How do espresso machines work?

ok. I see you have very substandard answers so far, lol...
An espresso machine is a fine instrument, tuned to perfection.
Three things are paramount in the making of espresso coffee...
1) Pressure. This is what an espresso machine does that your regular coffee maker does not. The pressure forces the flavor from the coffee and through the basket, getting much more flavor out of the ground coffee bean.
2) Temperature. Another thing your regular coffee maker cannot do is heat up the water to the degree that an espresso machine does, a perfect temperature that was studied for years and years by the founder of espresso machines, Doctor illy.
3) The bean. Espresso machine beans should be superior, and the bean is ground much finer than the coffee that you may pick up at your local store.
The machine heats up the stored water and forces it through the ground coffee beans. That is how they work in a nutshell.
