Milligoon .... we weren't suggesting it would be done by masts (hence comment about walking past a charging spot every 4m down the street) .... for contactless charging from plates set in the ground there will still have to be massively powerful radiation across the gap to the pickup plate under the car with the resultant loss and leakage .... when you're talking multi Kw of radiation that RF leakage is not something I'd like to be around .... one thing charging your electric toothbrush or phone with mw sat on a pad overnight ....the power transfer to charge an EV in a reasonable time is another thing altogether.
We shall see if contactless charging gets beyond the experiment stage to working examples in the wild
