is wireless power transmission possible?

Certainly is possible. You can buy inductive chargers for things like cell phones and remote controls today. Whether it is practical and economic for large scale power transmission is another matter...

There's even been a NASA demonstration of an unmanned lightweight aircraft which was powered entirely by laser beam from the ground.
