One of the leading experts on HTSC is the controversial hands-on theorist Joe Eck. In his latest installment, Eck adds to his emerging theory called the Periodic Compression Theory
http://www.superconductors.org/AEOHTSC.htm Ecks theory asserts that metals of disparate weights but identical oxidation states will produce superconductivity when positioned on opposite sides of an oxygen atom. Periodic compression from lattice vibrations causes the balance of valence to shift, creating a HOLE at the oxygen site. The positively-charged ion then facilitates the pairing of electrons in the hole, producing superconductivity via the Cooper pair. END Comment: Ironically, it can be observed that heat causes the vibration which causes the hole which causes the electron pairing so heat actually causes the superconductivity, in a way. The implication is that temperature control will always be needed in HTSC. Hopefully it can be as simple as fans. PRIOR post on HTSC: It may be worth noting that hole superconductivity may end up being broader than Hirschs theory. For instance, Hirsch mentions ring current several times in his many papers, which is somewhat of a middle ground between electron and hole superconductivity. In fact, he tries to explain everything under one banner, but I have yet to find a coherently worded explanation which placates all the possibilities. [Ecks theory could do that] These views on room temperature superconductivity come together in LENR, at least at the low end of the temperature scale and when aromatic catalysts are involved. They are probably not relevant to Parkhomov or high temperatures. This is particularly interesting to me since phenanthrene has been mentioned by Hirsch and others in the context of both ring current and hole superconductivity. However, I agree with Mark that Bremsstrahlung is unlikely from either type and would be self-quenching. Nevertheless, moderately fast electrons are possible so long as high temperature is avoided. Moreover, the advent and maintenance of RTSC (localized as ring current) would serve to explain why some types of LENR are difficult to pull off at the low end of the temperature scale (such as in Cravens NI-Week demo). The experiment must find the narrow region of temperature where a localized Meissner effect can coexist with optimized proton exchange and H3+ formation. This range probably peaks about 100° but finding it could be more meaningful than the high temperatures of the Parkhomov experiment, since self-sustaining heat is possible. From: Mark Jurich The radiation extends above 0.511 MeV in Trace #7 and this doesn't seem to fit with Hirsch's Theory (i.e., Hole Superconductivity as described in DOI: 10.1088/0953-8984/19/12/125217 ). Perhaps if the electrons were heavy (dressed) it could be valid. I would need to take a closer look. Also, I don't see Hirsch justifying Brems during creation of HSC, but a peak @ 0.511 MeV. ... I'm just glancing over things right now, so I may chime back. - Mark Jurich ------ Original Message ------ From: "Axil Axil" The x-radiation seen in the MFMP experiment called the "seventh segment signal" may have been caused by the initiation of "hole superconductivity" when the meissner effect expels electrons from the center of the superconducting material thereby producing x-rays through Bremsstrahlung. Also when the Hole superconductor is quenched, the same process produces electron collapse into the center of the dying superconductor also producing Bremsstrahlung.
