I keep wanting to take a small inflatable blimp and have it fly around. Infrastructure would then be a small landing pad with an electromagnet to hold the buoyant blimp up so the fans don't have to continue to run while charging. For charging i've been thinking of using the same tech as wireless charging pads for cell phones. This means I'd need somewhere the blimp could find as home to land on. As far as helium replacement I haven't figured out a sane solution yet. Combined with this rfid improvement then I'd possibly be able to finally have a computer that i can ask "Where the hell are my keys" when I'm running late for work in the morning.
