By 2025, a leaner, smarter, more lethal, and flexible Army must operate differently, enable forces differently, and organize differently to maintain overmatch, capable of responding to a myriad of threats to our nation’s national interests, and to set the conditions for fundamental long-term change. To determine the optimal design for the Army of the future, …
A first automated reel-to-reel fluidic self-assembly process for macroelectronic applications is reported. This system enables high speed assembly of semiconductor dies (15,000 chips per hour using a 2.5 cm wide web) over large area substrates. The optimization of the system (hour 99% assembly yield) is based on identification, calculation, and optimization of the relevant forces. …
UCLA researchers were able to demonstrate that using multiferroic material to generate spin waves could reduce wasted heat and therefore increase power efficiency for computer processing by up to 1,000 times. Multiferroic magnetic materials reduce the amount of power consumed by “logic devices,” a type of circuit on a computer chip dedicated to performing functions …
Here is a mockup of the engine for the SR72 mach 6 spyplane which could have a flying prototype by 2018. If you liked this article, please give it a quick review on ycombinator or StumbleUpon. Thanks Brian WangBrian Wang is a Futurist Thought Leader and a popular Science blogger with 1 million readers per …
The SR-71 Blackbird was retired from U.S. Air Force service almost two decades ago, the perennial question has been: Will it ever be succeeded by a new-generation, higher-speed aircraft and, if so, when? Hypersonic flights tests were way more successful than advertised Skunk Works has been working with Aerojet Rocketdyne for the past seven years …
The first Starship Congress conference session was devoted to solar sails, leading off with Jim Benford’s keynote, followed by Les Johnson, who described current and near-term work. Right now the only propulsion method that will get us to interstellar velocities is the sail, and even then we’re talking no more than a couple of hundred …
The opening of a new high-speed train line linking Nanjing, Jiangsu province, with Ningbo, Zhejiang’s only deepwater port, will not only make the integration of the Yangtze River Delta region (population 75 million) almost a certainty. The new high-speed rail line passing through Hangzhou, Zhejiang’s provincial capital, will commence operations on Monday. Formerly, it took …
1. Digg reader seems to have a user interface that is more like the Google reader immediately after it imports the Google reader settings. 2. Feedly has some easy configurations to allow for organization by subscription and several other views such as magazine style. 3. The old reader requires that you get the subscription.xml file. …
There is a High Voltage DC supergrid technology roadmap. (107 pages. Mar 2013.) Direct Current becomes more cost effective at longer distances versus alternating current. At similar voltage level, a DC line can transmit more than double the power at about half the losses compared to an AC line for a 1000 kilometer line. Phases …
Big news in the search for dark matter may be coming in about two weeks when the first paper of results from the Alpha Magnetic Spectrometer, a particle collector mounted on the outside of the International Space Station, will be submitted to a scientific journal, said MIT physicist Samuel Ting, AMS principle investigator. It will …
A new World Bank-commissioned report warns the world is on track to a “4°C world” marked by extreme heat-waves and life-threatening sea level rise. The report is over 70 pages long. The global community has committed itself to holding warming below 2°C to prevent “dangerous” climate change, the sum total of current policies—in place and …
