“Perhaps you should build them for Boeing.“

I didn’t build them. I calculated the requirements, drew the P&IDs and specified the equipment, piping and instrumentation. I’m now retired, however.

“Odd that it doesn’t cool the plastic inside windows on the plane that quickly. And there’s not even whole bunch of machinery between the actual window and that little plastic inside window.”

Nothing odd about it. It’s quite simple. Two or more thermal plastic/glass panes with almost full vacuum in between constitutes an aircraft window. It’s heat/cold insulation.

That's not true. The outer and middle windows do not have a vacuum in the space between them. Ever notice the little hole at the bottom of the middle window? The pressure in the space between the two windows is the same as the cabin pressure. (And of course there's no vacuum between the middle and inner plastic window you can rest your head against. Those aren't air tight.)
