I severely doubt that, even more if the fields are static.
The best argument I have seen for such a device is that of Woodward, 
which does not seem to have gone anywhere.
At the time I tried to test his theory by two different methods and 
failed. Seems even he has conceded that his initial positive results 
were experimental error (other sites)
