I loved the video, but as an energy engineer, I can't help to correct you on one issue: most gas power plants are NOT boilers.<br>Instead, in gas turbines it is the hot, compressed exhaust gas that makes the blades spin. <br>At the exit of the turbine, in SOME plants, known as combined cycle plants, they have boilers (steam generators, to be precise). This raises the plant's efficiency by a great deal, but comes at the cost of not being able to adjust the power output and get the plant working from zero to full power all that quickly.
