Hilsch Tube for Cabin Temp control...

Has anyone ever attempted to install a Hilsch Tube (Vortex Tube) in an
aircraft for environmental controls?

I built one of them in High school as a science fair project. it
worked, but was noisy as hell. Usually, vortex tubes are used for spot
cooling, due to their low efficiency. One big enough to cool a typical
aircraft cabin would be quite large, and as I said, NOISY!

We're talking about using exhaust pressure energy that would be heading
out the tail pipe anyways, right?

Eh... its all 'armchair engineering', I know- just fun to think about.
I can definitely see how such a system might be useful (internal
climate control, wing anti-ice) if the engineering hurdles could be
worked out (noise, high enough input flow, weight (possibly))
