The Stirling Engine is the second tier Buildcraft Engine, it uses Coal and similar items as a fuel source and runs faster than a redstone engine. Stirling Engines are considered the more powerful alternative to Redstone Engines, and the safer alternative to Combustion Engines; so long as a Stirling Engine has somewhere to send all of its power, it will not overheat and explode. However, if a machine is using less power than the Stirling Engine produces, or else the Engine is not connected to anything while activated, it can potentially overheat and explode.
To power a Stirling Engine, the player simply places a fuel source in the Engine's GUI -- coal for example -- and start it with a Redstone signal. A Lever is the easiest and cheapest method, requiring no actual Redstone to function, if placed adjacent to the Engine.
The Stirling engine requires three cobblestone, two stone gears, one piston and one glass block to craft. It is more effective than a redstone engine in terms of energy, but it carries the risk of exploding and needs to be refilled.
Types of fuel accepted by the Stirling Engine:Edit
You can use the following types of fuel to power the Stirling engine:
- Lava bucket
- Wooden Plank
The most efficient fuel source to use for the engine would be charcoal as it has the same burning time as coal and is a renewable resource. By using forestry (not in latest version) and setting up automated tree farms, you can have a steady supply of charcoal to power these engines.
