It is possible in theory. Just think of solar cells that harvest wireless energy from the sun...
But if you transmit 1 W over 1 km, you will probably receive 0.00000000001 W (or something like that).
Wireless transmits energy, otherwise it would not transmit anything.
Take some distance from wireless systems, look at the physics.
There are tiny little guys called photons or electrons running. Even if you are a particle, running requires energy. If the electron or photon little guy bangs into an obstacle (including electromagnetic ones), it transfers energy, as in a car crash.
The detailed question behind your general question (where the answer is yes, because of the above) is how much energy is transferred?
This is a complex question which has to do with link budget analysis, including propagation loss. Look at satellite or microwave link budget analysis for an easy to grasp method.
Adding to the answer given by Emil, try to retrieve articles about lasers used for power. Under US president Ronald Reagan, there has been a program knick named "star wars" which included considering power lasers for military (destructive) purpose.
There is the nicer eye surgery with lasers, which focuses energy(heat) in one point of the eye. Ophthalmic surgery... Recent Nobel Prize in physics.
Look at physics to get your specific answer
Nikola Tesla states that he did actually send power wirelessly and to a large distance , but there is no evedince yet of such claims even though it would be classified and hidden from public . I work in the domain of wireless energy especially the ipt method and was able with 200 watts of energy transmitt up to 10 meters recieving 5 watts by strongly coupled magnatic resonance. But i want to know for sure, a clear of evedince of its possibility for larger distances...
