Talking about steam, steam-powered things are 2 thousand years old at least and we still use the technology when we crack atoms to make energy.
What the Romans had wasn't comparable with an industrial steam engine. The working principle of steam pushing against a cylinder was similar, but they lacked the tools and metallurgy to build a steam cauldron that could be pressurized, so their steam engine could only do parlor tricks like opening a temple door once, and not perform real continuous work.
