This page lists some of the common sources of air pressure to power a pneumatic, and the advantages and disadvantages of each:

==Gases==

'''Air'''

Advantages:
* It's price (completely free of course)
* Global availability.

Disadvantages:
* Limited performance approaching the sound barrier.

Performance of air is moderate. It is very uncommon for a air powered launcher to exceed the sound barrier, but not completely impossible. Most gases are compared against air as a benchmark
Sources: If you want to use air, you'll either need a [[compressor]], [[Hand pump|hand/foot pump]] or a [[gas bottle|High Pressure Air (HPA) tank]]

'''Helium'''

Advantages:
* Exceptional performance
* High speed of sound and particle speed

Disadvantages:
* Costly
* Will leak faster than any other gas
* Helium regulators typically limited to 200 psi.

Performance is second only to Hydrogen.
Sources: Unless you have an on-site extraction plant, the only option is [[gas bottle]]s

'''Nitrogen'''

Advantages:
* Performance slightly better than air.
* Option for high pressures.

Disadvantages:
* Costly

Nitrogen is slightly more powerful than air for a given pressure, but nitrogen regulators are capable of very high pressures.
Sources: Unless you have an on-site extraction plant, the only option is [[gas bottle]]s

'''Hydrogen'''

Advantages:
* Highest performance gas.

Disadvantages:
* Costly.
* Potential explosive risk.
* Will leak fast.

Hydrogen is the most powerful gas that can be used in a pneumatic, but it has numerous risks associated with it.
Sources: Unless you have an on-site extraction plant, the only option is [[gas bottle]]s

'''Carbon Dioxide'''

Advantages:
* Reasonably cheap.
* High pressure.
* Highest gas volume to bottle volume ratio

Disadvantages:
* Low power
* Very heavy cooling on decompression (can cause problems with PVC launchers)

CO2 is a very common bottled gas, but it's power is limited by it's high density.
Sources: [[Gas bottle]]s, [[CO2 cartridges|Gas bulbs]]

'''Propane'''

Advantages:
* Reasonably cheap.
* High gas volume to bottle volume ratio
* Easily available.

Disadvantages:
* Low power
* Low pressure
* Possible (if unlikely) fire risk

[[Propane]] is better known as a [[combustion cannon]] power source, but some pneumatics have used it as a gas. It's performance is low, because of it's high density and low pressures, but it is cheap and easily found.
Sources: [[Gas bottle]]s, either in large bulk tanks of several kilograms, or in small tanks of 0.5 - 1 lb.
