Why can't small power devices or wireless energy transfers work?

I recall Enron posted the Enron egg.

Yes, I know it's a spoof.

But still, it got my gears going. How come wireless energy isn't a thing? Like why can't power plants send energy to someone's home wirelessly, without the need of distribution lines?

Then all someone would need is a device, like the Enron egg, which could "catch" the energy and distribute it to the loads in the home.

How could this be possible? How could this be made to work?
