"Steam locomotives clattering along railway tracks. Paddle steamers churning
down the Murray. Dreadnought battleships powered by steam engines.
Many of us think the age of steam has ended. But while the steam engine has
been superseded by internal combustion engines and now electric motors, the
modern world still relies on steam. Almost all thermal power plants, from coal
to nuclear, must have steam to function. (Gas plants usually do not).
But why? It’s because of something we discovered millennia ago. In the first
century CE, the ancient Greeks invented the aeolipile – a steam turbine. Heat
turned water into steam, and steam has a very useful property: it’s an
easy-to-make gas that can push.
This simple fact means that even as the dream of fusion power creeps closer, we
will still be in the Steam Age. The first commercial fusion plant will rely on
cutting-edge technology able to contain plasma far hotter than the sun’s core –
but it will still be wedded to a humble steam turbine converting heat to
movement to electricity."
