my idea is for personal body armour made out of carbon fibre and kevlar, ultra thin and can be worn under your shirt without anyone knowing, can take a 9mil slug....also has arm and leg extentions as accessories. Can be cooled and heated with evironmental controls and has a back to base mobility connection for tracking. Is there technology that can do this? Another would be an Ap that can convert an mp3 to tab for all the music parts, recognises the frequencies and writes out the tab parts for everyone to learn. what else needs to be invented?
