Radiant Barrier Paint Stops Heat Saves Money
What is a radiant barrier? Radiant barriers are materials of a highly reflective material, usually aluminum, that are installed in buildings to reduce summer heat gain and winter heat loss, and hence to reduce building heating and cooling energy usage. The benefit of attic radiant barriers is primarily in reducing air-conditioning cooling loads in warm or hot climates.
How do radiant barriers work? All materials used in building construction brick, stone, asphalt, paper, and so on ,regardless of their color, absorb and then emit, (give off), thermal heat. On a sunny summer day, solar energy is absorbed by the roofing materials and roof sheathing, temperatures can reach as high as 160 – 160 F. This absorbed heat radiates downward toward the attic floor. When a radiant barrier is placed on the underside of the roof sheathing, much of the heat radiated from the hot roof is reflected back outside. This makes the attic insulation cooler and thus reduces the amount of heat that moves through the insulation into the rooms below the ceiling.
Solar Plants Light Up Australia
With as much potential for the development of solar energy that exists all around Australia it is no surprise that the nation has had big plans recently for the renewable energy type. Over the years, Australia has developed a fairly sizable solar energy program with substantial government support backing the developments. As evidence, recent news coming from New South Wales has been detailing that the government’s support will be used to create one of the largest solar energy farms the country has seen yet.
The new solar energy plant in New South Wales is expected to, upon completion, boast a capacity of around 100 megawatts and power approximately 20,000 homes in the area. The farm will be built by Infigen Energy, which has numerous wind energy projects around the globe and in Australia, and Suntech Australia in a joint effort that is expected to cost around $300 million (That figure represents the Australian dollar which currently holds a conversion of one dollar = ninety nine cents American) and will utilize the national fund for the development of solar power in order to cover $100 million on the final price tag. Once completed, the plant will supply the 100 megawatts of solar energy directly into the grid.

Next week, four experiments designed by high school students will take to the skies aboard a weather balloon in a NASA competition.
The four science projects will launch on May 19 from Upper Sandusky, Ohio, as payloads in a NASA-built helium weather balloon. The balloon will soar to the stratosphere, about 20 miles (32 kilometers) above the Earth’s surface, in NASA’s second Balloonsat High-Altitude Flight contest.
10 Interesting Facts about Batteries
10 Interesting Facts about Batteries
We seem to take batteries for granted these days, barely giving them a second thought. Most gadgets need batteries in one form or another, and most batteries are not great for the environment. Rechargeable batteries reduce the number of one-use batteries that we use, but rechargeable batteries still use harmful materials.
What is Wind Energy – Wind Power – Turbines
Types & Structure of Wind Turbines The wind turbines have three basic components, The Mast, a Rotor and a Pod. The mast is made up of steel and it is foundation on which other components of the wind turbine work. It is inserted into the soil and a solid concrete base supports its unyielding grip. The wind turbines are installed very high in the air in order to utilize the very high wind pressure. Wind mills are almost 80m to 100 m tall. The purpose of implanting high wind mills is to receive uninterrupted wind pressure at all times. The rotor on the other hand holds the blades of wind mill. These turbine blades are made up of material which has strong resistance against changing weathers. The material which is usually used is fiberglass or carbon fiber. It is this rotor which converts the kinetic energy of wind into mechanical energy for further uses. If the mechanical energy is sued to support cutting of woods it is termed as windmill. However if this mechanical energy is converted to electricity it is known as wind generators. The pod third and last important component which helps the rotor wings to convert the kinetic energy into electricity.

Why Should You Choose Solar Power? 
Life on earth is fueled by the light and heat from the sun.
Approximately, 3850 Zettajoules (ZJ) per year is the total amount of solar energy available to the earth. The suns energy travels to the earth by way of electromagnetic radiation like radio waves but the frequency range is different. Some of this energy is absorbed as it comes thru the atmosphere. Heat and light are the primary forms of solar energy.

Solar panels
Many plants are heliotropic, gradually tilting towards the sun to optimize solar energy capture. Current sun-tracking solar panels involve the use of motors and electronic control systems, but we believe a biomimetic heliotropic solar panel can be created with the use of alternative materials and designs. Practically, the heliotropic solar panel could be useful in developing areas, where motor-based sun-tracking panels are not affordable. From an expressive standpoint, a solar panel that tilts towards the sun (like a sunflower) can help the public see a connection between the natural and the high tech. Solar cells that track the angle of the sun can be 38 percent more efficient at generating power than those that are mounted in a fixed position.
A team of three MIT students (Forrest Liau, Vyom Sharma, and George Whitfield) designed such a system. Their team, called Heliotrope, won top honors and a check for $10,000 in the finals of a competition aimed at developing innovative energy technologies.
They designed the system that imitates the way plants track the sun across the sky, by using the difference in temperature between shaded and sunny areas to change the properties of the material supporting solar photovoltaic cells. Unlike the systems which are currently being used the biomimetic system, once built, is completely passive, requiring no power source or electronics to control the movement. The team explored several different variations of the proposed system, using various materials including polymers and bimetallic strips. The system that shows the most promise, they said, mounts solar panels at the top of a curved arch made of a pair of metals such as aluminum and steel, which should be durable enough to withstand the elements with little or no maintenance.
German National Holiday Celebration Features Local Renewable Energy Industry
German National Holiday Celebration Features Local Renewable Energy Industry 
Top renewable energy companies present in eastern Germany (the former East Germany) will have representatives on hand. by Staff Writers Washington DC (SPX) Sep 28, 2007 By the year 2020, Germany will be the number one country worldwide in renewable energies. The country already possesses the world’s largest market in photovoltaic (PV), wind energy, and biodiesel. This is the result of groundbreaking innovations, smart policy, and favorable investment conditions. Displays of German innovations in renewable energies and other industries will be part of two events open to journalists on October 3rd, the German National Holiday, in Washington, D.C. The day celebrates the reunification of Germany on October 3rd, 1990.
The first event is a Business Luncheon at the Rooftop Terrace of the Hey Adams Hotel at 12:00pm. Speakers include political and business leaders, including Wolfgang Tiefensee, Federal Minister for Transport, Building, and Urban Affairs, and Commissioner for Eastern Germany, Heinz Haller, Executive Vice President for Dow Chemicals, Andreas Dressler, Director of KPMG, and Michael J. Ahearn, CEO of First Solar, Inc. First Solar is an American solar cell company that recently opened a manufacturing facility in eastern Germany.
