More Unconventional Security Solutions

By Matthew Harwood

Yesterday, Security Management let readers in on a new ATM pioneered by South African bank Absa that squirts pepper spray at anyone that tampers with the machine.

Just a day later, surfing the Web has uncovered two more security technologies. The first comes from India, where the government will deploy a super-hot chili hand grenade for counterinsurgency and riot control, reports Asia Times Online.

Even ordinary chilies cause severe itching and burning of the eyes. The chili that the DRDO is thinking of using - the bhut jolokia - is no ordinary chili. Grown in India's northeastern region, it is a thousand times more pungent than the hot chilies used in Indian cooking. The word bhut means ghost and those who have eaten it say that the chili was aptly named. It would scare even a spirit away. When you bite into a bhut jolokia, it bites back at you. Eating a bhut jolokia is an all-out assault on the senses.

The chili hand grenade works much like tear gas, making the eyes water and in some cases inducing a semi-conscious state.

R B Srivastava, director of life sciences in the government-run Defense Research and Development Organization (DRDO), told the Times Online that the grenade will be used "in forcing militants out of their hideouts."

Further east, a ward in Tokyo is exploiting the structural difference between teenage ears and adult ears to combat vandalism in Kitashikahama Park, reports The Washington Post.

Authorities rented a British-made Mosquito MK4 Anti-Vandal System and screwed it into a wall not far from park toilets. The device emits a high-pitched, highly irritating whine that has a frequency above 17 kilohertz. Most adults cannot hear it, but teens can.

Seven days a week, the whining begins at 11 p.m. and continues until 4 a.m. Video surveillance cameras monitor park buildings. And Kitashikahama Park empties out.
