New Invention Generates Electricity "Out of Thin Air" - Offers Clean Energy 24/7 - 1 views

  •  
    Is this for real ?
  •  
    Very interesting, indeed! I wonder if it even can be beefed up. The devices produce a sustained voltage of around 0.5 volts across a 7-micrometre-thick film, with a current density of around 17 microamperes per square centimetre

    You were a bit faster than me! On top is the corresponding paper.

18-year-old massively improves supercapacitors during Intel International Science and E... - 1 views

    "Her goal was to design and synthesise a super capacitor with increased energy density while maintaining power density and long cycle life. She designed, synthesised and characterised a novel core-shell nanorod electrode with hydrogemated TiO2(H-TiO2) core and polyaniline shell. H-TiO2 acts as the double layer electrostatic core. Good conductivity of H-TiO2 combined with the high pseudo capacitance of polyaniline results in significantly higher overall capacitance and energy density while retaining good power density and cycle life. This new electrode was fabricated into a flexible solid-state device to light an LED to test it in a practical application. Khare then evaluated the structural and electrochemical properties of the new electrode. It demonstrated high capacitance of 203.3 mF/cm2 (238.5 F/g) compared to the next best alternative super capacitor in previous research of 80 F/g, due to the design of the core-shell structure. This resulted in excellent energy density of 20.1 Wh/kg, comparable to batteries, while maintaining a high power density of 20540 W/kg. It also demonstrated a much higher cycle life compared to batteries, with a low 32.5% capacitance loss over 10,000 cycles at a high scan rate of 200 mV/s."

    All Prior Art is a project attempting to algorithmically create and publicly publish all possible new prior art, thereby making the published concepts not patent-able. The concept is to democratize ideas, provide an impetus for change in the antiquated patent system, and to preempt patent trolls. The system works by pulling text from the entire database of US issued and published (un-approved) patents and creating prior art from the patent language. While most inventions generated will be nonsensical, the cost to computationally create and publish millions of ideas is nearly zero - which allows for a higher probability of possible valid prior art.

Occupy Federal Science: "Transformative" Research Can't Come From Milquetoast | The Cru... - 4 views

  •  
    I like this one "The kind of idle pastime that might amuse physicists is to imagine drafting Einstein's grant applications in 1905. "I propose to investigate the idea that light travels in little bits," one might say. "I will explore the possibility that time slows down as things speed up," goes another. Imagine what comments these would have elicited from reviewers for the German Science Funding Agency, had such a thing existed. Instead, Einstein just did the work anyway while drawing his wages as a technical expert third-class at the Bern patent office. And that is how he invented quantum physics and relativity." There is an even more pointer example of the Prussian academy of sciences reviewing the Dr. application of Hertz ...

    Shocking. What is federal research funding for? No, wrong question. Instead maybe: What is federally funded review for?

The World's Fair 2014 - Isaac Asimov's predictions 40 years ago - 3 views

  •  
    saac Asimov's predictions of the year 2014 back in 1964.. Truly amazing to read how close his sharp mind turned out to be at that time (cold war, Yuri Gagarin just went into space and Fortran first appeared 7 years before). The last prediction also came true I think, however the solution was not psychiatry.. instead we invented Facebook, Twitter and Instagram
  •  
    Also, he predicted that solar power stations would power the places on earth where solar power nor fission (?) would be available... Not there yet

Volvo Invents a Solar Panel That Unfurls From the Car Trunk - 2 views

    A 7x7x3m large unfolding structure from the car trunk. "Before the design is ready to roll, the team still needs to tune up the solar components, a challenge made more difficult by the pavilion's inherent mobility, making it impossible to gauge how sunlight will fall on it."

    Interesting to see that almost everything in sci-fi that looks pretty cool requires a power source that has not been invented yet. Imagine what would be possible if you would have a table top high power source available.

Cut EU red tape: Report from the Business Taskforce - 2 views

  •  
    some interesting recommendations part of a current discussion between the commission and some member states in a general, and apparently popular with all parties, drive to reduce bureaucracy to, among other things, stimulate innovation. Firms face a challenge. They produce superb products, offer world-class services and benefit from being able to sell to a European market of 500 million customers. But they are often encumbered by problematic, poorly-understood and burdensome European rules. The impact is clear: fewer inventions are patented, fewer sales are made, fewer goods are produced and fewer jobs are created.
  •  
    what hypocrites ... "As businesspeople, we are convinced that these and many other problems must be addressed if British and European firms are to compete in the global marketplace. We need regulation to operate in a pan-European market. We are not against regulation per se. But we need regulation that is pro-growth and pro-innovation." sure ....

DoD Buzz | Back Away from GPS: AF Chief - 4 views

  • develop alternatives to GPS
  • The fact that the U.S., which invented GPS and most of what depends on it (ATMs, gas pumps, trucking companies and lost spouses), would consider stepping away from the system marks a cultural and technological milestone
  • recommended that the U.S. scrap building five more GPS satellites and engage European allies on sharing their proposed Galileo global navigation satellite system

  •  
    Well, true - making data public is one thing, and making others to work through them for you is another... I love the new term "citizen science" though (and an explanation on the Wikipedia page why they had to invent a new one because "crowdsourcing" is soooooo - politically - wrong).

What the strange persistence of rockets can teach us about innovation. - 5 views

  •  
    If I could write, this is exactly what I would write about rocket, GO, and so on... :) "we are decadent and tired. But none of the bright young up-and-coming economies seem to be interested in anything besides aping what the United States and the USSR did years ago. We may, in other words, need to look beyond strictly U.S.-centric explanations for such failures of imagination and initiative. ... Those are places we need to go if we are not to end up as the Ottoman Empire of the 21st century, and yet in spite of all of the lip service that is paid to innovation in such areas, it frequently seems as though we are trapped in a collective stasis." "But those who do concern themselves with the formal regulation of "technology" might wish to worry less about possible negative effects of innovation and more about the damage being done to our environment and our prosperity by the mid-20th-century technologies that no sane and responsible person would propose today, but in which we remain trapped by mysterious and ineffable forces."

    Very interesting, though I'm amused how the author tends to (subconsciously?) shift the blame to non-US dictators :-) Suggestion that in absence of cold war US might have abandoned HB and ICBM programmes is ridiculous.
  •  
    Interesting, this was written by Neal Stephenson ( http://en.wikipedia.org/wiki/Neal_Stephenson#Works ). Great article indeed. The videos of the event from which this arose might be equally interesting: Here Be Dragons: Governing a Technologically Uncertain Future http://newamerica.net/events/2011/here_be_dragons "To employ a commonly used metaphor, our current proficiency in rocket-building is the result of a hill-climbing approach; we started at one place on the technological landscape-which must be considered a random pick, given that it was chosen for dubious reasons by a maniac-and climbed the hill from there, looking for small steps that could be taken to increase the size and efficiency of the device."
  •  
    You know Luis, when I read this quote, I could help thinking about GO, which would be kind of ironic considering the context but not far from what happens in the field :p
  •  
    Fantastic!!!
  •  
    Would have been nice if it were historically more accurate and less polemic / superficial
  •  
    mmmh... the wheel is also an old invention... there is an idea behind but this article is not very deepfull, and I really don't think the problem is with innovation and lack of creative young people !!! look at what is done in the financial sector...

William Shatner Wakes Up Crew for Final Discovery Mission - Slashdot - 1 views

  • The Space Shuttle Discovery left the International Space Station this morning for the last time. To commemorate the ship's accomplishments over 27 years of service, the crew was greeted to a morning wake-up message from Capt. Kirk. "Space, the final frontier," Shatner said in a prerecorded message. "These have been the voyages of the space shuttle Discovery. Her 30-year mission: to seek out new science, to build new outposts, to bring nations together on the final frontier, to boldly go and do what no spacecraft has done before."

    here's a recording of the transmission: http://ia600406.us.archive.org/13/items/STS-133/03-07-11_STS-133_FD12_Crew_Wakeup.mp3 to quote from the thread at reddit: "When the space shuttle first flew, 55 americans were being held hostage in the embassy in Iran, and Ronald Reagan had just become president. That same year Prince Charles would marry Lady Diana, the HIV virus would be first identified, Post-It notes were invented, and a small company called Microsoft released it's new operating system MS-DOS."
