Scientists at UC Berkeley and MIT have demonstrated a water harvester that uses only sunlight to pull liters of water out of the air each day in conditions as low as 20% humidity, a level common in arid areas.
Farmers in many places have found additional sources of income by allowing wind turbines to be built on their land. One example is the Amazon Wind Farm, which is a massive project of over 100 turbines near Elizabeth City, North Carolina. The 494-foot tall turbine towers scattered over 34 square miles are rising up above farms that grow corn, wheat and soybeans. It is the first utility-scale wind farm in the Southeast.
