Air 2 Water has developed a machine that makes water from the air. Plug it in, and water comes out. No lines to connect, no bottles to stick on top. The machine is a dehumidifier with a water purifier, so that instead of throwing out the pan of water sucked from the air, it can be drunk. It is a perfect water solution for every office cluttered up with huge water cooler bottles. It'll produce 20 liters of water a day in 70 percent humidity, which is about the amount that comes in one of those five-gallon bottles, but without the waste or transportation emissions. It'll even produce hot water. There's a smaller countertop version, too.
