Compressed air is air that is pressurised to greater than atmospheric pressure. It is exactly the same as the air that you breathe only it has been forced to a smaller volume and kept under pressure. Air is made up of 78% nitrogen, 20-21% oxygen and around 1-2% of other gases as well as water vapour. When compressed, the air is still made up of the same mixture of gases, however, it will have been forced into a smaller space, bringing the molecules closer together.
Compressed air can be stored at a high pressure and is a fantastic medium for transmitting energy. Compressed air is a popular energy source as it is safer and easier than alternative options like steam and batteries. Steam can be dangerous as it gets extremely hot whereas batteries can run out of charge, making both options unfavorable.
Compressed air is safe to use, easy to store and has many versatile uses.
