Overhead Catenary Cables to Charge Electric Lorries.

Zoomup
So, what do readers think of this idea?  Surely those large pantographs cause high wind resistance? Perhaps if the lorries were put on steel rails they would be self steering and free up the roads.

    Thinking further about this with reference to Mike's Solar PV and tingles from the flashing post.

    How would you deal with leakage/unbalance currents to avoid the vehicle metalwork rising above normal earth potential especially if one pantograph lost contact with it's wire? 'Traditional' trolley buses operate at 600-750V DC apparently without problems. Would higher voltages and AC cause bigger problems? Conductive tyres could deal with small leakage currents but what about actual faults in the system? Conventional electric rail systems always have a good ground reference.


    Best regards
