With more than 1.9 billion people living in water scarce areas, the need for a reliable, sustainable source of clean water is imperative. CSIRO scientists have developed a device that can harvest potable water from straight out of the ambient air, using metal-organic frameworks (MOFs).
This technology stands out as it can operate in the majority of humid conditions found on the globe. Optimal operational range starts at 30 per cent Relative Humidity upwards, with more limited performance down at the very dry 15 to 20 per cent RH. It has been designed to maximise energy efficiency per litre of water produced. Its operational versatility means that it can be scaled to suit the required need from small litre quantities to larger volumes.
We have a patent for the material production at the heart of the device, which is licensed to a local Australian manufacturer. The AWG prototype is also protected through a provisional patent.
We are exploring options to establish a spin out company to produce and sell devices based on this technology. Interested investors are encouraged to contact the commercialisation team to explore potential investment.
