Cool world-changing technology, part 1

Last Saturday I helped old friend Ted Tannenbaum celebrate his birthday – and learn that he had won the X-prize along with SkyWater partners Richie Groden and David Hertz. The competition asked designers to build a device that could extract at least 2,000 liters of water a day from the atmosphere (enough for the daily needs of around 100 people), use clean energy, and cost no more than 2¢ a liter. Their process uses a biomass gassifier filled with wood chips, coconut shells, or whatever biomass is locally available to run the air-to-water machine. As it generates power, it also produces biochar, a charcoal that can be added to soil to store carbon and help plants grow.

It's a carbon-negative technology, producing potable water and absorbing carbon from the air.  It's what you call a good thing.
