I just read an article on cargo ships using kite-like sails to reduce fuel consumption, with computer systems to choose the type of sail, the height to fly it, and whether it's worth making course corrections to take advantage of wind.
Can't find it, though, so I'll just mention it here.

Mystery particle?? It was a solar sailer (not unique to or even original to ST), and they are powered by photons. That is, light.

Thanks Dag and Kwea. I've heard of lots of attempts to bring wind power back to shipping, but what's neat about this is that an existing cargo ship can be retrofitted. Also that the "sail" can be taken down completely for motoring, with no masts or anything.
I hope it gains acceptance. It's about time sail power came back.

I think she might be referring to the episode of DS9 where Captain Sisko re-creates an ancient Bajoran light ship. While trying to fly around the solar systen, he and Jake hit a tachyon storm and are swept at FTL speeds towards Cardassia.

Solar sails are real idea, in that it should actually work if you were willing to put the effort in. NASA has done preliminary work on the idea.
