    Pseudogap Theory Puts Physicists Closer To High Temperature Superconductors

    Physicists are one step closer to developing the world's first room-temperature superconductor thanks to a new theory from the University of Waterloo, Harvard and Perimeter Institute.

    The theory explains the transition phase to superconductivity, or "pseudogap" phase, which is one of the last obstacles to developing the next generation of superconductors and one of the major unsolved problems of theoretical condensed matter physics.

    Their work was published in this week's issue of the prestigious journal Science.

    Superconductivity is the phenomenon where electricity flows with no resistance and no energy loss. Most materials need to be cooled to ultra-low temperatures with liquid helium in order to achieve a superconductive state.

    The team includes Professor Roger Melko, Professor David Hawthorn and doctoral student Lauren Hayward from Waterloo's Physics and Astronomy Department, and Harvard Physics Professor Subir Sachev. Roger Melko also holds a Canada Research Chair in Computational Quantum Many-Body Physics.

    "This amazing scientific collaboration actually came about by chance over lunch at the Perimeter Institute between Subir and myself," said Hawthorn.

    Hawthorn showed Sachdev his latest experimental data on a superconducting material made of Copper and the elements Yttrium and Barium. The material, YBa2Cu3O6+x, had an unexplained temperature dependence. Sachdev had a theory but needed expert help with the complex set of calculations to prove it. That's where Melko and Hayward stepped in and developed the computer code to solve Sachdev's equations.

    Melko and Sachdev already knew each other through Perimeter Institute, where Melko is an associate faculty member and Sachdev is a Distinguished Research Visiting Chair.

    "The results all came together in a matter of weeks," said Melko. "It really speaks to the synergy we have between Waterloo and Perimeter Institute."

    To understand why room-temperature superconductivity has remained so elusive, physicists have turned their sights to the phase that occurs just before superconductivity takes over: the mysterious "pseudogap" phase.

    "Understanding the pseudogap is as important as understanding superconductivity itself," said Melko.

    The cuprate, YBa2Cu3O6+x, is one of the few materials known to be superconductive at higher temperatures, but scientists are so far unable to achieve superconductivity in this material above -179°C. This new study found that YBa2Cu3O6+x oscillates between two quantum states during the pseudogap, one of which involves charge-density wave fluctuations. These periodic fluctuations in the distribution of the electrical charges are what destabilize the superconducting state above the critical temperature.

    Once the material is cooled below the critical temperature, the strength of these fluctuations falls and the superconductivity state takes over.

    Superconducting magnets are currently used in MRI machines and complex particle accelerators, but the cost of cooling materials using Helium makes them very expensive. Materials that achieve superconductivity at a higher temperature could unlock the technology for new smart power grids and advanced power storage units.

    The group plans to extend their work both theoretically and experimentally to understand more about the fundamental nature of cuprates.

    See Ultraconductors at www.chavaenergy.com for polymer equivalents of room temperature superconductors.

    These proprietary materials function to 200 degrees C.

    They have been the subject of four successful Small Business Innovation Research contracts including a Phase II with the USAF.

    Almost 1,000 samples were independently fabricated for the Air Force.

    The materials are presently thin films with 1 micron conducting regions through the film carrying 50 Amperes.

    Tape wire and cable are on the horizon.

    Mark Goldes' "AESOP Institute" is simply an elaborate fraud.

    Mark Goldes, starting in the mid-seventies, engaged for several years in the pretense that his company SunWind Ltd was developing a nearly production-ready, freeway-capable, wind-powered "windmobile," based on the windmobile created by James Amick; and that therefore SunWind would be a wonderful investment opportunity.

    After SunWind "dried up" in 1983, Goldes embarked on the long-running pretense that his company Room Temperature Superconductors Inc was developing room-temperature superconductors; and that therefore Room Temperature Superconductors Inc would be a wonderful investment opportunity. He continues the pretense that the company developed something useful, even to this day.

    And then Goldes embarked on the pretense that his company Magnetic Power Inc was developing "NO FUEL ENGINES" based on "Virtual Photon Flux;" and then, on the pretense that MPI was developing horn-powered "NO FUEL ENGINES" based on the resonance of magnetized tuning-rods; and then, on the pretense that his company Chava LLC (aka "Chava Energy") was developing water-fueled engines based on "collapsing hydrogen orbits" (which are ruled out by quantum physics); and then, on the pretense that he was developing strictly-ambient-heat-powered "NO FUEL ENGINES" (which are ruled out by the Second Law of Thermodynamics).

    But of course, the laws of physics always make an exception for the make-believe pretenses of Mark Goldes.

    Goldes' forty-year career of "revolutionary breakthrough" pretense has nothing to do with science, but only with pseudoscience, pseudophysics, and relentless flimflam, in pursuit of loans and donations from gullible people who never mastered physics very well.

    Mark Goldes' "AESOP Institute" has engaged for many years in the very dishonest and unscrupulous practice of soliciting loans and donations under an endless series of false pretenses, that it is developing and even "prototyping" various "revolutionary breakthroughs," such as "NO FUEL ENGINES" that run on ambient heat alone - or run on "Virtual Photon Flux" - or on "Collapsing Hydrogen Orbits" - or even on the acoustic energy of sound from a horn.

    AESOP Institute's make-believe strictly ambient heat engine is ruled out by the Second Law of Thermodynamics. This has been understood by physicists for at least 180 years. There is no "new science" that has ever determined such an engine to be possible.

    AESOP Institute's make-believe "Virtual Photon Flux" engine is based on the idea that accessible electric power "is everywhere present in unlimited quantities" - which we know to be false.

    AESOP Institute's make-believe "Collapsing Hydrogen Orbits" engine is based on Randell Mills' theory of "hydrino" hydrogen, which every scientist knows to be false.

    AESOP Institute's make-believe horn-powered engine is based on the pretense that a magnetized tuning rod could somehow "multiply energy" - a ludicrous notion, which is obviously ruled out by the law of conservation of energy.

    AESOP Institute's very latest make-believe engine is a perpetual motion machine in the form of a self-powered air compressor, which proposes to use a turbine to compress air to spin the turbine to compress air to spin the turbine.

    AESOP Institute has never offered the slightest shadow of evidence that it is actually developing or "prototyping" any of these make-believe physics-defying "revolutionary breakthroughs." All it has ever offered are mere declarations that it is doing so - unsupported by any proof whatever, of any kind whatever.

    There are no "revolutionary breakthroughs" to be found on Goldes' fraudulent "Aesop Institute" website. There is only pseudoscience, relentless flimflam, and empty claims of engines that are ruled out by the laws of physics.
