| − | == Efficiency ==
| |
| − | The Stirling Engine has an efficiency curve that is dependent on three factors:
| |
| − | * Environment
| |
| − | * Working Gas
| |
| − | * Input to Output efficiency
| |
| − | The best a Stirling Engine can provide in power is 15% efficiency of the input heat, whereas a [[Kit (Gas Fuel Generator)|Gas Fuel Generator]] has a much higher efficiency ratio per Mol of fuel.
| |
| − |
| |
| − | == Environment ==
| |
| − | The Stirling engine itself is best placed outdoors in a 13-25 Celcius environment to provide the highest efficiency. The only planets that cannot effectively use it are: Venus, Moon and Mimas

| |
| − | * Moon (Vacuum): 0%
| |
| − | * [[Venus]]: 12% efficiency @ 463 Celcius
| |
| − | * Vulcan (Night): 91% efficiency @ 126 Celcius
| |
| − | * Mars: 100%
| |
| − | * Loulan: 100%

| − | === Indoors ===
| |
| − | Keeping the Stirling engine indoors to cool it down to maximum efficiency is debatable if not impossible, since the exposed working gas canister heats the room up, thus it has to be heavily cooled. The power gained from indoor cooling is significantly less than the possible power gained with a single indoor-cooled [[Kit (Gas Fuel Generator)|Gas Fuel Generator]].
| |

| |
| − | A single frame of 100kPa (330mol oxygen @ 20 celcius) will rise by 1.5 Celcius every second with 1500 Celcius gas, assuming that you are exporting from a furnace to the Stirling Engine.

| |
| − | == Working Gas ==
| |
| − | The working gas is a canister of gas that must be provided to the machine before it can be used. The gas itself is not lost, only used as a heat transfer gas.
| |
| − | When filling it, 60 mols of gas in the canister is needed, which is usually around 2.4MPa when it is pressurized at room temperature.
| |
| − |
| |
| − | '''''If the canister's pressure ever reaches 11 MPa, the machine will instantly explode.'''''
| |

| |
| − | Here are the efficiencies of several gasses:
| |
| − | * Pollutants: 5%
| |
| − | * Carbon Dioxide: 8%
| |
| − | * Oxygen: 12%
| |
| − | * Nitrogen: 12%
| |
| − | * Nitrous Oxide: 12%
| |
| − | * Hydrogen: 15% (Best)
