Quantum #teleportation theory to be tested on the #ISS - 8 views

  •  
    A theory-SuperDense quantum teleportation-posed by Hampshire College physics professor Herbert Bernstein will be tested on the International Space Station. Theoretical physicist Bernstein devised the SuperDense scheme more than a decade ago in his investigations of different ways to send a quantum state from one part of a laboratory to a remote station.

    Anna could you have a closer look into this - we should at least know what they are up to, be able to explain if anybody asks ... I also somehow missed this one in the NIAC study descriptions ... maybe a good moment to have another look at these "This is the second NASA grant for SuperDense quantum teleportation. A grant awarded in 2010 through NASA Innovative Advanced Concepts (NIAC) investigated the viability of the theory and produced the world's first experimental demonstration. Surprising or seminal experiments have marked Bernstein's research career. This is the fourth time a major proposal has become reality; two of his experiments helped found new sub-fields of physics (neutron interferometry and entanglement for quantum information)."

Probabilistic fluidic modular construction - 17 views

Looks cool... in simulation. And even there it seems to work terribly slow (note how much they have to speed it up).

  • “StarTiger is a fresh approach to space engineering,” explains Peter de Maagt, overseeing the project. “Take a highly qualified, well-motivated team, gather them at a single well-equipped site, then give them a fixed time to solve a challenging technical problem.”
  • StarTiger stands for ‘Space Technology Advancements by Resourceful, Targeted and Innovative Groups of Experts and Researchers’ working within the Agency’s TRP Basic Technology Research Programme. It brings team members together on a single site to work on a set challenge, aiming to produce a working prototype by the end of the project’s time limit.
  •  
    StarTiger: similar, yet different from the way the ACT does things. Seems like a very interesting programme.
  •  
    Nice initiative and also a good approach, problem-oriented within a fixed time frame. Could definitely be a highly motivating approach, similar to GTOC... I think the ACT should do this more often, targeted at future technologies and/or missions. The team could be structured around 'problems' instead of 'research areas', this will promote multidisciplinary work as well, plus it will also focus activities more. The problems, or more broadly concepts, are identified by the team and a few get chosen as main activities. Subsequent RF and YGT hiring is then done to strenghten the research team. These projects have a maximum lifetime maybe of 1 year? Thoughts?
  •  
    I'm impressed already by what an innovative group of experts and researchers was able to achieve when resourcefully targeted at coming up with the project's name...

    haha :) well.. don't shoot me Dario. I wasn't involved in this disclosure. But now that the link is public, you might all want to consider subscribing to their feed: http://ewds.strath.ac.uk/space/Podcasts.aspx They have some nice talks there. One of them is by Ken McLeod, the science fiction writer. Is anyone else with me on the idea that we should also invite science fiction writers for science coffees? :)
  •  
    So nice to hear Dario again! :-) But apparently UoS needs someone a bit more skilled to handle these videos...

    Only one self-comment alla Barney ..... suit-up

SPACE.com -- Railway to the Sky? NASA Ponders New Launch System - 3 views

  • A team of engineers from NASA's Kennedy Space Center in Florida and some of the agency's other field centers are looking into this and other novel launch systems based on cutting-edge technologies.
  • The launch system would require some advancements of existing technologies, but it wouldn't need any brand-new technologies to work
  • Scramjet vehicles could be used as a basis for a commercial launch program
  • ...1 more annotation...
  • It's not very often you get to work on a major technology revolution
  •  
    I wonder if they are also working with that SCRAMSPACE initiative in Australia that was presented at ESTEC a while back...
  •  
    what about a space elevator!!! quiet old concept (1895), see this link on wiki http://en.wikipedia.org/wiki/Space_elevator

    An interesting (free) journal on philosophy, with even some article with mathematics and physics !
  •  
    Reading the titles somehow reminds me of the most important webpage of the ACT: the Advanced Concepts Generator :-)

    once again one of these initiatives that came up from a situation and that would never have been possible with a top-down approach .... fantastic! and as Dario said: we are apparently where NASA still has to go with this :-)
  •  
    Actually, NASA Ames did that already within the NASA Open Source Agreement in 2008 for a V&V software!
  •  
    indeed ... you are right .... interesting project btw - they started in 1999, were in 2005 the first NASA project on Sourceforge and won several awards .... then this entry why they did not participate last year: "05/01/09: Skipping this years Google Summer-of-Code - many of you have asked why we are not participating in this years Summer of Code. The answer is that both John and Peter were too busy with other assignments to set this up in time. We will be back in 2010. At least we were able to compensate with a limited number of NASA internships to continue some of last years projects." .... but I could not find them in this years selected list - any clue?
  •  
    but in any case, according to the apple guru, Java is a dying technology, so their project might as well ...
  •  
    They participate under the name "The Java Pathfinder Team" (http://babelfish.arc.nasa.gov/trac/jpf/wiki/events/soc2010). It is actually a very useful project for both education and industry (Airbus created a consortium on model checking soft, and there is a lot of research on it) As far as I know, TAS had some plans of using Java onboard spacecrafts, 2 years ago. Not sure the industry is really sensible about Jobs' opinions ;) particularly if there is no better alternative!

  •  
    very nice selection of projects by NIAC!! there are at least some who have European partners as it looks like ... lets still see if we can get involved ...
  •  
    Interesting. Is it NASA's equivalent of ESA's GSP?
  •  
    It is a good thing NIAC is alive again. Wie, Bong -> "Optimal Dispersion of Near-Earth Objects" . I wonder what it is?

  • NASA should revive its Institute for Advanced Concepts, a blue-skies idea mill that closed in 2007, says an expert panel – but it says the new incarnation should have its feet a little closer to the ground.
  •  
    NASA should revive its own ACT, expert panel says.

Bio-Derived Porous Carbon Anodes for Li-ion Batteries #Nature - 3 views

  •  
    Here we explore the electrochemical performance of pyrolyzed skins from the species A. bisporus, also known as the Portobello mushroom, as free-standing, binder-free, and current collector-free Li-ion battery anodes. At temperatures above 900 °C, the biomass-derived carbon nanoribbon-like architectures undergo unique processes to become hierarchically porous. Basically they burned a Portobello mushroom and used it as a battery... now thats an multidisciplinary advanced concept

Quantum entanglement at ambient conditions in a macroscopic solid-state spin ensemble - 1 views

  •  
    Quoted from one of the authors in a separate interview: "We know that the spin states of atomic nuclei associated with semiconductor defects have excellent quantum properties at room temperature," said Awschalom, Liew Family Professor in Molecular Engineering and a senior scientist at Argonne National Laboratory. "They are coherent, long-lived and controllable with photonics and electronics. Given these quantum 'pieces,' creating entangled quantum states seemed like an attainable goal." Bringing the quantum world to the macroscopic scale could see some interesting applications in sensors, or generally entanglement-enhanced applications.
  •  
    They were previously working on the same concept in N-V centers in diamond (as a semiconductor). Here the advantage is that SiC could in principle be integrated with Si or Ge. Anyway its all about controlling coherence. In the next 10 years some breakthroughs are expected in the field of semiconductor spintronics, but quantum computing in this way lies still in the horizon

Black Hole Power: How String Theory Idea Could Lead to New Thermal-Energy Harvesting Te... - 0 views

  •  
    A new class of exotic materials could find its way into next-generation technologies that efficiently convert waste heat into electrical current according to new research. Both the exotic materials and the means by which they generate electricity rely on a hybrid of advanced concepts-including string theory combined with black holes combined with cutting-edge condensed matter physics.
