There’s that.

And there’s the kid who pointed out that the Emperor was naked.

(If you’ll note, questions were asked. Not to do so, when they exist, would make one a cheerleader.)

Guys,

“It is not the critic who counts………”

if you’re not familiar with Theodore Roosevelt’s quote, do look it up.

As Ricardo have validated this as worthy of further investigation, I feel shooting it down in such a dismissive manner quite sad, unless of course you have a better solution, or indeed any solution?

So, what is the “liquid heat exchange fluid”, and how is it prevented from going out the tailpipe with the expanded gas?

Is it just water? If so, I guess having it go out the tailpipe wouldn’t be a problem — except your system might ice up easily. If it’s some other, more exotic fluid, then you’re going to have to take some kind of efficiency hit to retain it.

And I can’t imagine this is terribly efficient in the first place. You will most likely lose quite a substantial portion of the original energy source (I’d guess grid power) in making the cryo-air.

This in contrast to EVs, which use that grid power with 80%+ efficiency, including going to the batteries and back. And can you pack enough cryo-air and exchange fluid into a car to compete with even current battery capacities, in terms of volume and weight? And future anticipated capacities?
