Steam locomotive - Wikipedia

The intense heat causes water in the boiler to turn into steam, which is piped into the cylinders (24). Valves (25) cause the steam to oscillate the pistons (23) back and forth. The piston rod (22), connecting rod (21) and coupling rod (19) transmit the movement to bearings on the wheels, converting the oscillation to rotation, which moves the locomotive as shown in this animation

Biogas - Wikipedia

Biogas is the mixture of gases produced by the breakdown of organic matter in the absence of oxygen (anaerobically), primarily consisting of methane and carbon dioxide. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste.Biogas is a renewable energy source.. Biogas is produced by anaerobic digestion
