Yesterday I heard a presentation at the Chabad house in Oxford from the CEO of the Airwater corporation. I found it of such interest that I cannot resist the impulse to blog about it! You plug the machine into a power source and lo and behold you've got pure drinking water. The machines scale up from household units which can replace the home water fountain to devices which provide water for a whole village community or a disaster site! The power source can be electric or wind. Continuous development is driving down the power requirements.
