3. You can compress a fluid? That's possible?

It was my understanding that liquids are considered incompressible. That's why hydraulic systems can work so well; the fluid doesn't compress but transmits power, rather than absorbing it through compression as a gas would.

The article says "The energy is stored in pressurized hydraulic fluid..." which is a well-known and widely used method. However, it says later that "braking pressure is used to power pumps that compress hydraulic fluid."

Any clarifications?
