Bearden indicates that if you observe E = -dA/dt, you may create an electric field by varying the B field and hence the A field. Thus by having a secondary 'output' coil, this E-field may be harnessed and used to 'energize' electrons in the output coil rather like a current. The current in the input coil may be pulsed hence, if the input pulses are almost in a tophat-like fashion, you may produce a large dA/dt and hence large E field, with no B field component associated with the A field outside of the solenoid.
You don't have to put any extra energy into the input coil to do this, as the A field outside of the solenoid is a quantum effect that appears via gauge freedom, which Bearden claims is explained by quantum electrodynamics (the quantum version of classical EM) via the vacuum being occupied by virtual particles, including the virtual photons reponsible for interactions of electrons.
I've just received his book, 'Energy from the Vacuum' today through the post from the US, which I'm giving a read. I'm actually surprisingly optimistic and I'll probably be talking to the old profs in my former Uni about this.
