World Economic Forum reports about a startup making solar panels that pull clean drinking water from the air. Zero Mass Water produces solar panels that pull water out of the air, filter it, and deliver it to your home faucet. The panel arrays, known as Source, use sunlight to harvest water from air vapor. The harvested vapor is then sterilized and turned to liquid, which is stored in a reservoir that connects to your home faucet. For $2,000 (plus around $500 for installation), Source can deliver about 2 to 5 liters of water daily. That\’s the equivalent of up to 10 water bottles.
Now they have a sensor that allows customers to monitor the quality and safety of their drinking water. Customers with a Source panel array wind up spending far less than those who purchase plastic water bottles. Moreover, Source panels last around 20 years.
The company represents the technology as a way to help solve the global water crisis, which has left more than 2 billion people without access to safe drinking water in their homes.
