Now Solar Energy from Space to Earth

Space engineers plan to put satellites into orbit that can collect large amounts of energy from the Sun and convert it into a infrared laser beam transmitted back to Earth as an alternative to the planet's fast-disappearing energy sources.
Expert at EADS Astrium, Europe's largest space company, are working on a small demonstrator of a full sized space-based power station, a network of which could meet demands of electricity 24*7.
There are global need for increased energy generation that does not have an environmental impact, the British newspaper Daily Telegraph quoted matthew perren, head of innovation at astrium's headquarters in Paris, as saving.
" The real advantage of space solar power is that it can provide power on demand as we can essentially point the laser beam wherever we like on the earth below the orbit.
"Looking to the future we envisage large power stations in the space that are capable of transmitting energy to any point in the planted on demand,"

Portable Solar Charger Helps you Go Green


As the world has started planning to go Green and check pollution rise, the portable solar charger can help us in our effort. this type charger get fast charging mobile device and as well as save electricity till 95% so you can make yourself self relevent person.The free loader portable solar charger is equipped with a system that can charge any hand-held device any where in the world where there is sufficient sun light. With these solar energy you can make several device by which you can revoulnised where you are living at this time.. you can change your life with twenty four hour light systems. It has got a set of solar panels with a USB backup. If fully charged, i can power an iPOD for 18 Hours, a mobile phone for 44 hours, a psp for 2.5 Hours and PDA for 22 hours.

Now generate Solar energy at Earth

Let the generating energy from The sun at Earth is the time of repeation. for this purpose project has been started in France for building fusion energy reactor. India too getting involve in this project. its a joint International work. The eater India Agency has been form for its implementation. The Assistant of Energy research establish pact between india and European Union.
Fusion energy research is known as International Tharmo Nuclear experiment Reactor
Its responsibility of itear company to eastablish this project in kandarash . Due to this project Vocume vassal, high voltage power supply, cooling water system and other related instrument may be supplied.

Energy fusion process in The Sun is the solution of nuclear . And through priciply it is proves that this process can repeat at Earth. If it succedd the problem of electricit and energy may resolve at the Earth. So due to this process You can reduce your electricity and build your own solar power systems.

The Use of Renewable energy for The World

Green energy proponents are looking for a major policy boost to the sector, One that will significantly increase the use of renewable energy source for energy generation, including in the transportation sector. They are hoping for a transportation sector from an also-ran to one that will contribute in a major way to country energy's security. they feel that although the electricity act, has dealt with power from renewable energy sources, a lote more needs to be done .

They argue that separate legistation for renewable energy is is a must if the sector is to get a leg-up . In their defence, they point to Germany, which has made remarkable progress as for as green energy is concerned thanks to significance piece of legislation that was enacted in 2000.

Please Find more Information... Soar Power Systems
Renewable energy installed capacity in the country at 10,175 MW (at end-September 2007) in 7.5 percent of the total installed generating capacity of 135781 MW, while the actual electricity generated from renewable will be for lower in percentage term. of the installed green energy capacity wind energy alone accounts for 7200 MW or 70 percent , with other green renewable source such as biomass, small and mini-hydro, combined heat and power making up the balance. Those pushing for greater role for the green energy sector want the government to set ambitious targets and specify that electricity from renewable energy sources should contribute more and more.

Wind Generating Energy Resource

Wind an example of useful source of energy produced by the gigantic climate engine run on solar energy. Wind generators set up at suitable locations could be used to generate electricity . already several wind farms for generating electricity have been set up in world. but more need to be done.
Ocean tides are produced by the gravitational pull of the Sun and the Moon. They can be used for generating electricity. The french have made efforts in this direction and they have built a tidal power station in the southern coast of France. Many suitable sites can be found for such plants on the long coastline of the India.

Oil-bearing plants like Jatropha and sugarcane waste (bagasse) are valuable resources that could be used for producing Diesel by chemical process. Such bio-fuel can be used for running motorcars and autos. Jatropha plantations are coming up in many states like madhya Pradesh and tamilnadu and on wastelands along railway tracks. Bagasse is being converted in to diesel in India.

How to Gather hydroelectric power from the Sun.

It took nearly 500 million years for the formation of the present coal and oil deposits. but the extravagant humans of the twentieth century have deplated them so fast that the entire coal reserves would barely last for another 100 years. wood can be grown by reforestation, but the process is very slow and inefficient. Actually, the area under the forests is already diminishing due to the growth of urban areas, industrialisation, road building, etc. So one has to look for alternate sources of energy.
Hydroelectric power from the river dams is indirectly derived from the Sun. It is the heat of the Sun that vaporises the water of the oceans that ultimately cause rain to fall and fill the reservoirs. Water stored in dams is then used both for irrigation and producing electric power. However, hydroelectric power can augment power supply only to small extent, and building of dams has been linked to environmental problems. Even in developed countries hydroelectric power accounts for only two per cent of total power supply.

Solar furnaces and solar distillation plants


Solar heat has been used since times immemorial for drying of foodstuff like grains and fish, and for extracting salt from seawater near seacoast. Solar thermal energy refers to the utilization of solar energy by capturing the available solar radiation and transferring it as heat perform various useful activities, like, heating, cooling, drying, water purification, industrial process heat and power generation. The first deliberate attempt to make the Sun do some work for humans is reported from about 2,000 years ago. Like many useful inventions it was the result of a war. It is said that in 212 BCE, when the Romans attack Greeks, The Greeks scientist Archimedes was able to set fire to the Roman ships at Syracuse by focussing sunlight reflected from mirrors set in circullar arc. This idea remains domants for 1800 years. But in the 17th, 18th, 19th, ceturies several scientists in Europe made attempts to melt metals by focussing Sunlight by means of large convex lenses and concave mirrors. All metal including silver, gold, copper, and even platinum having a melting point at 1769 degree celcious were melted in this fashion. These were mostly scientific experiments, exception being a solar furnace built by famous steel make Bessemer. His furnace had diameter of 3 metres in which he melted copper and zinc in 1868.
