These autonomous drones can recharge themselves from power lines

    This doesn't seem like it would be legal in the US. Compensation would need to be negotiated

      It’s probably more of a tool for government or civil services in which case that’s up to them

        In that case it could probably work much like streetlights where the municipality just pays a flat rate to the electric utility per unit based on how much power it's expected to use. But in this case, there are probably a little bit more complicated factors like the liability of causing damage to a transmission line.

          If it catches on I suspect you’ll see a redundant line added in areas that would need frequent use either due to projects or issues, but yeah there’s a lot of interesting things to look into here

        Saying that is like saying my house isn't taking power directly from the high voltage lines because there's a transformer between the two (transformers function the same way). Sure its technically correct but that inductive charging will put a (tiny) load on the power lines; this isn't a free lunch.

        Unfortunately there's no such thing as free energy. These drones are taking (an admittedly small) amount of power out of the grid by landing on these lines. That being said, its likely pennies of electricity per charge and is peanuts compared to line losses. You could easily bake in the costs to an additional tax or license renewal fee when purchasing one of these drones for commercial work.

          I'm not arguing that there isn't any energy exchange. I should have included that in my oc. In my mind that cost would be nothing compared to having replace those transmission cables.

    I like it, it's like our own robotic birds sitting on power lines.

    I watched the video and it looks like its basically electromagnetic induction through what amounts to a current clamp and a motor to charge the drone's battery? Do I have that right? Whatever it's doing is pretty brilliant in its simplicity.

    I don't think there's much that utilities with above-ground power lines can do to prevent energy leeching like this. It'd be incredibly expensive (and stupid-looking) for utilities to try to physically block this. Wouldn't interacting with the electromagnetic field itself be enough for a different kind of energy harvesting to take place using eddy currents? So just having an EMF would be a method of leeching? I have so many questions.

    Not the least of which is: have birds been harvesting energy from power lines like this all this time??? Have they been robots all along??? (Just kidding, we all know they sit inside the electromagnetic fields to orient themselves for navigation.)

      I would expect that the cheapest way to protect them would be the legal system, either the company manufacturing it or the users.
