Navy looks into UV cloak for stealth aircraft

The Navy's invested good money in the F-35 Joint Strike Fighter, which obscures radar waves and redirects engine heat to evade recognition by infrared sensors. But that stealth flier is still vulnerable to another type of detection: UV sensors. The Pentagon recently began soliciting proposals to develop a device that cloaks aircraft from ultra-violet detection systems. The hope is that such a technology could shield aircraft from missile seekers that scan the sky for telltale "UV silhouettes." According to the call for research, the solution could involve a device that disperses a cloud of quantum dots or other materials to veil jet fighters in a shapeless mass of UV shadow. Given that this is a rather daunting task, it's not surprising that the development timeframe and projected cost are still up in the air.

PhoneSoap Cleans Your Phone and Charges It, Too!

Posted on by

Many people have close relationships with their smartphone. They carry it around with them every day, press it to their cheeks at least once every few hours to make a call, and poke or tap at the screen every few minutes or so to check their email, browse the Internet, or read a message.

You should be aware by now that your smartphone has probably accumulated the growth of a ton of bacteria over the course of you using it excessively each and every day. I don’t even want to begin imagining all the microbes and bacteria that’s breeding in between each key on the keypad or around the grooves of its buttons…

Good thing there’s someone out there who wants to come up with a way to “wash” our phones (without getting them wet, of course) with the PhoneSoap.

Phone Soap

PhoneSoap is a charger and sanitizer packaged in one neat, little box. It uses to UV-C light to kill any bacteria and viruses that might be living on your phone. The UV-C light is 99.9% effective at killing bacteria and viruses, and since it doesn’t generate any heat, it doesn’t put your phone at risk during its sanitizing cycle. At the same time, it can charge up your device, since the box allows access to both a micro USB cord and Apple’s 30-pin USB cord.

PhoneSoap is currently up for funding on Kickstarter, where a minimum pledge of $39(USD) will get you your very own PhoneSoap.
