Gravitational Waves: Experiments to Produce and Observe

[JF131]

My understanding is that there is currently a large amount of money being spent on different experiments to detect gravitational waves. From all the articles I've read , they all describe these waves getting weaker as you travel further from the source. So my question is does anybody know of any experiments to actually produce and observe G. waves rather than trying to observe a minute amount of space-time distortion from a source that's light years away??

Laboratory produced gravitational waves would be impossibly weak in amplitude for modern day detectors to go up against. Astrophysical events on the other hand can be extremely violent and produce gravitational waves with amplitudes that are at least reasonable with regards to future prospects; see section 9.3 of Schutz "A First Course in General Relativity".
