It produces 500 litres of water in 24 hours. It needs input power of 8.8KW and consumes 0.4kwH per litre of water produced.
It sells many different types of water from air harvesters, ranging from domestic use to that of a village!
The "Villager" produces 1000 litres per day (264 gallons) and the "Irrigator" an impressive 5000 litres (1321 gallons). At an estimated AUS 3c cents per litre this is still costly if using a diesel generator. But with wind or solar...
