One of the dangers of Afghanistan’s war-ravaged landscape is the presence of millions of land mines, many of them forgotten until some innocent triggers their deadly attack. An Afghan designer has come up with a prototype device called the Mine Kafon, based on toys that he played with in his childhood, which might help safely locating these weapons:
It rolls like tumbleweed in the country’s windy landscapes but should have enough weight to trigger devices. The movement can be rather random but a GPS device allows it to be tracked and so a central computer could build up a map of safe trails. A detonation would destroy it but it just consists of rubber, bamboo and a small electronic device; inexpensive compared the lives it might save.
