What if you ejected some sort of control wire when you turned it on? In that way you would be able to control its length. Then, you could use the anti-grenade shield currently being developed for British tanks along the wire. Although, there is still the problem of getting all the energy you would need to keep up the electromagnetic shield. There has been a patent for a really small vacuum energy generator, I guess that could fit into it and there you go, a light saber.

If the thing really does contain light how come the blades not invisible. Why does it glow if it contains the light???
