Steam implies water! What if we used some OTHER phase-change working fluid? :D
||(No idea what, though. my question is implied with a playful tone and is at least 50% facetious; any actual discussion that might result would be little more than a pleasant coincidence)||
You want to see weird water look up super critical boilers. That stuff was nasty. A regular steam leak will set things on fire. That stuff would explode a broom. We looked for the leaks with straw brooms. You can't see steam in normal conditions. Only its effects.
Blech, I've heard stories in my industrial automation days of people being clipped by invisible high pressure steam leaks. No frickin thank you, regular stovetop steam jacks me up frequently enough.
Not quite invisible but you could also splash and wade into a pool of strong acid thinking it was water, during what first seemed like a somewhat routine FUBAR maintenance situation...filling your boots etc.
The only truly new method of power generation we've made in the last 100 years has been photovoltaic cells. Everything else is just finding new ways to make turbines spin.
I've actually seen this same meme used in the opposite way where they did discover a new way but I don't remember enough information to find it. And I don't think it was talking about solar.
