	It all depends on the numbers!  How close is the coupling, etc.  If you
can get enough power coupled to light a small pilot lamp it should work,
if the motor impedance is correct.  My guess is that it would quite a
bit or work to get anything to run.  

	In answer to your second question, yes.  Lots of people have done it
and reported results in the past.  Right now a friend of mine is
presently running a very low-power home made motor on the power he picks
up from an FM station a short distance from his home.  Motor runs on
about 100 microamps at a couple of volts, DC resistance is 600 ohms.
