Query: Gravitational Radiation from Oscillating Gravitational Dipole   The concept of Gravitational Dipole is introduced starting from the recent
discovery of negative gravitational mass (gr-qc/0005107 and physics/0205089). A
simple experiment, a gravitational wave transmitter, to test this new concept
of gravitational radiation source is presented.
