TRL3 Experimental Proof of Concept
Application
Water scarcity is a pressing global concern and the availability of clean water and sanitation is one of the United Nations’ 17 sustainable development goals. Reports show that over half of our planet’s population suffers from water shortages for at least one month a year. Air-water-generation is a compelling approach because water vapor is intrinsically renewable, local and potable. Passive methods are of immense value because they do not require power to drive water generation. Currently, maximum yields for passive devices are unacceptably low, ranging up to 0.6L/m2 a day.
Our Innovation
Technology
The research group has proposed a new system design that surpasses previously projected theoretical yields, by separating the radiative emitter and the dew collector. The proof-of-concept validated the model when tested under lab conditions.
The operating costs of such a device approach zero, limited to the cleaning of parts and surfaces. There are no moving parts in the final design.
Opportunity
There is a constant need for access to potable, low-cost and carbonless water. Technologies that can do so at local scale will be of perennial interest. Such a technology may be combined with other systems (e.g. local gardens) to provide a source of low-cost, clean water.
