Bewra,
Unless the superpower nations were testing their power distribution and how the public will react, I will suggest that you base it on power outages, or an smart controller for solar power or a project on separation of signals whose frequencies are fairly close to each other. Most projects on portabilities i.e: a power pack about the size of a pack of cigarrettes that may jump start your car battery. etc. shoot for the big and for what require the most of you...Good luck!!! :idea:
