A 17th century well running without electricity

At the end of the 17th century, the famous inventor, physicist and builder Thomas Savery lived in England. Severi earned his bread by being a hired manager at one of the coal mines. And since rain in 17th century England will surprise no one, the mine where our inventor worked was often filled with water.

The idle mine caused losses, and in order to solve the flooding problem, Severi invented a pump that can pump water without using electricity. It is so simple that it can be assembled at a summer cottage. Here is its diagram, and below are my explanations.

To raise water from a well or well, we will use a simplified scheme. It is based on the property of water: when the vapor pressure in a closed vessel decreases, it sucks up the water.

Take a metal barrel and a hose. We connect one end of the hose to the barrel through the fitting, and lower the other end into the well. Pour 3-4 liters of water into the barrel and start heating it. Gradually, the boiling water will force all the air out of the barrel into the well (or well).

And as soon as we put out the fire, the steam pressure will weaken, and the water through the hose will go up by itself, into our barrel.

You say: is it really possible to burn a fire every time to raise the water?
Not! You can paint the barrel black, and in the summer the sun will do its job - the water will be pumped into the barrel every evening by itself.

Now in Foggy Albion, the invention of Thomas Severi is no longer used. The most that can be found are containers for collecting rainwater from the roof and a dispensing hose. But Thomas Severi, in fact, invented the world's first steam engine.
