ive never anyone dispute the concept, from what i understand its simply transmitting electricity through high powered radio waves, ive even got instructions on how to build an antenna to pull electricity from the radio and tv waves we use not, its not much, but its there, deosnt seem liek theres much research to be done
the problem lies in the fact that generating such high powered waves will cost some high powered money, so of course any company doing this will want to bill its customers, but AFAIK theres no way to see who is using your power, and how much they are using, also, because of the way this would work much of the energy broadcast will go to waste, beaming uselessly out into space, or into the ground, so its not a very effecient method
so essentially, until there is a way to generate enormous amounts of electricity for little or no money, this means of distributing the energy will be useless
