Environmentalism is the thought of about all of us these days. This is due to the fact that pollution is increasing at a frightening pace and is setting undue amount of strain on the delicate balance in nature. When this balance is irrevocably broken it is very not easy for our planet to carry on being a “paradise”. So scientists are searching for substitute mines of power besides fossil fuels like petrol, coal etc. Sun is the renewable source of energy that is generally accessible in great quantity and the energy potential from it is literally limitless. Solar power has therefore assumed a great degree of value today. The benefits from such an endeavor are numerous, and can include things that will help humanity for many years to come. A cleaner planet is something that many people see as important for our lives now as well as the future generations that are to come, and thus, implementing solar energy into our daily lives has become very important.

There are two techniques used in the process of obtaining of solar energy – one is the active method and the other is the passive method. In the active method photo voltaic cells or heat engines are used to accumulate the sun’s heat energy and change it into a type that is usable for several purposes like for example current to run lights. The photo voltaic cell as the term shows is an apparatus that is applied to change light/ heat into current. When used as a single element has the capability to run a watch or a calculator. When it is used as a large set it will be able to generate adequate power to run a home.

In the passive method an edifice is constructed in such a manner as to use sun’s energy to the limit. For example windows are built in considered locations where they are expected to harness the sun for a prolonged time and sun roofs are made which can carry on a room properly lit and warm too. The equipments used also hold characteristics that are unique like having a certain thermal mass or light reflecting capacity and so forth.

For instance you are moving to a home which is sunny. You may be attracted in knowing whether you can swap to utilizing solar current there – what are the functions you can put it to, how much economical it will be and so forth. On top of that you may as well wish to avoid moving stress which are the usual pressures connected with relocating a house. You could approach cheap movers who will assist to make your relocation uncomplicated. If you own a car that you want to bring along to your current home you will possibly need car shipping quotes too. When these logistics are all finished, you can concentrate on setting the sun’s abundant energy to apply for every day functions like cooking, heating water and so forth. You may even want to design your current place to catch the sun to the extent probable to maintain your interiors sufficiently lit and fresh at all times.

With the ever increasing concern for going “green” and rising energy costs, more and more people are considering how to harness the power of the sun to our benefit. This article is an interesting timeline if solar power and the evolution of solar powered products.

Solar cells are commonly referred to as devices that capture the sunlight’s energy and convert it into energy. Solar panels and solar modules are prime examples of solar power. Although this power source is efficient in capturing energy, it is costly to produce.
Enter Nanoantenna, a future hopeful in solar cell replacement, made up of small gold spirals or squares set in polyethylene, the same material used in plastic bags. Although still in the testing stages, these nanoantennas are believed by experts to be able to capture up to 92% of energy at certain infrared wavelengths. Using infrared rays, they can continue to collect energy even after the sun has set. This energy can be harvested at all times, not just during daylight hours. Considerably more affordable, the nanoantennas are based on inexpensive plastic sheets.
Scientists at the US Dept. of Energy’s Idaho Laboratory are still searching for ways to convert the captured energy from the nanoantennas into electricity. There is still considerable research ahead to be able to transfer this solar energy into usable electricity. However, scientists and researchers are hopeful that a bright future in solar products is just around the technology corner and that tomorrow’s electronics will be powered by a less expensive solar powered product.

photovoltaic cells, makes use of sun energy and environmental sound and clean for collecting solar energy. Here is a product of solar panels has been explained that is solar charger, Charger which are specification of silicon plate with 5.5 volts, Mono crystalline silicon or poly silicon, the efficiency of conversation is 16%.

It’s protection function is over current, over charging, over discharging and short circuit. There are lots of products of solar panel which are created by sunlight and cost less than the electric devices

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 ruling elites 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 make a switch to solar energy, please read more about how solar power grants and how exactly you can use these solar power grants for your living.

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 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 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.

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.

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.

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

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.
