I remember now what I think the thing was with Voyager (and getting around the warp 5 restriction). "Organic gel packs". Basically, they throw the word "organic" into the technobabble to connect in the viewers' minds with organically grown food etc., with organic farming being less environmentally bad or damaging. Oh, it's"organic" warp drive, so it's harmless now. I have to admit though, it's effective enough as smoke-and-mirrors BS to get them out of a tight spot. They probably could not have done better. The gel packs are strange and interesting enough to sell it. How they function as machinery, though, I have no clue.
