A solar closet is generally a south facing water filled Drumwall
disposed in a super insulated box.

Is there any exemple of a similar solar heat storage that runs
from south to north of a building ceiling (like a duct) ? I
guess one would use a Cansolair-like solar heater to recharge
the "storage duct" during the day and discharge it with a fan
that pushes the hot air throught some louvres at night.

For starters, check out Nathan Hurst's nice Barra system Wikipedia article.

Good article. I like the idea of using 4" PVC pipes filled with
water to store heat. Pipes could be the way to do for already
existing houses where storing space is a problem. Suspending the
pipes between two solid beams that goes from one end of the
ceilling to the other seems logical in that case. If the pipes
are stacked in a well insulated box the heat could be used only
when needed instead of radiating all day long.
