AIR DRIVEN ENGINE ABSTRACT: The Air Driven Engine is an eco-friendly engine which operates with compressed air. An Air Driven Engine uses the expansion of compressed air to drive the pistons of an engine An Air Driven Engine is a pneumatic actuator that creates useful work by expanding compressed air. There is no mixing of fuel with air as there is no combustion. An Air Driven Engine makes use of Compressed Air Technology for its operation The Compressed Air Technology

Indoor Air Quality INDOOR AIR QUALITY: INTRODUCTION The connection between the use of a building either as a workplace or as a dwelling and the appearance‚ in certain cases‚ of discomfort and symptoms that may be the very definition of an illness is a fact that can no longer be disputed. The main culprit is contamination of various kinds within the building‚ and this contamination is usually referred to as "poor quality of indoor air". The adverse effects due to poor air quality in closed spaces

Air Conditioner Report The use of concrete blocks in buildings construction decreased natural ventilations in the structures. The situation was worsened by house designs in urban areas where there were small spaces left for air waves. This lack of ventilation and variations n weather patterns necessitated a gadget that would keep rooms at suitable temperatures for human comfort. The air conditioner has a mechanism that absorbs humidity from the air to create a cooling effect inside buildings when

Effects of Air pollution: There are different kinds of negative and harmful effects of air pollution. The effects of air pollution are described below. 1. Global warming: Air pollution causes global warming in a great scale. With increased temperatures world wide‚ increase in sea levels and melting of ice from colder regions and icebergs‚ displacement and loss of habitat have already signaled an impending disaster if actions for preservation and normalization aren’t undertaken soon. 2.
