An Afghan designer based in the Netherlands created “Mine Kafon,” a wind-powered landmine detector using inexpensive, prefabricated materials. Bamboo sticks with plastic feet attach to a plastic core that holds a GPS tracker. When the machine rolls over a buried mine, the mine explodes — with no loss of human life or limb. Removing a landmine currently costs around US$1,000. Massoud Hassani’s device was built for around US$40. After initial testing with help from the Dutch Ministry of Defense, Hassani is currently working on a second version.
