I'm sure you could, if you really wanted to. You could drive a small turbine or windmill blade with the compressed air and couple that to an electrical generator.

The downfall would be the practicality. You would be using a compressor to produce the 'energy' needed for this process in the form of compressed air.

Any time you use an energy source that takes energy to create, you lose efficiency in the long run. Why generate power with compressed air which took electricity (or gasoline) to create? Just do it with a gas-burning electric generator or the existing electricity for the compressor.

In order to be most viable and economical, the process must use energy that doesn't require additional energy to create. In other words, it must be natural energy in the form of sun, heat, wind, gravity (hydro plants), etc.

Not in the same sense you would compress a gas for example. Various battery technologies are being made smaller and deliver the same amount of power as older and larger batteries. In this sense the size of the battery decreases for the same power could be seen as a compression.

Piezoresistive elements can be ceramic or plastic. They generate electricity when compressed.


What has to happen to the raw materials before it can be used to generate electricity?

It must be burnt and then compressed to get all of the useful energy out. Then the energy let out is measured in joules and used for electricity.


What is the difference between compressed air tools and battery tools?

In a compressed air tool the driving force is air pressure. While in battery tools the electricity from the battery is converted to electromagnetic force to drive it.


Is the pressure of the clouds being compressed and heated which cause the lightning?

No. It is the buildup of static electricity in the clouds, caused by the motion of the air within the clouds.


Storage technologies for storing energy?

It depends on what energy you are referring to. If it is electrical then there are few things that can store utility level electricity in its form. Typically utility level electricity would be converted into mechanical energy or converted into chemical energy. For example a wind power generation facility would store energy by creating compressed air and storing the compressed air in an abandoned salt mine. When the wind is not blowing strongly to produce electricity the compressed air is released to spin another power generation turbine. A chemical power storage solution would involve using the electricity created to make hydrogen. The hydrogen could be stored and used later for power generation. http://www.energybulletin.net/node/11252

What energy is used to keep a machine moving?

When it come to machine, it can be run on various energy source. Industrial machine usually run on electricity but some would run on compressed air and use electricity for fine control of compressed air. Some heavy industrial machine like driller might run on gasoline. Some pump might as well designed to run on steam pressure and compressed air. I believe there is no limit to what energy source it could be use to power, just what energy source would be convenience and fit to the task.
