CrazyCap UV Water Bottle Purifier
Doesn't sound so crazy to me to want clean drinking water. But maybe the CrazyCap, a UV water purifier that screws right on top of your water bottle, takes its name from the anticipated public response to hearing this little gadget can achieve 99.9996% sterilization of bacteria- and virus-contaminated water in seconds: "That's crazy! I'm Brian Fellow!"
The CrazyCap's built-in UV light operates just like the technology hospitals use to sanitize their operating rooms does. You've also probably seen the UV approach in other personal sanitization tools, such as the PhoneSoap smartphone sanitizer and charger and the SteriShoe shoe sanitizer. The CrazyCap is made to fight and kill viruses and bacteria such as E-Coli and salmonella using deep UV spectrum in the range of 278nm. It sterilizes both the water, and the water bottle itself, but does not remove particulate matter and/or chemicals (e.g., fluoride and chlorine) from the water.
The CrazyCap comes with a water bottle in your choice of colors, but is also sized for use on existing bottles with cola-top-style heads. The rechargeable CrazyCap uses a 500mAh li-ion battery that lasts for about 7 days per charge, and has a 500,000 water treatment lifetime.
