Atmospheric water generators take humid air and convert it to water.
Nashville, Tenn. (PRWEB) January 04, 2013
A new Columbia University study, as reported by The Stream, a daily digest spotting global water trends, states that temperatures bumped higher by climate change will increase evaporation levels from plants and soil in the American West. This situation is drying out the land and reducing water run-off into rivers and streams by about 10 percent in California, Nevada, Colorado River headwaters and Texas.
Power4Patriots believes that this water depletion, as well as the potential for greater water shortages if a weather-related disaster or a terrorist attack occur, should get people thinking about taking their water supply off the grid. Best known for teaching people how to build their own environmentally-friendly sources of energy so that they can slash their power bills and be safe when power outages occur, the company also wants to help people be prepared to deal with emergencies including water shortages.
In addition to having at least a 30-day supply of water on hand, Power4Patriots offers 3 tips for taking a water supply off-grid:
1. Have a well and a cistern in order to pump and store water. If possible, power the pump with an off-grid solar power system in case of power outages. Consider adding a backup storage tank of at least 500 gallons.
2. Tap a local spring for water, which can be found through local geology maps. A spring could be tapped through a drill-hole, or discover where it reaches the surface and divert or bottle it. A siphon and five-gallon drum will be useful.
3. Capture rainwater. This is probably more practical for most people. Set up catchments under roof gutters and fill them during the next storm. Use airtight containers for long-term storage and employ a simple water filter system.
Additionally, water can be generated from air. Atmospheric water generators take humid air and convert it to water. With built-in filtration, they can produce anywhere from three to 10 gallons per day in the right climate, and they have the added benefit of dehumidifying the air. Unfortunately, these machines use a considerable amount of power.
