Todd Dabney, who’s been going to the Burning Man festival since 2011, needed a way to keep his tent cool under the baking Nevada sun. So the IT consultant created what he calls “the ultimate swamp cooler” out of a heavy-duty plastic storage container, pumps, tubes and a fan.
Powering the device is a 385-watt JinkoSolar panel that he snapped up on Craigslist several years ago from a nearby seller for US$100 (RM440). Dabney recalls that the seller was upgrading his solar array and getting rid of his current panels, which were about five years old.
