small energy

 Simple effecient ways to convert compressed air to electricity.
Looking for ideas and info about existing technology.How much
electricity can be obtained from X volume @ Y psi in KWH?

Compressed air is a VERY poor way to store energy. You get lots of
losses.

I'm looking for the same thing but with a twist.

you can change the air pressure over to fluid pressure which will do work, a
lot more work than air alone with little losses.

If you have got an old well tank fill it three fourth with water and
pressure it with air, now the water coming out the bottom of the tank is
fluid pressure. I understand as soon as the water flow starts the pressure
drops so just have a much bigger air tank than the water tank. To keep up
the water flow you much have two or more of these tanks so the fluid
pressure does'nt stop while the tank is being filled again (automatic
electric valves)

the alternator in a drum thing might work like this


whats for supper grandpa?

That's an interesting concept. Just how much more energy do
you get from fluid pressure than you get from air pressure?
If you use the water to compress air, do you get more energy
out than you put in? :)

Seriously, there isn't anything about an air engine that
requires it to be more inefficient than a water turbine.
It's just that the only air turbines most people are
familiar with, air tools, aren't built to be efficient.
They are built to be lightweight and powerful. It's no
surprise that they aren't very efficient.

I am saying using the air pressure to push a liquid out of a tank.  The
fluid pressure will be the same as the air pressure above the liquid in the
tank.

fluid turbines have more power per pressure release ratio. something to do
with moving masss. The air pressure will be easier to obtain thru a
compressure but multiple tanks will have to be used
