IBM’s New Sunflower-Shaped Solar Concentrators Produce Energy AND Fresh Water!:

IBM’s New Sunflower-Shaped Solar Concentrators Produce Energy AND Fresh Water!:

The concentrators use a direct hot-water cooling design that IBM already uses in its high-performance computers and supercomputers. However, with a bit of customization, the HCPVT system can also provide drinkable water and air conditioning from the hot water output produced. The team notes: “For example, salt water can pass through a porous membrane distillation system, where it is vaporized and desalinated . Such a system could provide 30–40 liters of drinkable water per square meter of receiver area per day, while still generating electricity with a more than 25 percent yield or two kilowatt hours per day—a little less than half the amount of water the average person needs per day according to the United Nations, whereas a large multi-dish installation could provide enough water for a town.”
