Summary: <p>Dutch bulb grower, <a href="http://poptech.org/pieter_hoff">Pieter Hoff</a> has an idea about how to make deserts bloom: capture the humidity in the air, store it in a box, and use that condensation to water plants. He calls this box the Groasis waterboxx and he thinks it can change how we feed the world and reduce greenhouse gases.</p>
