WaterProducer-Greenhouse™

Agri-business and water bottling enterprise market

• 200,000 L/day

• Lifetimes: equipment ~ 10 years, structure ~ 20 years

Progress made (IP)

• Viability Study (supported by Canadian International Development Agency*) successfully completed for a proposed installation on the island of Grand Turk, Turks and Caicos Islands
• WaterProducer Greenhouse™ computer model
• Financial model for a water + food producing business with the Greenhouse system at its core

Next steps

• Proof of concept prototype
• Functional prototype—WaterProducer™ at tropical carbonate island site using saline groundwater from 250 m depth as natural coolant
• Pre-production prototype—Grand Turk site using natural coolant from 500 m depth of carbonate island 
• Production—turn-key installations at multitude of sites along arid tropical coastlines. Natural coolant access either from deep wells drilled in carbonate islands or pipeline to thermocline depth in ocean (for islands with bedrock of volcanic origin)

Natural coolant from saline groundwater is pumped to the surface. Energy to power the exhaust fans and lift the coolant can be from wind generators to provide a sustainable and environmentally-friendly water-producing system.
