Money making idea, if you have the know-how on how to do it…
Drone manufacturing is NOT going to stop, and the drones are getting smaller and faster everyday, eventually they WILL be used in everything from police actions, to possibly war or skirmishes…
Develop and build a 1/2 mile drone destroyer, pin point EMP(best) or some other method for public use, small enough to wear on your arm under your shirt or in a hoister…will be used as a deterrent against anything and everything that invades your personal property(drones wise)…can be treated it like buying gun(I guess).
