These water makers may not end the severe water shortage, but they can decrease the demand on our shrinking potable water supplies by providing useful conservation measures for drought-ridden communities. Water makers are providing drinking water to some of our troops in Iraq and have the capability to provide entire small villages with potable water when natural supplies are nonexistent or polluted.
Water makers are not a new technology. Fans of George Lucas's Star Wars may remember the home planet for the Skywalker family and Ben Kenobi was Tatooine, where the poor inhabitants were mostly moisture farmers who harvested water vapor from the atmosphere rather than growing crops by using a moisture vaporator. The harvested water was then used to recharge groundwater basins and reservoirs.
