Water Abundance competition by Xprize intends to reward and to donate to projects that make water abundance possible. This year, the judges have chosen the finalist and the winner in these two-year-long water extraction competition. The Skysource/Skywater Alliance has earned $1.5 million for their WEDEW (Wood to Energy Deployed Water) technology Skywater that converts the particles of air into drinking water. This device produces at the minimum, 2,000 liters of water per day from the atmosphere using 100 percent renewable energy and some electricity. The technology is safe for people to use and it only requires to be stored in the shipping container.
Although the concept seems complicated, the underlying idea is very simple. The technology imitates clouds firstly by cooling the warm air to a point where it will become dense and collecting condensed liquid in a tank. The Skywater device uses available and easily obtainable biomass as a fuel and converts them into energy. You can use any organic material such as wood, grass and other obtainable organic biomass. The device also uses electricity for power, but it uses it efficiently at the cost of two cents per liter.
While this device is great for fighting the water crisis in Africa and other developing countries, it also helps with cleaning the environment. Dead wood, paper and grass pieces that could otherwise catch a fire and release more CO2 are used to create water. California alone has 66 million dead trees that catch a fire every other year.
The machine is done in carbon negative technology meaning that although it uses a lot of energy to create a clean water, it does not output CO2 like any other electric devices at your home. The device outputs a charcoal which can foster plant life and store carbon. The solar power and batteries are other available alternatives in places where dead biomass is not available to make the system work.
The founder of The Skysource/Skywater Alliance David Hertz says that the non-biomass version of WEDEW is already in use in developed countries. He plans to use the device in places where water resources are scarce and clean water is not easy to obtain. The team will use the prize money to rapidly develop and deploy the units worldwide in partnership with nonprofits.
Clearly, the global water crisis isn’t resolved yet. Globally, 844 million people lack access to clean water. Worldwide, 2.1 billion people still live without safe drinking water in their homes and more than 1 billion people still have no choice but to defecate outside. A Skywater Emergency Services Unit can produce 450 to over 900 gallons in a day. That is a small step in solving the emerging water crisis and poverty, but the technology is indeed promising.
If you want to help to resolve the water crisis and be among the noble companies like Skywater you can donate for clean water or run or walk in the Global 6K for Water May 19 to bring clean water to children around the world.
