This is good news: we can use this technology to build watertraps to store water in our sietches after the world turns into a giant desert.


I'm not sure the current tech scales terribly well. but hopefully they can expand on it to develop something that does scale.


The technology is based on the design of an emulsion from nanoparticles, wax and pollens derived from plants. It is then sprayed onto a substrate to produce a texture surface, mimicking superhydrophobic surface like a lotus leaves. The plant nanoparticle is hydrophilic, and will nucleate tiny water droplets. We can harvest 5L of water per square meter of surface per hr. Thus, the process is scalable. You can read our research in Nature Water, (2023) 1 (7), 587-601 and Angew. Chem. Int. Ed. (2022), e202115238 (1 of 13) https://doi.org/10.1002/ange.202115238.




Oh good. I expected this to be another dehumidifier attempt.
