attached: CV, List and the 373K article. We have shown last year that the 373K superconductors are real. For colleagues, who are aware that any material with a resistance visibly less then Cu is superconductor-on the right side we show the the 373 K tape in series with an identical copper tape being blown by 137 A current and the superconductor tape is intact.
THE FIRST EVER PURE MEISSNER EFFECT VIDEO IS POSTED HERE. ALL OBSERVATIONS OF LEVITATION ARE NOT STRICTLY A MEISSNER EFFECT(eg.see floating frogs). IN THE DEMONSTRATIONS WITH Y1Ba2Cu3O7-c THERE ARE FORCES DUE TO THE CURRENTS OF THE ABRIKOSOV FLUX LINES LATTICE. THE LOW FIRST CRITICAL MAGNETIC FIELD IS RESPONSIBLE FOR DISKS ORIENTED PERPENDICULAR TO THE MAGNETIC FIELD AND NOT PARALLEL.
Our products include Room Temperature high current carrying tapes, Josephson Junctions and High Power THz sources transported along the cable as shown here. Welcome!

-There is some misunderstanding of the MeissnerEffect (see HyperPhysics - a wrong one) . In pure form it occurs below the critical field Hc1 =110Gs for YBCO with Tc=93K. Shown here on the left is a 373K sample stabilized by the attraction with its image (approximately-exact only for a semi-infinite 1.4 T magnet). Evidently it has a first critical magnetic field Hc1 larger then 1.4 T. On the right top photograph small magnets stay similarly in vertical position and orient N-S. If the pellet below the small magnet is slowly turned in a circle the magnets stay along the same direction and do not turn with the pellet. Usually the YBaCuO samples levitation is shown with strong magnets way above the rather small Hc1 =110Gs. The levitation demos for YBaCuO (Tc =93 K) include the effect of the forces arizing from a complicated system of currents created by the Abricosov flux lines lattice. The top right photo has small magnets on top of 373K superconductors and one 373K superglass without a magnet with different color. The bottom right photo show 3 superconductors and one superglass pellet demonstrating their reflectivity difference at room temperature ( about 300 K).

The video 1-below is a THz waves generation via a cable in front of a police detector-3-loud and long signals repeated near the end after the noise. The second video - 2 is a copper tape in series with a superconductor tape of the same size. The copper tape is blown up by a 137 Amperes current, when a tape 373 K type superconductor in series remains intact.
