Tropical Small Islands

The WaterProducer-Greenhouse™ is a niche technology suited for tropical small islands having these characteristics:

Tropical, humid climate
Natural coolant (saline groundwater with reverse geothermal gradient)
Coastline within 1 km of the 200 m ocean depth contour

Carbonate Islands with Natural Coolant Resources

This technical bulletin is a reconnaissance of carbonate small island sites in the humid tropics expected to have a natural coolant resource. The reverse geothermal gradient in saline groundwater could be tapped, by drilled wells (250–500 m deep), in a sustainable process, by Canadian Dew Technologies Inc.'s WaterProducer™ system for drinking water production.
