    Some thoughts just for the purpose of thinking something...


    LiAlH4 decomposes at 400°C to LiAl and H2(gas) i.e. loads the cell with hydrogen
    LiAl is liquid above 900°C
    Al can getter clean NiO oxide layer from the heavily oxidised Ni grain surface by forming Al2O3
    Ni is not magnetic above 600°C So what is then special for Ni ?


    The third report is a step forward but there are still to many experimental question unanswered. Good thing is people can start to do different measurements and in 5-6 month positive or negative results will be here.


    then some metal hydride thoughts


    0.5g of H2 = 1 mole of H atoms gives 6E23 * 5MeV =3E30eV nuclear energy or 3E30 eV/6E18= 0.5E12J energy or 500.000MJ, so you need to burn 5mg of hydrogen to reach the 5000MJ that was produced in the 32days test. 5mg reflects in 50mg amount of of LiAlH4 complex hydride.


    Given 1cm3 volume of the cell containing Ni and LiAlH4 the H2 pressure in the cell at 1200 is
    P=NkT/V= 6E21*1.4E-23J/K*1.5E3K/1E-6m3 = 6*1.4/1.5*E(21-23-3+6) = 6E1N/m2 or 6Pascal or 0.06mbar not very high pressure


    (NiH needs at least 5000bar pressure at room temperature to be formed so NiH has never been part of LENR)
    Only possible loading is the dilute phase NiHx where x is rather low number but increases with temperature since Ni +H to NiHx is endothermic reaction but Ni + H to NiH (hydride) is slightly exothermic.


    Apparent loading of Ni to NIH seen by lot of people by a pressure drop is not due to NiH formation it is just due to pressure drop caused by Rydberg matter formation, the frozen plasma state of hydrogen is an entertaining comparison :)


    So look for answers in Leif Holmlid's numerous papers about Rydberg Matter and ultra dense hydrogen.

    Just some clarification


    1. Debye screening length is a term used in plasma physics (Widom's paper)
    2. Debye temperature is used in solid state physics for some obscure mathematical historical reason to describe the maximum frequency of vibration occurring in a crystal lattice. Diamond has the highest max vibration frequency (Debye temperature) of all materials since it has the strongest bond and the low mass of carbon and hence highest possible atomic vibration frequency 2pi*f=sqrt(mass/force constant).
