Thanks Spacial Rift 47. I was hoping that someone like you would respond.
I guess what confused me is that, given my limited understanding, it seems to be saying that he believes it can be done with a positive energy density.
One of the diagrams (on page 31 of the PDF, but labeled as page 21 on the document) states:

[li]The figure depicts a modified Michelson-Morley Interferometer setup that makes use of a 1 cm diameter toroidal-ring of positive energy density on one leg of the interferometer.[/li]
[li]a He-Ne laser beam(λ = 633 nm) is split allowing one part of the beam to pass through the center of the ring and hence the spherical warp field region.[/li]
[li]This warp field region will induce a relative phase shift between the split beams that could be detectable provided the magnitude of the phase shift is sufficient.[/ul][/li][/quote]
It seems to assume that the effect will be produced with a toroidal-ring of positive energy. Is he simply wrong about this? Does the paper give his reasons for believing this? Am I just completely misunderstanding the whole thing (a real possibility)?
