[Servizio speciale a cura di Davide Suraci] – Brian Ahern, esperto di scienza dei materiali presso il MIT di Boston e “Senior” da 17 anni presso i laboratori USAF di Hanscom – Air Force Base, ha replicato – in modo del tutto indipendente – una reazione nucleare a bassa energia e in nanoscala ottenendo 8 Watts.
Brian Ahern ha riprodotto il lavoro del fisico giapponese Y. Arata in un ordine di grandezza più manipolabile e quindi gestibile. Per la precisione, il processo รจ stato attivato utilizzando 10 grammi di nano-polveri dei seguenti elementi e nei rapporti: Zr (Zirconio) 66%; Nikel 21%; Cu (Rame) 13%, ha prodotto 8 Watts di potenza per quattro giorni ininterrottamente e senza radiazioni rilevabili oltre quella già presente nel fondo naturale. Lo Zirconio si trasforma in diossido di zirconio dopo la cottura.
Secondo le ultime indiscrezioni, Brian Ahern sta tentando anche di replicare il funzionamento dell'Energy Catalyzer di Rossi e Focardi migliorandolo ulteriormente per ottenere un aumento dell'efficienza del processo.
La comunità di studiosi delle LENR (Reazioni Nucleari a Bassa Energia) sembra sempre di più orientata (come, del resto hanno dimostrato Rossi e Focardi) a lavorare su livelli di nanoscala.
La descrizione delle fasi del processo LENR che hanno generato 5 Watts in due giorni. (Comunicazione originale di Brian Ahern al CMNS)
Riportiamo, a beneficio degli interessati (testo originale in inglese), la sequenza di un analogo esperimento di Brian Ahern in cui sono stati ottenuti 5 Watts in un paio di giorni.
The description of steps taken to get 5 watts for a few days (Message of Brian Ahern to CMNS).
Ames National Laboratory processed metal alloy foils via arc melting
followed by melt spinning. This is the Yamaura process employed by Arata
and others. The foils were baked in ordinary air at 445C for 28 hours.
The brittle, oxidized foils were placed in a tumble mill for 24 hours.
This resulted in 30 grams of black powder with a median grain size of about
40 microns.Presumably, each grain has about one million nanoscale islands of
NiCu inside.
The 30 grams occupies about 7 ml inside the 50 ml dewar. The system was
vacuum baked at 220C for 24 hours and cooled to room temperature.
H2 gas was added at 200psi. The pressure dropped only to about 185 psi over
twenty minutes. In these replication experiments the exothermic reactions
have had peak temperatures above 220C with substantial loading above 3.0 H/M
ratios. This time the temperature only rose by 2 degrees C.
The system was heated with a band heater to high temperature. There was no
controller. A rheostat was set at an arbitrary position and the system comes
to a an arbitrary temperature.The average power input was 90 watts.
After several hours the hydrated system was evacuated overnight at a
constant high temperature at 530C. The next day H2 gas was again added at
100psi and the temperature rose by 40C to 570C and came back down to 530C
after two hours. At the end of the day the dewar was again evacuated while
still at 530C overnight.
The third day repeated the same procedure. H2 gas was added at 100psi and
the temperature rose by 44C to 574C. However, this time it did not come back
to the initial temperature. It remained at the elevated temperature
overnight.
On the fourth day H2 gas was again added at 100psi and the system rose by
50C to 580C and again stayed at the elevated temperature indefinitely.
A rough calibration suggests that the 30 grams of hydrated nanopowder is
putting out 5 watts of excess power.
Yesterday Peter Gluck suggested that the relationship between loading and
excess power may be a myth. This seemed to be true for electrolysis with Pd
and heavy water where loading levels exceeding 0.9 D/M were a prerequisite
for observing excess power.
My loading level with this nanopowder sample as less than 0.1 H/M.
This 5 watt excess is very much less than Rossi, but it is a real and
repeatable experiment There was no radiation above the background level.
