Hybrid heating and cooling for water and energy sustainability



Innovations in energy and water sustainability are important to address Global Challenges. For instance, direct solar desalination exhibits considerable potential for alleviating the global freshwater crisis. In this talk, I will first go through our recent research efforts to develop inexpensive solar-driven evaporation architectures. Its potential applications for zero-liquid-discharge water treatment using evaporation ponds will also be discussed. However, if the evaporated moisture cannot be collected, they can only be considered as a “pollution” to the atmosphere. As the entropy sink, the cold source is an integral part of a complete thermodynamic cycle in all heat-producing technologies. The unique challenge is to obtain coldness from renewable and sustainable sources. In the second part of this talk, I will discuss our recent efforts on radiative cooling in water and energy sustainability. In particular, the potential to recycle atmospheric water using passive cooling technology will be discussed.
