Crazy Physics Idea - 2

Just think....we are able to get energy out of tidal waves, pick up elecromagneticwaves using antennas...Would it be possible to pick gravitational waves??The gravitational filed is being continuously diturbed by motion of variousmasses....If we were able to pick these waves , we might be able to energy out of themThese waves will be very difficult to pick, since stronger fields likeelectro magnetic fields dominate.Also when we are making a detector for gravitational waves, we have to make sure that it doesnt get distracted by EM field..For this purpose we would have to use a neutral material like neutron rod in vaccumto detect gravitational waves...But there is still a problem that the Strong nuclear attraction between neutronsin the neutron rod might prevent them from responding to gravitational waves
So probably we could try to find the variations of the position of a neutronin vaccum devoid of fields other than gravitational filed...
But still when we try to measure the variations of neutron position, the photons usedfor this purpose might cause disturbances which might prevent us from picking up gravitational waves
But this can also be helpful...in the sense that the photon used for measuring theneutron position will also produce a gravitational wave which will affect theneutron
But again, the collison might be stronger than the disturbance due to gravitationalwave
