Titolo: PERLA DI MINARDI SULLA FUSIONE FREDDA

 non e' mai stato superato.
 
1) Ci spieghi perche' secondo te "studi teorici e fisici" non avrebbero valore?
 
2) Il lavoro a cui mi riferivo non e' teorico, ma sperimentale e pubblicato su di una rivista peer-review. Si vede che sei meno informato di un sasso!

EXPERIMENTAL
In the work reported here D+ was compressed galvanostatically into sheet, rod and cube samples of Pd from 0.1
M LiOD in 99.5% D2O + 0.5% H2O solutions. Electrode potentials were measured with respect to a Pd-D reference
electrodechargedtotheα-β-phase equilibrium. We report here experiments of several kinds:
(1) Calorimetric measurements of heat balances at low current densities (= 1.6 mA cm-2
) were made using a 2 mm
× 8 cm × 8 cm Pd sheet cathode surrounded by a large Pt sheet counter electrode. Measurements were carried out in
Dewar cells maintained in a large constant temperature water bath (300 K), the temperature inside the cell and of the
water bath being monitored with Beckman thermometers. The Heavy Water Equivalent of the Dewar and contents,
andtherateofNewton’slawofcoolinglossesweredeterminedbyadditionofhotD2O and by following the cooling
curves.
(2) Calorimetric measurements at higher current densities were carried out using 1, 2 and 4 mm diameter × 10 cm
long Pd rods surrounded by a Pt wire anode wound on a cage of glass rods. The Dewars were fitted with resistance
heaters for the determination ofNewton’slawofcoolinglosses;temperaturesweremeasuredusingcalibrated
thermistors. Experiments with rods up to 2 cm in diameter will be reported elsewhere [5]. Stirring in these
experiments [and in those listed under (1)] was achieved, where necessary, by gas sparging using electrolytically
generated D2. Measurements at the highest current density reported here (512 mA cm2
) were carried out using rods
of 1.25 cm length; the results given in Table 1 have been rescaled to those for rods of 10 cm length.
(3) The spectrum of γ-raysemittedfromthewaterbathduetothe(n,γ)reaction
1H + n(2.45 MeV) =
2D+γ(2.5MeV) (vii)
was determined using a sodium iodide crystal scintillation detector and a Nuclear Data ND-6 High Energy Spectrum
Analyzer. The spectrum was taken above the water immediately surrounding an 0.8 cm × 10 cm Pd-rod cathode
charged to equilibrium; it was corrected for background by subtracting the spectrum over a sink (containing
identical shielding materials) 10 m from the water bath.
The neutron flux from a cell containing a 0.4 × 10 cm Pd-rod electrode was measured using a Harwell Neutron
Dose Equivalent Rate Monitor, Type 95/0949-5. The counting efficiency of this Bonner-sphere type instrument for
2.5 MeV neutrons was estimated to be ≈2.4x10-4
and was further reduced by a factor ≈100duetotheunfavorable
configuration (the rod opposite the BF3-filled detector). The background count was determined by making
measurements 50 m from the laboratory containing the experiments; both locations were in the basement of a new
building which is overlain by 5 floors of concrete. In view of the low counting efficiency, counting was carried out
for 50 h. Measurements on a 0.4 cm × 10 cm rod electrode run at 64 mA cm
-2
gave a neutron count 3 times above
that of the cosmic ray background.
(4) The rate of generation/accumulation of tritium was measured using similar cells (test tubes sealed with
Parafilm) containing 1 mm diameter × 10 cm Pd-rod electrodes. Measurements on the D/T separation factor alone
were made using an identical cell containing a 1 mm diameter × 10 cm Pt electrode (this measurement served as a
blank as the H/D separation factors on Pd and Pt are known to be closely similar). 1 ml samples of the electrolyte
were withdrawn at 2 day intervals, neutralised with potassium hydrogen phthalate and the T-content was determined
usingReadyGelliquidscintillation“cocktail”andaBeckmanLS5000TDcountingsystem.Thecounting
efficiency was determined to be about 45% using standard samples of T-containingsolutions.Theβ-decay
scintillation spectrum was determined using the counting system.
In these experiments, standard additions of 1 ml of the electrolyte were made following sampling. Losses of D2O
due to electrolysis in these and all the other experiments recorded here were made up by using D2O alone. A record
of the volume of D2O additions was made for all the experiments.
In all of the experiments reported here all connections were fitted into Kel-F caps and the caps were sealed to the
glass cells using Parafilm.
Results for the mass spectroscopy of the evolved gases and full experimental details for all the measurements will
be given elsewhere [5].

 1) Ci spieghi
 
Direi che ci siam gia' passati da qua no? Mi spiace, ma non ci tengo a 
parlare con gente che apre thread ad personam in un ng di politica.
 
C'e' un thread aperto, la discussione va avanti la', i thread ad 
personam sono una cosa talmente patetica che non riesco proprio a seguirli.

C'e' gente che ha una vita fuori del ng, ma non preoccuparti, tieni pure 
qualche riga di carita', vorrei mai averti sulla coscienza.
