Mitos y verdades en torno al mercado del litio | Chile Desarrollo Sustentable El mineral ha estado en el centro de la noticia, tras la decisión del gobierno de abrir su explotación a empresas públicas y privadas. Los expertos aterrizan el debate. Los satélites, las naves espaciales, los celulares, los computadores portátiles, los marcapasos, las cámaras digitales, los vehículos eléctricos y los medicamentos antidepresivos. Todos estos elementos tienen algo en común: el litio, un metal blando de color blanco plateado, que posee una gran capacidad para almacenar energía. Hoy, este mineral está en el centro de la noticia, tras la decisión del gobierno de abrir su explotación a empresas públicas y privadas, proceso que hoy interesa a Codelco. Actualmente, en Chile sólo dos compañías producen litio: SQM y SCL (Chemetall). En medio del debate generado en torno al tema se han tejido distintas conjeturas sobre su importancia, perspectivas de precio y disponibilidad a nivel mundial. “Oro blanco o petróleo blanco”. Juan Carlos Guajardo, de Cesco, aporta otro elemento.
An Interview with Jacques Piccard, 1922-2008 [Photo via AP] I'm saddened to read that Jacques Piccard died today. Jacques Piccard was a Swiss oceanic engineer famous for making the deepest ever ocean dive, which he accomplished on January 23, 1960 along with Lt. Don Walsh. I had the good fortune to interview Mr. Please read and enjoy it. Interview with Jacques Piccard Okay, yeah, sure Okay, please you will excuse me but my English is relatively poor. Our base was in . And until we could arrive to the place, precise place of the Mariana Trench where we were to descend, to dive, we had about four days to tow the submarine with a tugboat and the sea was pretty rough, and it was not a very nice trip. And when we arrived on the 23rd of January [1960], the early morning, we arrived at the place, we had to start the dive as soon as possible because the waves were bad and the sea was very rough, windy, some rain also I believe, and so on. But the blue of the light was absolutely beautiful, clear and limpid and absolutely beautiful water. Why?
Little reactors may be best path to nuclear fusion - tech - 05 November 2014 IT ALWAYS seems to be 30 years away. Controlled nuclear fusion seems no closer to being realised now than it was when the idea was put forward in the 1950s. But fusion power stations might be closer than anyone suspected – if we think small. Bigger is better, or so goes the accepted wisdom with nuclear fusion. The massive international experiment ITER takes this to the extreme, employing a doughnut-shaped reaction chamber 20 metres across and up to 1000 staff. The price tag? Now some are advocating that a smaller-scale approach could be swifter and cheaper. Fusion reactors promise cheap, clean energy, leaving behind only small amounts of radioactive waste and with little risk of runaway meltdowns. It is easier said than done. A major challenge is how to hold the chaotic plasma in place for more than the tiniest fraction of a second. Which design wins out may come down to funding.

La mitad de los automóviles nuevos serán eléctricos en 2020 Las baterías de litio-ion son una de las principales esperanzas para un mayor desarrollo de los vehículos híbridos y eléctricos. Imagen: medioambienteok.blogspot.com De acuerdo a una investigación encarada por especialistas de la Universidad de Duke, Estados Unidos se encuentra en una posición ventajosa como para transformarse próximamente en líder mundial en el campo de las baterías de litio-ion para coches eléctricos, considerando los distintos avances tecnológicos registrados. En consecuencia, podría aproximarse al nivel asiático, mercado que actualmente lidera este segmento. Asimismo, sobre 2020 se lograría que el 50% de los vehículos nuevos adquiridos en Estados Unidos utilicen una tecnología de propulsión híbrida o eléctrica.

Programmable Matter: Claytronics or Gershenfeld We still tell our children “you can be anything when you grow up.” It’s time to start telling them “you’re going to be able to make anything…right now.” Similar work at MIT and Carnegie Mellon is pointing towards the next revolution in computers and manufacturing: programmable matter. In the future you won’t use computers to design a car, the car will form from billions of tiny computers that arrange themselves into anything you want. The physical and computational world will merge. Claytronics is developing tiny computers that can work together to form shapes. How can a material be intelligent? Carnegie Mellon isn’t the only university pursuing intelligent materials. It All Looks Good on Paper It would be amazing if these technologies were available today, but they are still a long way off. In hardware, Claytronics has already made centimeter sized cylindrical catoms that have basic features. To test Catom forces without gravity, helium filled prototypes are used.
Longer distance quantum teleportation achieved Physicists at the University of Geneva have succeeded in teleporting the quantum state of a photon to a crystal over 25 kilometers of optical fiber. The experiment, carried out in the laboratory of Professor Nicolas Gisin, constitutes a first, and simply pulverises the previous record of 6 kilometres achieved ten years ago by the same UNIGE team. Passing from light into matter, using teleportation of a photon to a crystal, shows that, in quantum physics, it is not the composition of a particle which is important, but rather its state, since this can exist and persist outside such extreme differences as those which distinguish light from matter. Quantum physics, and with it the UNIGE, is again being talked about around the world with the Marcel Benoist Prize for 2014 being awarded to Professor Nicolas Gisin, and the publication of experiments in Nature Photonics.

Atomenergoprom Study: U.S. challenging Asia in advanced batteries race (PhysOrg.com) -- In the global race to develop and produce advanced lithium-ion batteries for these electric vehicles, the United States is well-positioned to be a worldwide leader. By 2020, more than half of new vehicle sales are expected to be hybrid-electric, plug-in hybrid and all-electric models. In the global race to develop and produce advanced lithium-ion batteries for these electric vehicles, the United States is well-positioned to be a worldwide leader, a new Duke University study finds. When hybrids first appeared, Japan beat the United States by about 10 years with its Toyota Prius, the report by researchers at Duke's Center for Globalization, Governance & Competitiveness notes. Marcy Lowe, lead author of the report, notes that nearly all lithium-ion batteries for cell phones and laptops today are made in Asia, even though a University of Texas professor helped develop the technology in the 1980s.

Readings - Bohmian-Mechanics.net This is part of a correspondence between Sheldon Goldstein and Steven Weinberg on Bohmian Mechanics. It is published here with the kind permission of both. From: oldstein@fermat.rutgers.edu To: WEINBERG@utaphy.ph.utexas.edu Subject: NYRB Date: Sun, Sep 22 1996, 17:14:44 Dear Professor Weinberg, In your recent response in the NYRB, you ask George Levine, my colleague here at Rutgers, to "suppose that physicists were to announce the discovery that, beneath the apparently quantum mechanical appearance of atoms, there lies a more fundamental substructure of fields and particles that behave according to the rules of plain old classical mechanics." I agree with your point that this should make little difference to our views about culture or philosophy. Best, Shelly Goldstein From: WEINBERG@physics.utexas.edu To: oldstein@fermat.rutgers.edu Subject: Bohm's quantum mechanics Date: Tue, 24 Sep 1996, 21:01:39 -0500 (CDT) Dear Professor Oldstein, I have carried out the experiment you requested.
