I will look for the older references. Certainly Jed has most of them in the
lenr-canr.org database. Parkhomov's work stemmed from the Lugano report on
Rossi's hotCat - where Parkhomov, a retired Russian physicist, deduced the fuel
as primarily Ni + LAH, and tried it. He saw credible excess heat. You should
start by reading the Lugano report's analysis of the fuel and ash.The LENR
details of this system are unknown, but here is a guess in a nutshell. The
LiAlH4 breaks down to LiH and Al + nH2 as it is heated. At about 680C, both
the LiH and the Al are molten and they wet to the Ni, which is now reduced of
oxides by the H2. The liquid Al also partly acts as a getter for the the
oxygen in the system - taking it out of chemical play. LiH is an ionic
hydride, consisting of Li+ and H- in the molten metal. Wetted to the Ni, the
Li-H-Al supplies H- (anions) directly to the surface of the Ni, wherein a LENR
reaction of unknown detail happens. The reaction between Ni and H- could well
be as Piantelli describes in his patents. There are unsubstantiated shifts in
the 6Li/7Li isotopic ratio as well as unsubstantiated isotopic shifts in the Ni
and transmutation in the Ni.Excess heat seems to have an onset above 900C and
Parkhomov's latest experiments were run at 1200C. Experiments can exhibit
thermal runaway and burn out the apparatus.Chemical energy is typically
calculated as though the reactants were supplied with an unknown and unlimited
source of free O2 and burned. The primary energy is the burning of H2 with O2,
then the burning of the Li, and almost negligible is the chemical energy from
burning (oxidizing) the Ni. For the 2g of Ni and 0.2g of LAH, I have seen that
energy calculated in the range of 20kJ (but my memory could be off +100%/-50%).
Parkhomov measured about 100MJ output, about 5000x the chemical energy.On Fri,

Can someone post a link to something in the way of earlier work,
which might give an overview of this experiment and this approach?
I came in late to the show, and I'm confused as to what the reaction
is even believed to be here.
It's also apparent that some major chemical stuff was going on (from
the state of the reactors at the end of the experiment) but, while
LiAlH4 is presumably pretty seriously reactive, I wouldn't have
expected it to do much with nothing but Ni as a partner, since Li
and Al are surely much happier to donate electrons than Ni (didn't
check the half reaction potentials, tho, maybe nickel's more
reactive than I think).

Good morning Vorts,
Here is a link to my Google drive folder having the
English translation of A. Parkhomov's latest (6/23)
presentation. The link is to the folder containing
the translation, and if updates are needed, I will put
them in this same folder.
