    The supply of secure, clean, sustainable energy is arguably the most important scientific and technical challenge facing humanity in the 21st century. Rising living standards of a growing world population will cause global energy consumption to double by mid-century and triple by the end of the century. Even in light of unprecedented conservation, the additional energy needed is simply not attainable from long discussed sources these include nuclear, biomass, wind, geothermal and hydroelectric. The global appetite for energy is simply too much. Petroleum-based fuel sources (i.e., coal, oil and gas) could be increased. However, deleterious consequences resulting from external drivers of economy, the environment, and global security dictate that this energy need be met by renewable and sustainable sources. The dramatic increase in global energy need is driven by 3 billion low-energy users in the non-legacy world and by 3 billion people yet to inhabit the planet over the next half century. The capture and storage of solar energy at the individual level personalized solar energy drives inextricably towards the heart of this energy challenge by addressing the triumvirate of secure, carbon neutral and plentiful energy. This talk will place the scale of the global energy issue in perspective and then discuss how personalized energy (especially for the non-legacy world) can provide a path to a solution to the global energy challenge. Daniel G. Nocera is the Henry Dreyfus Professor of Energy at the Massachusetts Institute of Technology, Director of the Solar Revolutions Project and Director of the Eni Solar Frontiers Center at MIT. His group pioneered studies of the basic mechanisms of energy conversion in biology and chemistry. He has recently accomplished a solar fuels process that captures many of the elements of photosynthesis outside of the leaf. This discovery sets the stage for a storage mechanism for the large scale, distributed, deployment of solar energy. He has b

    "The report  gets across one very basic message: in the eyes of the leading experts on aerospace technology worldwide: harvesting solar power in space and transmitting it to earth is no longer science fiction," says author Howard Bloom in a companion announcement by the Space Development Steering Committee. "It is sound, current-technology-based science fact.  And it is a green energy option we can't ignore.

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.

US approves world's biggest solar energy project in California | KurzweilAI - 0 views

  •  
    The U.S. Department of Interior approved on Monday a permit for Solar Millennium, LLC to build the largest solar energy project in the world - four  plants at the cost of one billion dollars each - in southern California. The project is expected to generate up to 1,000 Megawatts of energy, enough electricity to annually power more than 300,000 single-family homes, more than doubling the solar electricity production capacity of the U.S. Once constructed, the Blythe facility will reduce CO2 emissions by nearly one million short tons per year, or the equivalent of removing more than 145,000 cars from the road. Additionally, because the facility is "dry-cooled," it will use 90 percent less water than a traditional "wet-cooled" solar facility of this size. The Blythe facility will also help California take a major step toward achieving its goal of having one third of the state's power come from renewable sources by the year 2020. The entire Blythe Solar Power Project will generate a total of more than 7,500 jobs, including 1,000 direct jobs during the construction period, and thousands of additional indirect jobs in the community and throughout the supply chain. When the 1,000 MW facility is fully operational it will create more than 220 permanent jobs. Adapted from materials provided by Solar Millennium, LLC.

Brazil Outpaces All Other Countries in Reducing Global Warming Emissions - 0 views

  •  
    "Brazil has done more than any other country over the past five years to cut global warming emissions by dramatically reducing its deforestation. Destroying tropical forests is responsible for about 15 percent of global warming pollution, and Brazil had been the biggest source of deforestation pollution. Its reduction is a stunning turnaround.

Humanity Needs to Keep Pace with Technology (cont'd) | The Veracious Blog - 0 views

    When we talk about participation, we have to be a bit more specific. On the publishing side, there's clearly more participation than we've ever seen in the past. But in order for this tidal wave of information to be useful, we need to be able to separate fact from fiction. We need to encourage participation on the receiving end. What we need is evaluating participation. With the breadth of niche information and sources we have the ability to get at the best of what is known on a myriad of topics and contexts. Every niche has its experts and its hacks, its enthusiasts and detractors. But for the remaining 95% of us who are not subject matter experts, deriving the accurate or useful information from the sea of what is available can be complicated, time-consuming and simply unverifiable. We need a way to quantify the value of information, or more specifically, the veracity of information.

    Low-Cost Multi-point Interactive Whiteboards Using the Wiimote Since the Wiimote can track sources of infrared (IR) light, you can track pens that have an IR led in the tip. By pointing a wiimote at a projection screen or LCD display, you can create very low-cost interactive whiteboards or tablet displays. Since the Wiimote can track upto 4 points, up to 4 pens can be used. It also works great with rear-projected displays.

  •  
    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.

Amateur Science and the Rise of Big Science | Citizen Scientists League - 0 views

  • Several trends came together to increase the professional nature of scientific work. First was the increasing cost of scientific work and its complexity. Scientific equipment became more precise and expensive. Telescopes, like those by Herschel, became bigger and bigger. Also, the amount of knowledge one needed to gain to contribute became increasingly daunting.
  • Second, the universities changed. Pioneered by the German states, which at the beginning of the 19th century was dismissed as a scientific backwater, universities began offering focused majors which trained students in a specific discipline rather than classical education as a whole. This was pioneered by Wilhelm von Humboldt, brother of the famous scientist Alexander von Humboldt, who was the Prussian Minister of Education.
  • Germany, once united, also provided impetus to two other trends that accelerated their dominance of science and the decline of amateurs. First, was the beginning of large-scale state sponsorship of science through grants which were first facilitated through the Kaiser Wilhelm Institute (now the Max Planck Institute). This eventually supplanted prizes as the dominant large-scale source of scientific funding. Countries like France that relied on prizes began to fall behind. Second, was the intimate cooperation between industrial firms like BASF and universities.

  • he final nail in the coffin was undoubtedly the Second World War. The massive mobilization of scientific resources needed to win and the discovery of war-winning inventions such as the atomic bomb and self-correcting bomb sight (with help from Norbert Wiener of MIT) convinced the nations of the world that the future was in large-scale funding and support of science as a continuous effort. Vannevar Bush, former president of MIT, and others pioneered the National Science Foundation and the military also invested heavily in its own research centers. Industrial labs such as those from Bell Labs, GE, Kodak, and others began dominating research as well. Interestingly, the first military investment in semiconductors coupled with research from Bell Labs led to what is now known as Silicon Valley.
