Re: Solar powered cooling
Zeolite is a crystal and is used in removing ammonia in fresh and marine aquariums. I used to use it but now I use a protein skimmer to remove wastes from the saltwater before it causes algal blooms.
You are right that after absorbing water it can be heated to release steam and this steam can be used for various uses but you need 'heat' besides the high heat from hot temperate zones or use heat from the engine exhaust...
Heating and refrigeration:
Zeolites can be used as solar thermal collectors and for adsorption refrigeration. In these applications, their high heat of adsorption and ability to hydrate and dehydrate while maintaining structural stability is exploited. This hygroscopic property coupled with an inherent exothermic (energy releasing) reaction when transitioning from a dehydrated to a hydrated form make natural zeolites useful in harvesting waste heat and solar heat energy.
Here is one you might want to read up on...
