Gadgets and Gizmos (India) - - CONTENTS - MA­HESH KAPASI, NEW DELHI

When I read the story on mo­bile op­er­at­ing sys­tems (“What the new mo­bile OS is all about”, De­cem­ber 2011), I re­alised that per­haps the mo­bile phone can be­come a weapon against ter­ror­ism. Some­one can in­vent a phone that, per­haps with elec­tronic waves, can smell out TRDX and other ex­plo­sive ma­te­ri­als, and de­ter­mine its ex­act lo­ca­tion. These can be used by in­ves­tiga­tive agen­cies and they can be placed at var­i­ous spots—crowded places, trains, air­ports, on buses, etc. A beep or a red light can sig­nal the pres­ence of ex­plo­sives. Such a mo­bile, if man­u­fac­tured, can help the au­thor­i­ties lo­cate and defuse bombs and help save in­no­cent hu­man lives.
