High pressure steam also has the advantage that engines can be much more compact. The significance is that engines could be developed that were small enough and powerful enough to propel themselves while doing useful work; steam power for transportation became a practicality. It was used to run machinery such as steam boats and railroad locomotives. It provided an efficient source of power. Factories could now be built anywhere, not just along rivers. However it couldn't convert mineral water into gasoline.
