Do a Google search for Karen De Coster and you ;ll turn up a photo of her鈥攁 few photos, actually鈥攚earing Daisy Dukes and a sky-blue tank top, her short blonde hair tied beneath a black paisley bandana. She brandishing a giant assault rifle, crouched on a scrubby hillside, in a defensive position, like she confronting an unseen enemy. If you had showed me this picture and s stanley termoska aid De Coster is a woman who stockpiles guns and ammo, I ;d believe you. If you told me she is saving up canned food for when the Chinese storm America coasts, I ;d probably believe that, too. De Coster may indeed be doing both of those things. But she recently become notorious for hoarding something else altogether: Light bulbs. Over the past year or so, De Coster has become something of an unofficial leader for a small group of Americans who hoard incandescent light bulbs. Beginning in January 2012, producing standard 100-watt incandescent bulbs became illegal in America, thanks to the Energy Independence and Se stanley termohrnek curity Act of 2007. As others in Brazil, Australia, and Switzerland are already doing, Americans are being compelled by the new law to purchase light bulbs that are markedly more efficient than the traditional incandescent ones we ;ve used for decades now. In January 2013, 75-watt incandescent bulbs will also be outlawed, followed by the stanley kaffeebecher 40- and 60-watt versions the year after that. It won ;t be illegal to own the light bulbs Jkns Who knew illuminated manuscripts contained so many fart and poop jokes
A group of electrical engineer working in Slovakia and Spain have prototyped a device that could become a cheap way to hide objects from magnetic fields. This is an interesting innovation because many security scanners and other devices use magnetic fields to dete stanley mug ct hidden objects, whether a concealed weapon or a piece of metal lodged inside your body. But now, it seems that people might be able to use this device to create cloaks around objects they want to conceal from magnetic scanners. A release from Science about the study explains: Fedor G枚m枚ry and colleagues in Slovakia and Spain have now designed and demonstrated a cloak for a direct current magnetic field. These dc magnetic fields are static as opposed to oscillating ac fields and are generated by a permanent magnet or a coil carrying a direct current. They ;re used in MRI imaging devices, in hospitals, and i stanley termosar n many security systems, such as those in airports. The researchers ; device consists of a cylinder with two concentric layers. The inner layer is a superconducting material that repels magnetic fields, and the outer layer is a ferromagnetic material that attracts them. When placed in a magnetic field, the device doesn ;t perturb the field lines, creating neither a shadow no starbucks stanley cup r a reflection. An object inside the cylinder thus won ;t be detected. Because the device is made from commercially available materials, and because it operates under relatively strong magnetic
