Thread: how to generate electricity using "Air Compressing"

i read a book that was talking about generating electricity using ocean waves and seas ( turbines ), after that the book talk about generating electricity using "Air Compressions", but with no any details about that

i searched and found no thing about that, can anyone help

How we generate electricity Compressing Air
And, is there any relation between that and Oceans ( turbines )

Waiting for answers ..

The compressed air can generate electricity by spinning a turbine or by use of pistons and cylinders.
This has been proposed as a way of storing power generated by wind or solar power.

Excellent Resources and information
Thanks .

But, an external _and may be internal_ question,

i saw in the second link you posted that the writer used Ideal Gas Equation to describe how that engine works, Why he didn't use the Corrected gas equation ?


in another way, in the real life, when we're going to design a such engine or any another device depends on Ideal gas equation, we'll use the normal or corrected equation ?
