New solar energy conversion process could double solar efficiency of solar cells - 0 views

  •  
    A new process that simultaneously combines the light and heat of solar radiation to generate electricity could offer more than double the efficiency of existing solar cell technology, say the engineers who discovered it and proved that it works. The process, called 'photon enhanced thermionic emission," or PETE, could reduce the costs of solar energy production enough for it to compete with oil as an energy source.

Lasers could power drones in flight or launch rockets | KurzweilAI - 0 views

  •  
    Researchers at LaserMotive have devised a way to beam lasers to power military bases and drones, possibly helping to save lives, since delivering fuel to battle zones can be a dangerous task in wartime. Although still largely in the R&D stage, laser power beaming has many other potential uses, which include powering vehicles, replacing electric power wiring and transmission lines in difficult places, and even launching rockets into orbit. The beam is about 8 inches wide as it leaves the transmitter - and then spreads wider as it travels. The beam emitter is located at a ground-based unit and operated by a person, who could control it from the same location or remotely from an entirely different place altogether. The operator uses the machine to fire the laser beam at a photovoltaic collector located on an unmanned autonomous vehicle (UAV), small plane, or helicopter. The current range of the system is about a kilometer. When the laser hits the photovoltaic device, the photons in the light beam are converted to electricity to fly the AUV.

Researchers create self-assembling nanodevices that move and change shape on demand | K... - 0 views

  •  
    Harvard researchers have created nanodevices made of DNA that self-assemble and can be programmed to move and change shape on demand. The nanodevice structure is based on the principle of tensegrity: its strength and stability results from the way it distributes and balances the counteracting forces of tension and compression. This new technology could lead to nanoscale medical devices and drug delivery systems, such as virus mimics that introduce drugs directly into diseased cells. Or it could one day be used to reprogram human stem cells to regenerate different kinds of injured organs and tissue.

New system could make censorship of Internet sites virtually impossible - 0 views

  •  
    Chinese citizens could once again enjoy LOL Cats on YouTube - as well as content critical of the communist government - if a new system developed by researchers at the University of Michigan (U-M) and the University of Waterloo (UW) in Canada were implemented. The researchers claim the system, called Telex, would thwart Internet censorship and make it virtually impossible for a censoring government to block individual sites by essentially turning the entire web into a proxy server.

    If NASA ever gets a clear directive for interplanetary exploration, a new Hundred-Year Starship could be their version of the Mayflower. And like the first pilgrims, Martian explorers might set sail with the knowledge they would never return home.

Contrary Brin: Could Our Universe Be a Fake? - 0 views

  •  
    And now comes an era when we live immersed in computer-generated "virtual" realities, rendered through lavish games where ersatz selves get to do countless things that our mundane, fleshy selves cannot. Is it any wonder that some people have been talking about a near future when this process may reach its ultimate conclusion? When the denizens of Reality will not be able to verify, by any clear-cut means, that they aren't living in-or even existing because of-a simulation?

New laser technology could revolutionize communications | KurzweilAI - 0 views

  •  
    Engineers at Stevens Institute of Technology have developed a technique to optically modulate the frequency of a laser beam and create a signal that is disrupted significantly less by environmental factors, says Dr. Rainer Martini. The research provides for enhanced optical communications, allowing mobile units not tied to fiber optic cable to communicate in the range of 100 GHz and beyond, the equivalent of 100 gigabytes of data per second. Eventually, the team hopes to extend the reach into the terahertz spectrum. The frequency or amplitude modulation of middle infrared quantum cascade lasers has been limited by electronics, which are barely capable of accepting frequencies of up to 10 GHz by switching a signal on and off.  Marini and his team have developed a method to optically induce fast amplitude modulation in a quantum cascade laser to control the laser's intensity. Their amplitude modulation system employed a second laser to modulate the amplitude of the middle infrared laser, using light to control light. The current detector is only capable of detecting frequencies up to 10 GHz, but Dr. Martini is confident that a new detector will make the system capable of much higher frequencies. With an optical system that is stable enough, satellites may one day convert to laser technology, resulting in a more mobile military and super-sensitive scanners, as well as faster Internet for the masses, says Martini.

3-D avatars could put you in two places at once | KurzweilAI - 0 views

  •  
    Source: New York Times - Apr 11, 2011 In their new book, Infinite Reality, Dr. Jim Blascovich and Dr. Jerry Bailenson insist that 3-D conferences with avatars are nigh because consumer technology has suddenly caught up with the work going on in virtual-reality laboratories in academia. These psychologists point to three developments in the past year: the Microsoft Kinect tracking system for the Xbox, the Nintendo 3DS gaming device, and the triumph on "Jeopardy!" of IBM's Watson computer.

Sociology and History: Shapin on the Merton Thesis « Ether Wave Propaganda - 1 views

  • Shapin observed that the link Merton drew between Puritanism and seventeenth-century English science was a matter of happenstance rather than determinism. According to Merton, science requires certain “values” and “sentiments” allowing intellectual individualism, and fostering not only an interest in the transcendent, but also secular improvement. It so happened that these values and sentiments were to be found in Puritan asceticism and sense of social obligation, which thus provided a social context in which science could develop. Definitively, this was not to say that Puritanism provided a unique source of these values and sentiments, or that science did not have other roots. It was obviously possible for science to develop in Catholic contexts as well, despite the less hospitable value system of Catholicism. The confluence of values simply seemed to promise some insight into the growth of science in a particular time and place.
  • Robert K. Merton’s “functionalist” sociology viewed “science” as a kind of Weberian ideal type — a form of thought that is identifiable by its peculiar, philosophically-defined characteristics. Merton’s sociology of science held that this thought could also be identified with social behaviors, characterized by a set of “norms”, which made the thought possible. The Merton Thesis (which slightly predates Merton’s enumeration of science’s norms) holds that the rise of science in early-modern England could be linked to the social behaviors valued by the Puritanism of that milieu. This was the subject of Merton’s PhD thesis and his 1938 book Science, Technology and Society in Seventeenth-Century England.

Microsoft offers a glimpse into the future of productivity | KurzweilAI - 1 views

  •  
    Microsoft has posted an awesome new concept video with some ubercool new interfaces that could be here in five to ten years, estimates Kurt DelBene, President, Microsoft Office Division. That sounds a bit conservative. "All of the ideas in the video are based on real technology," he said. "Some of the capabilities, such as speech recognition, real time collaboration, and data visualization, already exist today. Others are not yet available in specific products, but represent active research and development happening at Microsoft and other companies." "Other companies" … hmm, some of the concepts look a bit like Nokia's visionary Morph concept tech  (see the video at the bottom of this post and our 2010 news item).
