Still using my old MIOX generator. Lightweight, compact and tough as nails, and just all eat up with techno cool factor. Uses electricity from C23 photo batteries to hydrolize a brine solution you make from rock salt and raw water.  Click a little button one to four times, depending on how much water you need to disinfect.  The little bit of water starts to bubble and foam, and the smell of chlorine fills the air.  Nearby hikers start sniffing and turn their heads to see where it's coming from.  Folks gather around to watch.  Dump the solution in with your raw water, wait a few minutes, and you've got clean disinfected water.
