Found this on another “social” network - and thought I’d share with you, as I think the principle is pretty intriguing.
The article itself reads a bit sloppy - but explains what’s going on quite well imo.
On the sun-drenched Mediterranean island of Sardinia, in the industrial zone of Ottana, rises a colossal, gleaming white elliptical bladder structure that looks like an indoor sports stadium or a terrestrial space habitat. Instead of
tldr :
like steam engine but replace water with CO2
(and more efficient if no gas is lost)
liquid at (20 to 30)⁰C, ~65 atm
gas at (-40 to +40)⁰C at least and 1 atm
(it needs a huge place for storage of course)the trick is that in high energy state carbon dioxide is liquid held under pressure instead of high pressure gas, like it works with compressed air energy storage, this makes it much more efficient
the article is wrong tho. after compression carbon dioxide doesn’t stay at supercritical state, it gets cooled into liquid. text is slop and so are images. there’s more errors
So what’s the resulting pressure in the liquid, approx?
vapor pressure of liquid carbon dioxide at whatever temperature storage tanks happen to be. wiki tells me it’s 60 atm at 22C and 40 atm at 6C, so not that much in grand scheme of things
Awesome concept, and really cool that it’s actually been built!
reads a bit sloppy
I caved in about half way, at that point it was just churning out more words.
The weird golf ball places with fancy computers in them use this design to reflect signal attacks.
I use this design to make Dorito balls. The trick is to glue with cheese. It works really well when capturing people who would dare to eat a Dorito ball.
So does cool ranch or original nacho cheese work better?
Mix both together & you can catch shiny rares at Walmart. Just be sure to bring ‘really large pokëballs’.
