JR: 405 deg C is a huge difference.
Yes, but it is proof of nothing other than an inverted temperature profile.
* Assuming the temperature difference is real, and not an instrument
artifact, it is proof that a great deal of heat originated from inside the
reactor,
OK. But is it chemical heat? Jiang used 20 times more active fuel (!!!),
compared to Parkhomov or Rossi. And the active run was not long enough β only a
few hours. He has arguably not eliminated a chemical contribution with this
short run, since the LAH has significant chemical energy (in addition to
whatever LENR takes place).
Jiang says βthe amount of powder fuels (Ni + 10% (in weight) LiAlH4) is 20 g --
filled in a nickel cell.β If you count the nickel cell itself as also being
active, then this is more than a factor of 20 greater than Rossi. It should be
noted that tanked hydrogen is available in addition, which should be
unnecessary so disconnect it.
The chemical energy of LAH phase-change and of hot hydrogen escaping from LAH
can appear as excess heat in the core, at least to the extent it is retarded
from transfer to the surface. The core fuel was held in a vacuum, so chemical
heat is retarded.
Due to the 2nd law of thermodynamics, a passive system cannot move heat from a
cold source to a hot destination, but the law permits extreme minimization of
thermal flux so the temperature gradient becomes amplified in a vacuum. Bottom
line - If additional chemical heat, fueled by LAH in the core is retarded by
the vacuum conditions, it appears to have a much larger signature than the
un-retarded joule equivalent.
The solution, and the proper technique, is not a mystery β
1) provide a much longer run time. (factor of 10x)
2) use adequate thermocouples (at least for the core)
3) show a similarly long calibration run
4) use 2 grams of LAH without nickel, and without the nickel tube, in the
calibration run (to provide the identical chemical energy). A good substitute
for the nickel would be 18 grams of aluminum or magnesium powder.
