Yes, it does look like something "Jordy" from Star Trek would wear but it's actually a gadget that eliminates bacteria, viruses, mold and dust mites with just a few waves, as per the makers of this gadget.

Called the Germ-Eliminating Wand, the germ cleaner is powered by 4 batteries or an AC adapter and uses a 6" long UV-C light bulb to disinfect carpets, kitchen surfaces, bathrooms, bedding and other surfaces without using any chemicals. The wand is also programmable for use in 5/60 minute intervals and has an automatic shutoff. 

Interesting, we think. Grab it for US$99.95 from Hammacher Schlemmer
