From an engineering viewpoint, it's not a very good idea....wires work so well for carrying electric current. Wireless signal transmission makes sense because the information is what is important, not the power being used by the transmitter. Wireless transmission of power itself is not a very good idea, because it is very inefficient compared to wires (I think the inverse square law has something to do with it?)

It would be fun to experiment with, and as suggested low power applications such as powering custom sensor circuits would be a more suitable application than the drive system, also more likely to be meet the rules.
