How about adding a thin perspex flap across each shelf

what is Perspex?

Shelves on rollers that slide left and right as you look at the fridge

with the lid up might halve the capacity...

That might work

That might work

I think the main heat gain with the door open is condensation on cold
fridge contents from room air. Baskets that lift out with poly film
liners would also work, and avoid collecting much condensation on
their contents when they are lifted out.

A type of plexiglass-type substance:

Didn't know such a thing existed.
Do you have a link to one?

A quick google search found me this example...

Very interesting!

Thanks!

Our 35 F chest-refrigerator with 50% RH has14 grains of water-vapor in
each pound of room air

I'm not sure what you mean by that. It seems to me that the moisture in
the room air is more important than the moisture inside the fridge when
the fridge door is closed.

But Nick's rooftop solar still bakes his LiCl desiccant liquid to
50% concentration. This puts his room air, which is in vapor-pressure
equilibrium with it, at a vapor pressure of 0.109 "Hg, with a RH of
7.5% and its dewpoint is 18.2F

That's a completely different application (cooling and dehumidifying
a house), and the vapor pressure of the room air would be higher than
the vapor pressure in the still.
