Upper water reservoir and nuclear reactor: what they have in common

1. Step 1. Upper water reservoir — is part of — Carbide lamp. Water drips onto the carbide.
2. Step 2. Carbide lamp — has part — Valve. It regulates the water supply.
3. Step 3. Valve — is part of — Watt steam engine. A slide valve distributes the steam.
4. Step 4. Watt steam engine — evolved into — Steam turbine. The turbine replaced piston engines in large installations.
5. Step 5. Steam turbine — is part of — Nuclear power plant. Steam turns the turbines — as at a thermal station.
6. Step 6. Nuclear power plant — has part — Nuclear reactor. The reactor heats the coolant.
