David Kamen and Coca-Cola Take On World’s Clean Water Shortage With Slingshot Purifier | Singularity Hub
What is Slingshot and how does it work? To quote the Grateful Dead (apologies), it’s just a box of rain. The water purification system takes contaminated water (virtually anything wet in fact—no source is too dirty), vapor distills it (like the sun), and cools the resulting “clouds” to recondense water pure as rain. All that for the energy-cost of a hair dryer.
Slingshot vapor distills contaminated water, cools the vapor, and re-condenses water pure as rain.
Water-borne pathogens cause roughly 50% of the world’s disease, and Kamen hopes Slingshot can put a big dent in that number.
