I am suppose that heat can be captured or recycled back into inside air, not
by actually blowing vent air inside house but by sending it throu a coil of
pipes with heatsinks that would take heat from the hot air passing through
it and radiate it back into room. I have seen a similar technique using for
allowing air ventalation from inside to outside by exchanging the heat
energy from from to exhaust by conduction through metal.

Usually in winter, indoor humidity levels get pretty low,

Storm windows can greatly alleviate humidity loss.

I make mine on a frame of 5/8 inch unfinished bolding stock,
mitred, glued, and stapled at the corners. Then 3 mil acetate sheet is
stretched over the frame and stapled down. Finally, foam weather
stripping
is attached around the frame's perimeter, to make a tight seal against
the
window casing.
