The energy needed for phase change for supercritical CO2 is substantially lower than steam.
There’s more wiggle room. My understanding is that similar to heat pumps, they can build systems with different optimal temperatures, and even daisy chain them together. They’ll never make a perpetual motion machine, but they can waste less energy.







Okay, but have you ever kissed the side of a woman’s half-shaved head or scuffed your face on it during hugs?
It’s like easily 100% more skin to kiss when the hair is short. Awkward drive-by forehead kisses are all but eliminated as she doesn’t have time to react to try to give you real kisses and then you miss and kiss her nose. Just a big ol’ target right on the side of her head that you can easily hit from the front or back. So much easier to seem suave.
And the hugs! You get more skin to skin contact without all that hair keeping your faces apart. It’s more hug per hug.
