Massoud Hassain "Mine Hafon" invention. There are over 110 million anti-personnel land mines scattered across 70 cuntries. Manny of these mines have been underground for 30 years, and still remain active. Massoud Hassain has developed a cheap, effective method to combat this devastating problem. His "Mine Hafon" is a cheap, light, wind-powered mine detonating device. It's composed almost entirely from bamdoo and biodegradable plastics. At 70 kilograms, his invention is light enought to be propelled by a normal breeze, while still being heavy and big enough to acctivate mines as it rolls over them.
