    Here's one use for it.

    I can think of a few serious uses as well. Gold melts at 1850 degree's F so it would be a great fuel saver for people who refine it from electronics scrap. Lead melt at 621.5 °F so it could be useful for molding it. Also solder melts a much lower temperatures then both of those so I bet it could be used to depopulate a circuit board really quickly although the fumes and the bright light might be a problem. Maybe it would be ok if you wore sunglasses and a Full-Face Respirator.
