A bucket with a cover grows trees in arid places

water pot for growing treesPieter Hoff won Popular Science magazine’s award for Popular Science magazine’s award for the 2010 Best of What’s New Innovation of the Year (the picture is theirs).

The cover on the bucket has 2 holes in it so it can catch water from rain or condensation once a sapling or seeds are planted in it. There is a wick that drips enough water onto the plant to allow it to survive in this micro-climate while it grows tap-roots deep enough to find moisture. It will also last for about 10 years so can be used at least 10 times to establish a new tree. They’ve been extensively tested over the past few years.

The Guardian has an interview with the inventor here and here is a lovely gallery from the official Groasis Webite. Details of various projects are here. Mrs Green will be keeping an eye on this.
