How does a steam engine work
A steam engine is a heat engine that converts heat energy from burning fuel into mechanical work. It is a simple and robust type of engine that was widely used in the 18th and 19th centuries to power trains, boats, factories, and other machinery.

Here are the basic steps of how a steam engine works:

1. Fuel is burned to create heat, which is used to boil water in a boiler.
2. The steam produced from the boiling water is piped into a cylinder, which contains a piston. The steam pushes the piston, causing it to move.
3. The movement of the piston is transferred to a connecting rod, which in turn rotates a crankshaft.
4. The crankshaft then drives the machinery or vehicle it is connected to.

The steam engine uses a clever mechanism to convert the linear motion of the piston into rotary motion that drives the machinery. This is done using a linkage called a crosshead that is attached to the piston rod and connects it to the crankshaft.

The steam engine also has a valve mechanism that controls the flow of steam into and out of the cylinder. This valve is typically operated by an eccentric mechanism that is driven by the crankshaft.

Overall, the steam engine is a simple but powerful device that revolutionized the way we live and work. While it has been largely replaced by more advanced technologies, it remains an important part of our history and heritage.
Suppose we used a small fusion reactor to boil the water. Would this be the most efficient method for movement with fusion energy?
