Well, yes, moving tens of kilowatt-hours of energy in milliseconds wirelessly to a moving target with a lithium based rechargeable battery is an unsolved problem.
Who woulda thunk.

- cogman10 7y agoThe problem is cost and complexity. These things need a load of copper wire to make a loop, so if you are laying something like this down every 4 feet, it translates into a boatload of material (think 400ft of copper per 4ft charge) (That is being driven on... so definitely a possibility that they require regular maintenance).
