It won’t fly further than a headline, never a practical one. The biggest issue remains (after solving the other two) in drones now is endurance, and unless a breakthrough battery technology changes that, all these cool concepts will never materialize.

I think battery life is a key limiter for this technology but how much time does it need? Something so small that can fly for fifteen minutes to collect intelligence et. al. might be sufficient. For example: a situation in which it is not safe to enter and detection would make it even less safe, ergo using something so tiny for only a few minutes could give valuable feedback to the user.

This is the size and sort of drones a unit would use for scouting the local area. The range isn't great, but it is suitable for that and less conspicuous than the gas-powered drones used 15 or so years ago and the buzzing quadcopters of today.

Power line perch recharging is the solution.

Did you fly further than the headline?

> The O1 drone weighs 1 pound and can fly up to 10 kilometers, which is a little more than 6 miles, for over an hour, according to a company fact sheet.

These are winged drones. Gliding takes no energy. Maybe you're confusing drones with quadcopters?
