Getting foreign gadgets to play nice with the local power grid is a nightmare any time you travel internationally. Here why every country on the planet except yours totally screwed up indoor wiring. In the early days of the electricity craze, just after Nikola Tesla and the Westinghouse company wiped the floor with Thomas Edison DC power scheme, inven stanley cup tors around the world began working on ways to harness the fantastical energy for household work. Everybody had a different idea of how to do so. In fact, when Westinghouse standardi stanley website zed its operating frequency 60 Hz, it snuffed out nine other potential frequencies. The same is true for the worldwide standard of 120 and 220-240V systems鈥攖hese two beat out ten other options to become the de facto voltages. However, Germany paid little heed to the US choice of a 60 Hz frequency. They instead decided on a 50 Hz standard because that what was already being used by the BEW company, which held a monopoly on German power generation and transmission, in 1899. The 50 Hz scheme spread through Europe while the 60 Hz spread through North America. They became competing, nearly-universal standards鈥?20V at 60Hz in North America, 220-240V at 50 Hz in Europe. The other problem with early electrical systems: stanley cup There was no easy way to tap into the power supplying small appliances. If you had a table lamp or a hair dryer or some other low voltage gadget, you ;d have to knock down a wall and hard-wire it into Aovv 8220;The Flex Duo system 8230; allows one to split the oven with a ceramic divider to create two separately controllable cooking cavities, complete with their own convection fans. 8221; Whaaaaa the future.

When carbon fiber was first trotted out in solid rocket motor cases and tanks in the 1960s, it was poised to not only take on fiberglass, but also a whole host of other materials. What happened 50 years later it still an exotic material. Sure, Batman got it in his suit, expensive cars feature smatterings of it in their dashb stanley cups uk oards and performance parts, but at $10 a pound on the low end, it still too pricy for wide-scale deployment. We ;ve been using th stanley cup is stuff for decades. Where our materials science Moore Law to make this stuff cheap Why is this stuff still so expensive Turns out that even half a century later, this stuff is still a major pain in the ass to make. Before carbon fiber becomes carbon fiber, it starts as a base ma stanley cup terial鈥攗sually an organic polymer with carbon atoms binding together long strings of molecules called a polyacrylonitrile. It a big word for a material similar to the acrylics in sweaters and carpets. But unlike floor and clothing acrylics, the kind that turns into a material stronger and lighter than steel has a heftier price tag. A three-ish-dollar per pound starting price may not sound exorbitant, but in its manufacturing, the number spikes. See, to get the carbon part of carbon fiber, half of the starting material acrylic needs to be kicked away. The final product will cost double what you started with because half burns off, explains Bob Norris of Oak Ridge National L
