I had a great email from a student recently who was doing a science fair project with steam turbines. He wanted to know how he could improve a model turbine he'd built to get more energy out of it.

The first thing to note is that steam can be incredibly dangerous (for the reasons outlined in the box up above): it contains a huge amount of energy that will burn you very badly if you touch it. So do be very careful if you're doing experiments with steam turbines and steam engines. However, for exactly the same reason, steam is incredibly useful: if we harness the energy it contains, we can do extraordinary things—like driving ships and locomotives or generating electricity. The Industrial Revolution that powered the world through the 18th and 19th centuries largely ran on the power of boiling water. That's an amazing thought!
