 Quote by djg1508 In what way "revise"?
You know: "revise". Review, check, reassess - go back to the materials where you formed the ideas with a critical eye to your current understanding. You made a distinction between energy and mass for example. I will not go further here as I don't want to stray too far off topic. If you are still puzzled, after your review, feel free to make another thread.
 I'm just interested in what set of physical\mechanical attributes and their distribution in relation the vessel would need to exist in order for the vessel to begin to create the space-time distribution around itself that would propel it in a given direction.
I get that and have answered to this point as clearly as possible.
 The emphasis has so far been on the impracticalities of; Producing the energy required Obtaining right kinds of 'exotic' matter Handling the amounts of 'exotic maater' The radiation problems The problems of destroying your destination etc...
etc etc... yeah I know.
To be fair - these are part of the set of physical\mechanical attributes and their distribution in relation the vessel that would need to exist in order for the vessel to begin to create the space-time distribution around itself that would propel it in a given direction.

Your question amounts to "if we have solved all that [on your list above] what else is needed?"
 I was just wondering, theoretically, what you would have construct (schematically) from an engineering point of view in order for the vessell to to go! Or rather space-time go around it.
The pop articles usually include an artists impression of the kind of thing you'd get if the exotic matter took a form similar to normal matter.

Bottom line - the engineering of how to get the distributions needed, never mind how to turn it on and off, depend on the exact form that the negative energy takes. Therefore - nobody knows enough to answer the question you have posed in the way you seem to want - i.e. in an "engineering/schematic type of way.

 So far the diagrams show the shape of the warp bubble and how space-time would need to be warped around with a dip at one side and a peak at the other etc... but I cant see any indication of what (mechanically) the ship would need to be doing to create this shape. (theoretically of course)
The space-warp diagrams can be misleading. The actual bubble is four dimensional and the articles can only print in 2D.

That is partly why I'm not going into great detail about the exact shape - it will be a 3D structure that looks like a pair of toruses with flattened crossections. No doubt the distribution will get tweaked further as more people work on the problem.

If you want the details - go to the original papers and learn the math.
