The Redstone Engine is the least powerful engine in the Buildcraft mod. It is crafted using 2 wooden gears, 1 piston,
1 glass, and 3 wooden planks.
The most common use of the Redstone Engine is to pump items out of containers. Others are for powering pumps, pulling liquids out of tanks, and generating very little power. They dont need Coal or wood, or another fuel, is only put a redstone signal near.
Remember that it is an engine but is the only one that doesn't explode.
