The power of atmospheric pressure, the power behind the Newcomen Steam Engine of 1712

Описание к видео The power of atmospheric pressure, the power behind the Newcomen Steam Engine of 1712

We don't think much of the atmospheric pressure that is around us at all times but its power is incredible. In 1712, Thomas Newcomen changed the world by displacing air with steam in a cylinder and then cooling the steam allowing atmospheric pressure to push a piston into the cylinder. It's much more powerful than you might think, and was put to work replacing teams of horses and hundreds of men. It was the first significant way of turning heat into work. This video experiment demonstrates how powerful that atmospheric pressure can be.
