Looking like a usual grey shipping container, the Skysource box can do wonders. Through the engineering feat of David Hertz and his team, the device harnesses the power of condensation and can generate up to 2,000 liters of water a day out of thin air. The Skysource box heats itself up through solar power or biomass. Then, when cool air hits a surface, moisture from the air condenses, yielding drinkable water. The technology won the Water Abundance XPrize in 2019 for producing clean water at a cost of less than two cents per liter using 100 percent renewable energy. As if this wasn't enough, the company took the prize money to engineer more advanced technology called the "WeDew," which stands for Wood-to-Energy Deployable Emergency Water. This device creates heat from the local biomass of wherever it is stationed—be it wood chips, coconut shells, rice husks, or nut shells—and can generate up to 2,200 liters of water a day. After the biomass is vaporized, biochar is released that is nutrient-rich for the soil. The technology is versatile for arid regions, water-stressed areas, and even disaster relief.
