The Mine Kafon -- currently in prototype stage -- is a low-cost wind-powered mine detonator with the appearance of a giant, spiky-armed tumbleweed. Its goal, according to creators, is to set off landmines by rolling over them -- which means innocent citizens in such countries as Afghanistan won't.
According to Kickstarter.com, the Mine Kafon is "a spherical mobile made out of biodegradable plastic and bamboo. It’s light enough that the wind would -- in theory -- push it around naturally. But it is also heavy enough to set off landmines as it rolls over them."
