Questions
Since it's RF, will there be communication built in, so that the provider be able to limit power to subscribers? Alternatively, if anyone can use it, who pays?
The other problem is that (it seems to me) a system like this is equivalent to leaving your cell-phone charger plugged in all of the time. Electricity is being consumed even when it isn't being used, because the load is there whether anyone is recharging or not.
Perhaps those issues can be worked out. As a subscriber starts down the road, the system begins to provide power along the vehicle's path, and only as it approaches the next underground plate is that plate charged.
There are certainly a lot of routes to practical electric vehicles being explored! My personal bet is on batteries that will allow a 1000 mile or more range, but that are no larger than the current battery packs.
