Evolution of Air Power The Beginning The use of the expression ‘air power’ was first recorded in H.G. Wells’ novel ‘The War in the Air’ in 1908.1 However‚ according to Professor Tony Mason the official birthday of air power has arbitrarily been selected as 1893‚ when a Major Fullerton of the British Army had presented a paper to a meeting of army engineers in Chicago in which he prophesied that the impact of aeronautics foreshadowed ‘as great a revolution in the art of war as the discovery of

http://www.blankees.com/house/plants/air_cleaners.htm Houseplants can be very beneficial in our lives. They purify and renew our stale indoor air by filtering out toxins‚ pollutants and the carbon dioxide we exhale - replacing them with life sustaining oxygen! Although it should be safe to presume that all plants are capable of removing toxins from our air‚ research by NASA showed that some house plants are more efficient in filtering out toxins than others.

Air Powered Car A compressed air car is a car that uses a motor powered by compressed air. The car can be powered solely by air‚ or combined (as in a hybrid electric vehicle) with gasoline‚ diesel‚ ethanol‚ or an electric plant with regenerative braking. History Compressed air has been used since the 19th century to power mine locomotives and trams in cities such as Paris (via a central‚ city-level‚ compressed air energy distribution system)‚ and was previously the basis of naval torpedo propulsion

Air Pollution "Air pollution is a serious problem in many of the worlds large cities. Heavy concentrations of air pollutants‚ which are often in the form of smog‚ settle over a city‚ creating a health hazard for its people. Air pollution occurs when wastes dirty the air. People produce most of the wastes that cause air pollution. Such wastes are usually in the form of gases. These substances result chiefly from burning fuel to power motor vehicles and to heat buildings. Industrial processes

Air Pollution: Causes and Effects It keeps us alive but at the same time‚ it can also be harmful. We breathe air everyday. Air provides us with oxygen that is essential for living. Nitrogen‚ water vapor‚ and inert gases comprise air along with oxygen. Emission of substances that contaminate air results to pollution. Air pollution is both natural and human-based. Natural air pollution is caused by phenomenon such as volcanic eruption‚ wind erosion‚ decomposition and radioactive

Air pollution my speech Air pollution is the introduction of chemicals‚ particulate matter‚ or biological materials that cause harm or discomfort to humans or other living organisms‚ or cause damage to the natural environment or built environment‚ into the atmosphere. Air pollution has been a problem throughout history. Even in Ancient Rome people complained about smoke put into the atmosphere. Every day‚ the average person inhales about 20‚000 liters of air.
