The single piston engine worked really well. It enabled me to construct my experiment with ease. I didn't need the light bulb to do my experiment, but it didn't work anyway. I even tried it with batteries and it still didn't work. The piston engine is so well designed that I will definately shop at StirlingKits again, and as soon as possible. The delivery time was perfect, and the box arrived in perfect condition.
