Just don't forget that silica gel is a relatively excellent material
for thermal insulation.

Silica Gel is a popular dessicant mainly because it doesn't matter
if you flip it over to turn it upside down.

In stationary applications there are a large selection of salts,
including almost any chloride you have heard about, which are very
volume efficient compared to silicagel *provided* the beaker/glass/bucket
you put them in doesn't get tipped over.
