Startup turns carbon dioxide into fuels - 1 views

  • Today, carbon dioxide (CO2) is a hot topic. Scientists around the globe are searching for ways to store, dispose of, or prevent the formation of the greenhouse gas, which is a major driver of global climate change. Liquid Light hopes to take this concept one step further and harness waste CO2 as a source of carbon to make industrial chemicals and fuels.
  • Take CO2 and mix it in a water-filled chamber with an electrode and a catalyst. The ensuing chemical reaction converts CO2 into a new molecule, methanol, which can be used as a fuel, an industrial solvent or a starting material for the manufacture of other chemicals.
  • Bocarsly likes to call the process "reverse combustion" because it is like running a burning reaction backwards. Instead of burning fuel and oxygen to produce CO2, the CO2 converts back into fuel and oxygen.

  • Cole set up a flask containing a solution of CO2 and a pyridinium catalyst dissolved in water. In place of sunlight, which emits a broad spectrum of wavelengths of light, she shined on the flask a blue light-emitting diode (LED) because it gives off certain wavelengths that are highly efficient at driving the reaction. In the flask she placed an electrode that is activated by particles of light, or photons. "We used a semiconductor electrode that would allow us to substitute light for electricity," said Cole.
  • The Princeton scientists did some additional studies, and made a surprising discovery: They could turn CO2, which contains only one carbon, into a compound with a carbon-carbon bond, which vastly increases the possibilities for creating commercial applications.

Why Does College Cost So Much--And Why Do So Many Pundits Get It Wrong? | HASTAC - 28 views

  •  
    "To say that American universities are too expensive is like saying cars are too expensive. What do we mean by such a statement?  Are we talking about the cost of a Lamborghini Veneno (at 3.5M, one of the world's  most expensive cars) or a Hyundai Atos (at $9000, one of the least expensive)?  For the captain of industry, the sultan, or the magnate, there might not be enough luxury features on the Lamborghini.  For the person barely hanging on to that minimum wage job with no benefits, paying $9000 for an Atos to get across town to work at Walmart every day may be hopelessly out of reach.   "

    on the revolutionary aspect of MOOCs to break down traditional barriers to higher ed as regularly stated by CEOs Koller and Thrun: "This rhetoric is perhaps the most glittery yet in the public discourse about online higher education. But it is also a diversion shifting attention away from the logic of profit-making. For parents, students, and the general public who focus primarily on what education means for people's futures, for social mobility, for a healthy economy and a robust democracy, a dip into the insider talk of MOOCs, their investors, and industry analysts is both instructive and disorienting."

AASA :: Public School Bashing: A Dangerous Game - 58 views

  •  
    One of the best articles that I have read on change, reform, school bashing, Waiting for Superman,...
  •  
    Really liked this! I sent it to all my teacher friends. She does a good job addressing a much better way to enact change in our districts than the method used by media and Hollywood. I think Waiting for Superman is a cop-out. A bonafide cop-out. It's so easy for the media and entertainment industry to just throw sticky-bombs at public schools. The ironic thing is there are so many privileged individuals in the media industries that were taught in elitist environments. When is someone going to make a movie bashing parents who do nothing to help their children succeed? Lastly, I loved her comment about the decision being dumber the further the person making is from a real classroom. Classic. Thanks again for sharing.
  •  
    Glad you found it helpful. I thought it was very clear, well written, and offers some solutions... solutions that require social and moral change, not just political and hegemonic change.

The Wealth of Networks » Chapter 1: Introduction: A Moment of Opportunity and Challenge - 0 views

  •  
    Yochai Benkler's wealth of nations book online Next Chapter: Part I: The Networked Information Economy » read paragraph Chapter 1: Introduction: A Moment of Opportunity and Challenge 1 Information, knowledge, and culture are central to human freedom and human development. How they are produced and exchanged in our society critically affects the way we see the state of the world as it is and might be; who decides these questions; and how we, as societies and polities, come to understand what can and ought to be done. For more than 150 years, modern complex democracies have depended in large measure on an industrial information economy for these basic functions. In the past decade and a half, we have begun to see a radical change in the organization of information production. Enabled by technological change, we are beginning to see a series of economic, social, and cultural adaptations that make possible a radical transformation of how we make the information environment we occupy as autonomous individuals, citizens, and members of cultural and social groups. It seems passé today to speak of "the Internet revolution." In some academic circles, it is positively naïve. But it should not be. The change brought about by the networked information environment is deep. It is structural. It goes to the very foundations of how liberal markets and liberal democracies have coevolved for almost two centuries.

Edu-Traitor! Confessions of a Prof Who Believes Higher Ed Isn't the Only Goal | HASTAC - 52 views

  • many brilliant, talented young people are dropping out of high school because they see high school as implicilty "college prep" and they cannot imagine anything more dreary than spending four more years bored in a classroom when they could be out actually experiencing and perfecting their skills in the trades, the skills, and the careers that inspire them.
  • The abolishing of art, music, physical education, tech training, and shop from grade schools and high schools means that the requirement for excellence has shrunk more and more right at the time when creativity, imagination, dexterity, adaptability to change, technical know-how, and all the rest require more not less diversity.

  • There are so many viable and important and skilled professions that cannot be outsourced to either an exploitative Third World sweat shop or to a computer, that require face-to-face presence, and a bucketload of skills--but that  do not require a college education:  the full range of IT workers, web designers, body workers (ie deep tissue massage), yoga and pilates instructors, fitness educators, DJ's, hair dressers, retail workers, food industry professionals, entertainers,  entertainment industry professionals, construction workers, dancers, artists, musicians, entrepreneurs, landscapers, nanny's, elder-care professionals, nurses's aids, dog trainers, cosmetologists, athletes, sales people, fashion designers, novelists, poets, furniture makers, book keepers, sound engineers, inn keepers, wedding planners, stylists, photographers, auto mechanics, and on and on.

    In general, I agree. However, novelists and poets don't need college?? And perhaps less so to artists and musicians? Perhaps... but what better way to learn the history and analysis of their Art, in order to place their own work in context?
  •  
    I could not agree more with you Maureen. As a long time middle school teacher in Oakland and Mpls I am thoroughly convinced that our nation and our states are nuts to have cut all of the tech and arts classes out of elementary, middle and high schools. EVERY student should learn a trade/skill set in high school. The hs drop out rate is horrifying and no surprise that the crime rate follows. We have a nation of under achieving teens because the adults have not kept up with funding the myriad of opportunities that would capture and harness their interests and creativity. I look forward to reading your book Maureen and to following you on here.

PopTech 2009: Michael Pollan on "sustainable food" - 30 views

  •  
    Author and activist Michael Pollan is a passionate advocate for sustainable food. In his compelling talk at PopTech, he explores how our industrial food system is keeping us overly dependent on fossil fuels, destroying our environment, and making us sick. Breaking this cycle requires fundamentally changing our relationship to food - and eating more meals together. - awesome!

Noam Chomsky on Democracy and Education in the 21st Century and Beyond - 38 views

  • So a lot of public education was, in fact, concerned with trying to teach independent people to become workers in an industrial system.
  • we have to train them in obedience and servility, so they're not going to think through the way the world works and come after our throats.
  • One can at least be suspicious that skyrocketing student debt is a device of indoctrination

  • It's not just you learned how a mosquito flies in the rain, but you learn how to be creative and why it's exciting to learn things and create things and make up new things. And that can be done from kindergarten on
  • There are a lot of factors. And one of them, probably, is just that students are trapped
  • First of all, the existence of the advertising industry is a sign of the unwillingness to let markets function. If you had markets, you wouldn't have advertising. Like, if somebody has something to sell, they say what it is and you buy it if you want. But when you have oligopolies, they want to stop price wars
  • there's no real economic reason for high-priced higher education and skyrocketing student debt
  • It doesn't matter how much you learn in school; it's whether you learn how to go on and do things by yourself
