Well they already explained how lightsabers are made in the expanded universe, and they proved on a science TV show that it is possible to make one, anyway the reason I am asking is because I plan to have a space pirate faction and energy swords would help keep the sci fi aspect while still being very much like pirates, I also have a way of explaining how they create the energy swords

Out of curiosity, who did you plan your pirates to be attacking?

Redspace might be a good source of easy targets, given how many Ljikoril wthpships there are floating around in otherwise empty systems.
