The idea of Thethered UAVs isn't new. Problem is probably the danger of high voltage tethers that they use.

Why do they need a high voltage tether? They don't need a high voltage battery.

To transmit power, its better to use high voltage and low current. Reduces transmission losses; uses much lighter cables. Then where the power is needed its stepped down with transformers or 'buck converters'.
