  • The voltage being sent down would have to be really high to avoid loss going through such a long and probably thin cable. Like the difference in voltage loss going through a 100’ romex cable of 10-gauge wire with 12v DC vs 120v AC - you just can’t do it with 12v DC because the loss is far too high, but it’s no problem with 120v AC.

    Magnify those losses times 500 for your 5000’ cable… maybe you need a 5000v line… then you have a dangerous high-voltage line flying around in the air. High-voltage transmission lines can arc to ground if they find a path, even though they’re insulated wires.

    But I guess those guys probably know about that stuff too.

    Right, it’s a matter of physics and actual danger mitigation. Light is absorbed by black colored clothing, making an effective camouflage in the dark. If you camouflage yourself in the dark and walk in the road, you increase your chances that drivers won’t see you before it’s too late.

    No sane parent would teach their child that it’s the car drivers’ responsibility to not hit them, placing all burden for their safety on drivers. Instead, we teach them ways to be careful to reduce the danger. Safety precautions are not based on “how it should be” ideals. They are based on practical ways to reduce dangers.
