Build a charging tether for a drone and have it fly for two hours above your head.
You could use a battery to power a power converter that took it down to USB charging power and then run that up the tether to the drone. Challenge would be distance because you can't really go more than 15 feet with USB signals but I don't about power.
It would be cool to have a drone up above your head and just have it stay up there for an hour or two and get a different perspective on the field or a place.
And it could be interesting to to maybe build pole and then do it 15 feet above the end of the pole and have all the power stuff at the end of the pole.
