Green technology is very new term and has been in news a lot more so since the international environment convention in may, 2008. Green technology is said to be the next big thing in environment after global warming. Environmental technology, green technology or clean technology as it is often put up as is basically the concept of using basic science along with environmental engineering and technology to conserve the natural environment, flora and fauna and counter any harmful elements which tries to disbalance this ecological balance. The idea is make the environment into a much better place to live with the use of science and technology while keeping the solution into the domains of socially acceptable, economically viable and practically feasible to implement.

The most often used Green technological advances are the ones which are now a part of most of our lives. The most common among them are recycling, water purification, sewage treatment, environmental remediation, flue gas treatment, solid waste management, and renewable energy. Apart from this any technology assisting in energy conservation and reducing the waste products shall be implicitly a part of Green technology. As a endeavor to produce energy form new sources which are more clean anaerobic digestion is used a new energy source so are hybrid electric vehicles. Green technology has now been used in green building to assist the basic architecture of the building, green computing is the new off shoring of green technology.



What are the raw materials of Green Technology?
As stated, nearly all Green Technologies rely on the use of new advanced materials. These new materials vary from metals commonly used today in many ways. First, elements on the periodic table such as copper, tin, iron and carbon are stepping aside in favor of less common metals, such as zirconium, yttrium, tellurium and the 14 elements that make of the group of metals known as the "rare earths". For example, batteries that were once made of lead are now made of lithium.

In addition to the use of new metallic elements is the use of these less common metals with common metals to form new super alloys with unique properties, such as scandium-aluminum alloy which can combine lightness, extreme strength and high temperature and corrosion tolerance in a single material. Another example would be newly developed carbides of various metals to create super hard and corrosive resistant materials with interesting properties. Similarly, the use of glass and ceramics in functional components of electronics and energy efficient systems is giving way to the use of crystal structures, semiconductors and super conducting materials.

What are the goals of green technology?

  • Sustainability - meeting the needs of society in ways that can continue indefinitely into the future without damaging or depleting natural resources. In short, meeting present needs without compromising the ability of future generations to meet their own needs.

  • “Cradle to cradle” design - ending the “cradle to grave” cycle of manufactured products, by creating products that can be fully reclaimed or re-used.

  • Source reduction - reducing waste and pollution by changing patterns of production and consumption.

  • Innovation - developing alternatives to technologies - whether fossil fuel or chemical intensive agriculture - that have been demonstrated to damage health and the environment.

  • Viability - creating a center of economic activity around technologies and products that benefit the environment, speeding their implementation and creating new careers that truly protect the planet.




IN the recent Grease stock an event held yearly in Yorktown Heights, New York more new GREEN TECH was presented like green wireless technology which included:
  • Energy efficient radio access networks --- by NEC

  • Energy efficiency enhancement in radio access networks --- by Ericsson

  • Cliffside and Atom projects --- by Intel

  • WiFi with the Bluetooth function --- by Ozmo

Though the Green tech is still very nascent as they have no central "neural form" of technology which is very needful to further grow the scope of the Green technology.

    Hi,
    Came across your blog while searching the net. Here are few slogans that you can use in your next post.

    It’s not easy being green.
    I’m a lean, mean, recycling machine.
    Reduce, Reuse, Recycle.
    I’m green, you’re green, we all love being green.
    The Earth: Love it or leave it.

    If you like to support the 'Go Green' movement in more that one way, why not check electric bikes that are environment friendly?

    Its nice to have your green slogans, sure we all love to be green on this lovely planet

    RENEWABLE AND EFFICIENT ENERGY
    HEATING AND COOLING BUILDINGS
    HEAT PUMPS
    www.geotermiaitalia.it/catalogo/prodotti.html

    > Geothermal heat pumps;
    > Air-water heat pumps;
    > Exhaust air heat pumps.

    They are energy efficient complete systems for heating and cooling which is both economic and environmentally sustainable .
    This technology is available both for residential single / multi-family and industrial and commercial buildings.

    The geothermal heat pump uses as a heat source the subsoil or ground water and allows a cost savings for the heating up to 80%.
    You do not need to reside in a thermal area to enjoy the benefits of underground heat: from 10 m depth the soil temperature remains almost constant throughout the year, and around 100 meters the temperatures are around the 10 - 12 °C constituting a heat source for the optimum operation of the heat pump.

    The air-water heat pump uses as a source of heat the outside air and allows a cost savings for the heating up to 50-60%.
    It can produce hot water for heating or sanitary uses up to temperatures of 65 °C with only the compressor and work up to temperatures of -25 °C!

    The exhaust air heat pump uses as a heat source stale air present in the house, allows a cost savings for the heating up to 50%.
