Tesla was just stuck on trying to transmit electricity.
If you think about all the money spent on telephone poles, rights of
ways, copper wire etc - if he could have perfected it - it would have

Dunno.. Transmitting electricity through the air strikes me as
quite lossy, and if using a broad pattern to enable many people to use
it, the amount of recoverable energy vs what is transmitted would be
fairly small. A large amount would go off into space totally wasted.
If his method were actually practical, I suspect someone would be
using it by now on some scale.
There are enough loss just using a direct connection with wire.
I can light a florescent light bulb using the energy from my
HF mobile antenna. But only if I have the tube right next to
the antenna. Five feet away, fugettaboutit..
