Carbon fibers could soon become part of the energy system for the next generation of structural batteries. Researchers from Chalmers University of Technology in Sweden have discovered that carbon fibers can directly store energy working as battery electrodes, which could ultimately contribute to an overall weight-reduction in future aircrafts and vehicles. While carbon fiber has predominantly been used as a reinforcing material, the researchers found that they have the ability to perform more tasks like storing energy. After examining the microstructure of different types of commercially available carbon fibers, the researchers found that carbon fibers with small and poorly oriented crystals have good electrochemical properties but a lower stiffness in relative terms. However, carbon fibers with large, highly oriented crystals have a greater stiffness with electrochemical properties that are too low to use for structural batteries. The type of carbon fibers best suited to store energy … [Read more...] about Researchers Uncover Hidden Carbon Fiber Ability to Store Energy

Share Tweet Share Email Comments Print APEX, Nev. — The most striking aspect of the testing facility for the potentially revolutionary, multibillion dollar Virgin Hyperloop One in the Mojave Desert is that it is made up of a series of Big Top Fabric Structures, a super-size version of a backyard party tent. But the 40-acre site 29 miles outside of Las Vegas has everything engineers need to test the high-speed pod that runs inside a low-pressure tube: a 500-meter test track, which is about 1,600 feet; a mission control area about the size of a two-car garage, with 20 computer monitors and two large display screens; temperatures that can range from 10 to 127 degrees, sometimes with monsoon-type wind and rain, and several dozen tube sections about 11 feet in diameter, about 50 feet long and weighing about 58,000 pounds strewn about the site for crews to experiment with. A break room with two large refrigeration coolers to store beverages — hydration … [Read more...] about Hyperloop could revolutionize transport

Though the facility is normally used for satellite testing, the students employed its capabilities to see how the components set to be integrated … [Read more...] about SpaceX’s Hyperloop Competition Finalist Tests Pod Motor In ESA’s Space Simulator
Our in-box had a nice surprise tonight as one of our tipsters reported to us what is supposedly the specs for the Motorola X . We have seen so many different stories about this phone , with the most recent one calling the Motorola X a whole line of customizable phones that are build to customer specifications. This was somewhat confirmed last week by Motorola advisor Guy Kawasaki whose Google+ page showed a video for the customizable "Porsche Exclusive" with the sentence " Wouldn’t it be great if you could personalize your phone like this ?" Our tipster had no information about any sort of customizable phone. What he is telling us is that the Motorola X will have a 4.8 inch screen , made of sapphire glass, said to be three times harder to crack than Gorilla Glass . The corners will be made with rubber bumpers and the back will be made of carbon fiber. Under the hood will be a quad-core 2GHz Qualcomm Snapdragon 800 and a 4,000mAh battery provides all-day power. The … [Read more...] about Latest rumored Motorola X specs: 4.8 inch screen, Qualcomm Snapdragon 800, November launch

And this is the same thing like putting a full HD display on a phone running crap mediatek chipset. posted on 23 Mar 2014, 11:29 1 4. Dude2014 (Posts: 448; Member since: 12 Feb 2014) Those crap mediatek chipsets nowadays are much better than your Galaxy S2's antique fossil chipset even if they both run at your GS2's crap resolution. Just saying. :) posted on 23 Mar 2014, 11:38 4 7. alltechinside (Posts: 248; Member since: 21 Apr 2013) That antique fossil chipset was the leading chipset at the time... posted on 23 Mar 2014, 11:41 2 8. StraightEdgeNexus (Posts: 3689; Member since: 14 Feb 2014) Hehaheha whatever. I'm also an owner of nexus 7 2 now. Dont know why people heat over simple opinions. And in no way those crap mediatek chips are better than my exynos 4 gs2. It … [Read more...] about Comments for : Oppo Find 7: is the higher price worth the same performance?
