WaterProducer™ water-from-air system

  • Water-bottling; District water utility market
  • 50,000–200,000 L/day (10,000–40,000 people/day)
  • Lifetimes: equipment ~ 10 years, structure ~ 20 years

Progress made (IP)
  • Computer model (software)
Next steps
  • Proof of concept prototype—validate concept of chilled liquid cooling for dehumidification of air for drinking water supply
  • Functional prototype
  • Pre-production prototype
  • Production models (200–5000 L/day; fitted into shipping containers) or turn-key installations (up to 200,000 L/day); enclosed in polytube style greenhouse structures)
