Yes it is possible. Unfortunately it isn't practical. Too much energy lost, and the loss rate per meter increases per meter too. It just gets worse and worse.

I think microwave transmission is the most practical means we have, and even then it's still crazy inefficient, saying you could get 10kw out for 100kw in, over a 1km distance, would be a very generous interpretation of US navy tests.
