:>it your "wall" is thin (like a double paned window) you wouldn't gain :>anything filling it with bubbles. : :Can you define "anything"? :-) my premise is that if the gap is thin enough then convection is not a big issue. So the effect of the bubbles is merely to ad an (admittedly small) conduction path. : :>If you had a thicker wall you might gain something :>assuming you could get the bubbles to stay put. I was imagining that you fill the chamber with bubbles and they somehow just stay there. Or are they continuously moving up and breaking with the soapy water draining back to be recycled.
