March of the Green Technology

 

Technology has been defined in several ways. The simplest is the knowledge of using tools and techniques to improve the working condition, organizational management and artistic perspective in order to enhance the efficiency of product, machine or human initiatives. The primitive man is known for intelligent utilization of stone to convert it into weapon and shelter houses. The usage of animal skin and bark of trees for covering body was a step towards fabric technology. The knowledge of technology to control the fire radically changed the status of man learning to add new items in his food menu and getting warmth in a cool climate. The wheel has brought us to the present state of global conveyance Flinging of leg bones into the space after a good and hefty meal inspired space odyssey. Information technology spear headed by internet has its origin in smoke signals and more recently to printing presses. Now we have industrial, educational, information, medical, visual, micro, nano, and domestic technology to name a few.

Technology is not singularly applied by human kind to give impetus to his objectives. The pets and birds have also excelled in carving out technical wonders comparable and occasionally better than us. The nest of the weaving birds, indicators from dolphins, breaking of coconut shells by monkeys, domestic technology of ants, technology of descent from an acute slope by elephants, migration of birds to areas akin to their need and requirements, waiting for surroundings to become sizzling before taking to a trip by kites and various other heavy size birds and dropping of stone pallets to raise the drinking water level in a narrow necked pitcher by crows are some to refresh the storage. Look towards the sky in the evening. You shall discover ducks flying in inverted V development, giving others the advantage of vacuum and stream range motion.

There is a difference in how the primates of yester years behaved, how animals and birds around us make use of the technology and how we are using it. The difference is excellent. Their efforts were and are always in improving their living condition compatible to the environment. Our initiatives are diversified in many ways. Some are good, some are bad and some are ugly. Lately, with the onset of commercial revolution, we have mostly added to pollution load of the environment or developed weapons of mass destruction. Technology which used to improve machine performance has focused its attention to human efficiency. We call it productivity. We pretend to exploit it as outsourcing. Green technology got no option but to bring in it and take charge of the entire state of affairs developed by the human being kind.

Green technology targets for an appropriate, equitable and sustainable environment by interlacing all known technologies and individual involvement with environmental science to conserve and upgrade the surroundings and bringing it back to the quality available some 300 years back. Green technology could be termed as a refinement in the obtainable technology in as much as, it helps in handling pollution of all kinds in such a way that these turn out to be ecological and economically friendly.

Technology that are green are rated by their carbon footprints. A competitive and successful green technology has a low set of greenhouse gas emissions from people, product, process, event or organization. There are two ways to achieve the objective. The first which may be referred to as green acts, is usually to recycle the waste, reuse through reconditioning and other alternatives, reduce resource intake and to conserve available natural resources. The second which is definitely creating a green conditions, is to evolve systems that decrease greenhouse gas emissions hence reducing carbon footprint. These measures have verified effect on global warming reduction.

The first category of green technology is to encourage and redefine the conventional ways of keeping carbon footprints at a low level. These are recycling and its extension to water and air purification, solid waste materials treatment including sewage treatment.

Recycling defines environment by conservation at its top. Used components generally thrown as waste is recycled into new products. Composting is an age old concept of recycling green waste into manure. Recycling plastic waste into new plastic material products is most prevalent today. Recycling reduces fresh raw material consumption by utilizing middling and scraps. It reduces wastage of energy that is required to convert fresh natural material into end products It reduces air pollution as waste is now recycled instead of incineration. It reduces drinking water pollution as there can be less land filling thus reducing leachate reaching water bodies.

Waste water is purified by chemical, mechanical and biological procedures to convert it all into drinking and additional usage. Air is certainly purified both in industries along with places of human habitation in closed spaces. Industrial air pollutant such as Sulfur oxides gives back Sulfuric acid, particulates such as for example fire ash is converted into cement and bricks. Solid waste era from human habitat is normally segregated into bio-degradable and non-bio-degradable waste materials. Bio-degradable waste is composted into manure and bio-fuel. Non-bio-degradable waste is further separated into metal, glass, plastic etc. The initial three are used as intermediate raw material and recycled in to the production pipeline to get useful products. Hazardous waste materials are suitably treated to non-hazardous entity and then most of these are also recycled. Sewage treatment has acquired a state of the art technology. It is usually treated to make it free from parasites, bacteria, fungi, algae and viruses. Treated solid waste can be used as manure and the treated waste water is either utilized for irrigation or additional treated to create it suit for domestic use.

Green technology that creates and sustains green condition has focused its attention primarily in renewable energy resources. Renewable energy such as solar, wind, tidal, nuclear and geothermal have been identified as having minimum greenhouse gas emission and offers tremendous potential to replace the conventional energy suppliers such as fossil fuel and petroleum. The latter are non renewable energy resources that are major pollutants and major reasons for greenhouse gas emissions.

Green products are a category in itself as it has both the properties of reducing greenhouse gases and replacing highly polluting non-renewable energy resources. Energy cells are one example. It eliminates polluting of the environment from automobiles and it replaces hydrocarbon gas. Plastic cement manufactured from waste plastic bottles is another example. This product takes less energy for its preparation than the conventional cement produced from iron slag, lime and sand. Moreover, this plastic cement has even more permeability and hence can breathe better. Rain water can filter through surfaces prepared from it and therefore enrich the water table beneath.

These days, market is getting flooded with toxic plastic material toys which are highly injurious to the sensitive and tender toddlers. These are being replaced by toys made from recycled plastic bottles. The latest advancement in this segment is definitely fabric created from used plastic bottles material. Dress material for Cricket India members are produced from this fabric.

Green technology is definitely catching fast the computer software segment too. Now there is software which shall alarm you from wastage of energy while you are in your home or at the various other side of the globe.

There has been a lame excuse floating around that shifting to green technology requires too much analysis and development and the expense of implementation is very high. It may be appropriate for some such endeavors such as technology for geothermal energy usage. Additionally it is argued that it takes lot of period to break even. Here, people fail to compare such logic with technology that are in use and afterwards revised to green technology. An instance in case is the steam engine which saw transition to diesel engine and now almost replaced by electric engines and in near future with electromagnetic induction forces and magnetic forces. A time cycle would present that invention and commissioning of coal driven steam engine got a significantly longer maturing time than electrical engine or the future versions. All such transformations are far too profit friendly. Break-even period in addition has been quite low.

You could expect wonders in the future with the advent of nano technology. Imagine a chip grafted in your brain to displace computers which are one of the major consumers of electric energy and are generating huge electronic waste. You should start dreaming of recharging your space automobile with universally available solar energy replacing high cost, highly pollutant and weighty weight, cryogenic fuel. You may have the satisfaction of travelling in determined flying objects to several light year distant area of the universe.

Green technology is certainly marching towards a future that has a future.
