Bill Gates and Blackrock are backing the start-up behind hydropanels that make water out of thin air

They are like solar panels, except they produce water.

Source Global's hydropanels create water out of thin air and bring it where it's most needed. The panels were invented by Friesen at the Ira A. Fulton Schools of Engineering at Arizona State University.

He turned the science into Source Global. The panels for the start-up cost $2,000 a piece.

We take sunlight and air and we can produce water that is perfect for drinking.

Source's hydropanels take in water from the air and pack it into a form that is 10,000 times more concentrated than in the atmosphere. The system uses the warmth of the sun to convert the molecule into liquid water and then releases it as pure water.

The Samburu Girls Foundation faced daily danger on their journeys to find water because of the 40 hydropanels installed by Friesen. They have their own source of water.

We can now make perfect water at your home, at your school, in your community, in a way that is really bringing it into the 21st century, said Friesen.

In 52 countries, Source's hydropanels are installed. The company has raised $150 million from investors, including Bill Gates.

This type of technology is desperately needed in places like India, where an estimated 800,000 villages don't have clean drinking water. Half the world's population will be in water stressed areas by the year 2025.

There is a domestic need as well. There are 1.5 million miles of lead pipes in the US, and about 750 water main breaks a day. He said that the business opportunity is enormous.
