still and every year the cost of it significantly reduces.

As for now, the payback of solar panels is more than 20 – 30 years, and the cost of 1 kW / m power obtained with the help of the sun’s rays is higher than that obtained from traditional energy sources. But solar energy is fully competitive in remote places or sites where electricity consumption is relatively high.

Be smart and use the aid of solar power grants to convert your life to enhanced ecological balance with nature. Read about solar power grants, how to use them and where you can get these solar power grants.

Vacuum tubes of ultrahigh thermal conductivity (SV-pipes) are work with the same principle as the ordinary vacuum tubes, and have all the above advantages. But they have some fundamental differences, which significantly increase their effectiveness. Not thermos flask is vacuumed in SV-evacuated tubes, but the entire space of the pipe that reduces heat losses to a minimum. As a result, they continue to operate efficiently down to -50 ° C

Because they use no double but single-glass, pipe wall thickness is increased on 0.5 mm, and it may withstand falling hail of 35 mm without prejudice.

With highly selective absorbent layer such pipes perceive diffusion light, and this means that they will work, even if the sky is overcast, they just loose productivity a little. They are ready to work immediately, as soon as the surface will be fallen with sunlight, and just 3-5 minutes later the temperature at the tip is raised to +100 ° C (maximum – up to +300 ° C). Performance of SV-pipe is about 85%.

Tubular Solar systems supply homes with hot water excellently. They heat swimming pools and greenhouses, make ventilation, air conditioning and heating of buildings work. Depending on the characteristics of the building solar collectors can be installed:

• on a sloping roof;
• on a flat roof or horizontal surface near the house;
• on a sloping wall, oriented to the south;
• be mounted directly to the roof.

The cost and accounting of the system
The cost of a solar collector installing exceeds the cost of equipment for the traditional heating and hot water, but the economic benefits of such solutions are obvious; if we take into account the constant increase in energy costs (for the last two years, gas has risen in price by 300%, and it is possible that we will pay for it at very high prices soon.

Systems are installed on a turnkey basis, that means that their value includes the cost of equipment and work that does not quite belong to the solar system itself, but which is essential to its normal operation (such as installing of battery tank and its binding). On the other hand, setting the heating boiler, the owners also have to pay for its installation. Another argument in favor of solar system is their long life. Solar equipment is very reliable – there are no moving parts, and therefore there is nothing that may break. Manufacturers guarantee that it will be successfully operated for 25 years. For comparison: the electric heater works about 6 years at home, and the boiler works 10 years in average (but you will need to replace the burner so that CPA not fall).

And operating costs are not comparable: Vacuum Solar systems require no maintenance (except the case when you will have to wash it if there is very strong dust). Boilers need to be continuously monitored. You must change the burner periodically, and heating elements in electric boilers. If the boiler runs on gas, you will have to deal with the gas department.

So, it might be not the worst idea to install the solar system in your household.

Luckily we live in the times when the government start to realize the value of living in harmony with the nature on this planet. And solar power grants is a real case proof of it. If you want to switch to solar energy, please find out more about how solar power grants and how exactly you can use these solar power grants for your living.

U.S. Internet giant Google is concerned about the lack of facilities for investment in environmental technology. It is also announced that the company is already developing a system that will allow reducing of costs for the construction of solar plants up to one-quarter. In 2007, the Google management board announced its plans to invest in the company and to conduct their own research in the field of alternative energy during further next few years. The relevant unit within the company focused on developing technologies for heliostats – solar stations, which use a system of mirrors for the storage of solar energy and evaporation of the liquid to produce steam, which then turns a turbine generator to provide energy.

According to current head of the company’s Ecoenergetics department Bill Vail, just now Google searches new materials for the heliostats to increase the efficiency of their performance and durability.

According to him, the company develops technologies, through which the construction of solar plants will cost a quarter less. Google plans to show them in a few months.

Usually, the structure of cost of a watt of energy capital costs amount to 2.5 – 4 dollars. That is to say, the installation of the plant with a capacity of 250 megawatts would cost between $ 600 million to 1 billion dollars. Thus, it turns out that the cost of electricity is 12-18 cents per kW / h.

Another trend, which Google also runs is technologies for gas turbines, which will run on solar energy, rather than natural gas. New ways will also help to reduce the cost of generated energy.

Within two or three years, the company will demonstrate a pilot grid of high-power scale, which can be used for mass production. With the help of the cost of electricity should be reduced to 5 cents per kW / h. Thus, the cost of alternative energy produced from the use of this system, decrease in 2.5 – 3.5 times.

In 2007, representatives of Google, announcing the program called “Renewable Energy Cheaper Than Coal”, which had the aim to reduce the cost of electricity below the price of coal per kilowatt – hour, indicated the following price horizon of alternative energy: the use of alternative sources of energy cost per kilowatt hour for the end user, ideally should not exceed 3 dollar cents. At the same time the company announced its intention to invest hundreds of millions of dollars in the development of methods of solar power production, so as wind and other forms of energy from alternative sources.

The company had to invest about $ 50 million in the program on alternative power over the past two years. These funds were invested in, including in dealing with solar energy company eSolar and BrightSolar, which, however, are not engaged in the development of equipment and mirror systems for solar plants. Generally, there are not so many companies that operate in the field of alternative energy.

In recent years the market of solar energy has been growing up to 30 % annually. According to research of firm called Lux Research (USA), the total size of the solar energy market in last year amounted to 33.3 billion dollars, or about 5 GW.

We continue speaking about the tube solar power collectors.

Due to the fact that the coolant flows directly through the pipe in the reservoirs they have, there are difficulties in the installation. Each tube should be connected to the system separately in order to avoid leakage of coolant. We need also serious maintenance, because leakage or mechanical damage even of one tube stops the work of collector. The vacuum tube consists of two glass tubes: outer is made from ultra strong transparent borosilicate glass that can withstand the impact of hailstones with a diameter of 25 mm, internal one is the same but with a special selective coating (A1-M/A1) that ensures excellent heat absorption with minimal reflection. In order to avoid conductive and convective heat loss from the space the air is exhausted between the two tubes.

To maintain the vacuum barium gas absorber is used, which is exposed to high temperatures in a production environment, resulting in lower end of the vacuum tube is covered with a layer of pure barium. It absorbs CO, CO2, N2, O2, H2O and H2, which are distinguished from the tube during storage and operation, and is a clear visual indicator of the vacuum. When the vacuum disappears, barium layer transforms into white from silver. This makes it easy to determine whether a pipe works correctly.

The absorption of heat occurs in the copper heat-pipe, which is located inside the vacuum tube. Method of heat transfer from its thermal conductivity is very simple.

Copper tube is hollow and contains a patented inorganic non-toxic liquid. When heated, the liquid evaporates, and because of the vacuum created inside of a tube, it occurs even at a temperature of 25-30 ° C.

The vapor rises to the tip (that is to say condenser) heat pipe, which gives off the heat to water, which flows through the thermal conductivity. Then it condenses and flows down, and the process repeats again.

Solar collector with vacuum tubes shows excellent results on cloudy days, because the tube can absorb energy from infrared rays that pass through the clouds. With insulating properties of the vacuum influence of wind and low temperatures on their work is so insignificant in comparison to the impact on the flat solar collector. The system works successfully down to -35 ° C. Packed tubes are round, so that the amount of solar radiation reaching the collector remains fairly constant from mid morning until mid-day. This brings increasing in the total amount of absorbed solar radiation. The shape of pipes provides superior degree of absorption, since the sun’s rays always fall on its surface at a right angle, reducing the reflection to a minimum.

Pipes are laid in parallel inside the collector. The angle of inclination depends on the latitude of the place. Having been oriented from north to south, they passively follow the sun during the day.

This collector requires virtually no maintenance. Manufacturers offer the guarantee up to 25 years for similar products. The system is fully maintainable: if necessary, the pipe can be replaced, added or removed without stopping of the collector.

Luckily we live in the times when the ruling elites start to realize the value of living in harmony with the nature on this planet. And solar power grants is a realistic proof of it. If you want to make a switch to solar energy, please find out more about how solar power grants and how exactly you can exploit these solar power grants for your living.

The main component of the flat collector is a copper absorber with selective coating, which provides a high level of absorption of solar energy and low emission of thermal energy. Copper tube is installed at absorber and coolant flows through the former. It may be water or some non-freezing liquid, which takes heat from the absorber and simultaneously with circulating through the coil, it accumulates in the accumulation tank (the tank with water).

The absorber body is protected by a collector with a reinforced insulation that also minimizes heat loss. The amount of solar radiation that reaches the surface of the solar collector reaches its maximum only at noon when the sun is at its zenith. Speaking about morning and evening, sunlight falls on it at an angle, and the amount of absorbed solar radiation decreases.

Flat collectors do not work in winter, because even with a two-system` antifreeze, the maximum allowable operating temperature is about -5 ° C. With further lowering loses of heat reduce the result to a level of zero. The more solar collectors absorb solar energy and the less they lose it, the more efficient the system will work. Efficiency of the collector shows what percentage of solar radiation that falls on its base surface, can be converted into useful thermal output. This indicator is volatile and can be determined only in the specific operating conditions in a single moment in time. The lower the temperature to which you want to heat the water, the more efficiency is. Modern flat solar collector work with an average working efficiency of 50%, more obsolete models work with 20-40% of it.

And now we will compare flat collectors with those of high-vacuum tubes type. Their employment is based on a simple principle of a heat pipe, which is a hollow brass rod, soldered at both ends with the extension in the upper part. Non-toxic reagent is inside of it; it evaporates during boiling and in the form of vapor rises into the upper part – into the tip, where the temperature can reach 250 ° C. And it is condensed there, giving warmth, and condensate flows down the walls of the tube, and the process repeats then.

Heat removal can be carried out in different ways, for example, directly from the tip through the glass, soldered to the pipe through which the solar fluid flows. In a closed-circuit it can be freezing liquid-based glycol (warmth comes to storing tank), in an open system it may water (it goes directly into the boiler). Whatever it were, immediately after the absorption the heat is given to the coolant and does not go into the environment. This is the key difference between heat pipes and flat solar collectors.

The effectiveness of heat pipes with U-shaped tubes (the most simple, used in tubular systems) is a cut above that of flat collectors. Due to its cylindrical form, they work fine during the day, because their surface is always illuminated by the sun. This results in a stable energy at different angles of incidence of sunlight. The tubes are well protected from the adverse effects of nature (hail, wind and other things), but in any case, such systems also have weaknesses.

You do not have to pay for solar energy, because it is effective and virtually inexhaustible. This is a really sufficient reason for considering of solar power as the most promising alternative means of low-potential heat energy obtaining, isn’t it? Through the use of modern solar energy technology during the period between April and October, you can opt out of the gas and electricity consumption for hot water, and during the winter months you may use this to save amounts from 40 to 60% on energy carriers.

A solar collector is the main element of any solar system. Particularly in its absorbing panels or tubes solar energy is being converted into heat. The coolant (it is usually a non-toxic freezing liquid) selects the heat and, having entered a heat exchanger tank battery, it transfers heat to water. Water is used for hot water supplying or in order to maintain the warm in a household, and chilled coolant returns to the collector, and the process repeats then. It lasts until the sun sits down. Modern highly selective coatings allow the system to work, even if the sky is overcast.

The water, which is then used for household needs flows in the simplest single-circuit systems. However, the exploitation of such reservoirs in our country is complicated by a number of reasons. Firstly, their channels may be soiled with salts because of high water hardness. Moreover, freezing temperatures happen even in late spring or early autumn. It causes the water freezing. Therefore, dual-circuit system is preferable to be used in our climate.

The coolant can circulate in the collector disk in a natural way (by heating and rushing to the top of the collector) or with a circulating pump, power consumption of which is negligible in comparison to the generated heat. Systems with coolant natural circulation are widely used in countries with warm climates and a large number of clear days (eg, in Turkey, Greece, Egypt, Israel). In our climatic conditions systems with forced circulation are more effective ones.

If there is enough large amount of solar energy to heat water, for space heating or water heating in a swimming pool, the collector is often combined with other heat generators. For example, in the bivalent plants the extra heat could be given with hot water boiler that runs on liquid or gaseous fuels. Such a system solution allows provide homes with heating in winter.

Flat solar collectors are widely used today. They work well under normal solar intensity in the period from May to October, and, moreover they completely override the need for hot water in summer. In our climatic conditions, such systems are ideal for a summer home or seasonal home stay. Relatively low cost is their unquestionable advantage.

The building of a modern flat manifold is a frame, which is made of galvanized steel or anodized aluminum, in which hail-stainless sheet of glass with low iron content (0.03%) with a thickness of about 3 mm that allows reducing of heat loss is hermetically inserted.

Alexander Edmond Becquerel opened the photovoltaic effect in far 1839. In 44 years Charles Fritts managed to construct the first module that could use the solar energy. And selenium coated with thin layer of gold served as the basis then. Scientists have found that this combination of elements makes it possible, albeit marginally (about 1%), to convert solar energy into electricity.

Every day brings many pleasant and not very pleasant surprises to the evolution of humanity. We must pay with something for every progress peak` conquest. All of us know from school the truth about the limitless nature of human needs. Their implementation requires an incredible amount of resources, which are not infinite. Daily, it prompts us to seek new ways to recharge our values that are necessary for the existence of a one, and for pleasure of another. And the issue here is not just about luxury goods, but also about the simple means of life maintaining for each of us. Let us speak, for example, about electricity. Unfortunately, today people no longer notice its absolute dependence on electricity, and hence on its sources, which sometimes simply let us down at the worst possible moment. A striking example is an accident at power plant, when the town is without electricity during few hours. Panic fear, light torches and total helplessness – that is what it means to be without the support of energy for an hour or two. It is a pity, but the person does not always have time to think what would happen next.

In the second half of 20th century the planet’s ecologists became seriously concerned about the problems related to conventional means of electricity production. The problem was the destruction of ecosystems by hydropower plants and nuclear plants waste disposal. In addition, a situation was aggravated by the fact that reserves of fossil fuels (such as oil and gas), by leaps and bounds growing prices, in a couple of decades may dry up altogether. a Major study conducted by analysts and researchers may proof this:

Oil will be the first fuel to be over. There is as huge amount of oil, which is being consumed all over the world annually, as it is formed in natural conditions within 2 million years. We will have enough amounts of Uranus during nearest 64 years, and, fortunately, our grandchildren and even great-grandchildren will be able to use coal.

Natural disasters and climate anomalies have finally confirmed the fears of experts. A man has finally understood that has to look for another way. And let the first technology will be expensive, not as effective, yet safe for nature. Among the many proposed options of transition to a “safe energy”, particular importance is attached to solar energy by scientists. Why?

To find the answer to this question, we must try to figure out whether the solar energy has any opportunity for the future or it does not, what the prospects for the industry are, what is actual the transition to the “solar” technology with in our time for individual consumers.

It is a real gift that we live in the times when the ruling elites start to understand the value of living in harmony with the nature on this planet. And solar power grants is a real case proof of it.

The Sun is the source of life and hard killer simultaneously. It gives the opportunity to be born and grow up for every living organism on Earth during several billion years. Man began to think seriously about sunshine “taming” technology only in the last century. The question how to make the sun work for us, how to make the process of the sun’s rays energy extracting simple, cost effective and cheap?

The year 1883 is considered to be the year of the solar energy era birth. However, not all people think so. There is a perception in the scientific world that the “father” of the solar energy epoch is the great Albert Einstein. In 1921, Einstein was awarded with the Nobel Prize. Many people believe that a great scholar of 20th century was awarded due to his rationale formulated theory of relativity, but it is not true. It turns out that the physicist got the prize for an explanation of the photoemission laws.

Over a hundred years a man could see a development of the industry experienced sharp rises of private and public institutions investment that were stimulated with scientists. But the history knows the bitter falls, that prompted the society to forget about “solar technology” for years.

Is solar energy ideal from a technical and economic point of view? Unfortunately, it is not quite. We will try to highlight the main advantages and disadvantages of this extraction of energy method.

Let us start with the positive sides. Firstly, mention that the “raw”, that is to say sunlight, will never end. Another advantage of solar energy is its accessibility, as the sun shines in the south and west, in Africa and Europe.

There is the controversial question of absolute security of these technologies for the environment. Of course, it is not a nuclear power or oil and gas. But at this stage of the “solar” technology development, harmful substances are used in manufacture of a battery, which in any way can harm nature. Ready-made designs (photovoltaics) contain toxic substances such as lead, cadmium, gallium and arsenic.

With regard to the life of transducers (30-50 years), the problem of the subsequent processing of its obsolete modules arises. And the problem of their utilization has not yet been solved. The obvious disadvantage of the process of extraction of energy is the so-called variability. The solar system is not able to work at night; and the effectiveness of the stations fall for several times in the evening and within morning twilight.
