5. Bright Idea: the Water Cone October 30, 2006Posted by Matt Fleming, PsyD in Product.
Post #4 reminded me of something I read about in a magazine some time ago, the Water Cone. This invention turns salt/brackish water into potable water via solar condensation. Genius, and also altruistic. But, there seems to be a potential problem: it is cumbersome and hard to transport.
Possible improvement: make it foldable/collapsible, like a translucent umbrella, with pockets at the base to catch the condensed water.
