In these days of so-called "Wireless connection" via radio signals, I'm surprised that we still suffer from having cables draped all over the place to get connected to "things"!
Enter the ghost of Nicola Tesla, wandering onstage again...
He was the first and foremeost promoter of "wireless power transission". Have a master Tesla coil in a fairly central location, every house has another in the attic to supply that house...essentially a long range transformer with the secondaries in the houses. Then you can equip each device with a coil of it's own, bingo! Wireless power transmission! All just a matter of the right frequency ranges for longrange transmaission, and the right number of windings for each coil to make the proper voltages.
All denied and quashed by the power companies, for one cannot monitor the usage rate of wireless transmission of power, and therefore figure out how much to overcharge the customers. The government wasn't pleased either....no charges for the power compainies, less taxes for the government to get from us. But look up who owns most of Tesla's patents these days...Circle-Bar-W (Westinghouse) is one of the main owners.
Poor Nicola was a man WAY ahead of his tme, brilliant, and somewhat insane, sadly, and too naieve to protect himeslf from the greed of his bosses...
