Izgleda da ovi u NASA-i ne čitaju vikipediju :D

"Cold fusion is a hypothesized type of nuclear reaction that would occur at, or near, room temperature. This is compared with the "hot" fusion which takes place naturally within stars, under immense pressure and at temperatures of millions of degrees, and distinguished from muon-catalyzed fusion. There is currently no accepted theoretical model that would allow cold fusion to occur."
https://en.wikipedia.org/wiki/Cold_fusion

"LENR is a type of nuclear energy based on the weak force. It has similar characteristics to fission and fusion, except there is no harmful radiation or hazardous waste. As an energy source, LENR works by generating heat in a catalyst process. The fuels or materials that are usually used in the LENR process are nickel metal (Ni) with hydrogen gas (H) or palladium (Pd) with deuterium (D). The initial testing and theory show that radiation and radioisotopes are extremely short lived and can be easily shielded.
LENR would be an ideal energetics solution. It could meet the world’s energy requirements while being cleaner and safer than current methods. NASA’s interest in LENR increased after the Widom-Larsen Theory was published. NASA began conducting experiments to determine how the LENR surface reactions occur and their characteristics. One appealing application for LENR previously identified by NASA is single-stage-to-orbit vehicles. LENR’s high energy density would be a huge advantage for these types of vehicles. NASA conducted a study in 2009 to design a LENR powered launch vehicle. LENR enabled very high performance engines that could revolutionize access to space."

Enivej, termin "hladna fuzija" je prilično nesretno odabran (nisam siguran, ali čini mi se da ga je štampa sama odabrala nakon objave F-P eksperimenta), izgleda da je detektiran treći tip nuklearnih reakcija, koji bi potencijalno mogao biti novi izvor energije, barem 4 000 puta veće gustoće od najboljih kemijskih izvora koje imamo, i što je najljepše, u samom procesu bez nezgodnih nusprodukata kao opasna zračenja ili kemijska zagađenja.

Bit će zanimljivo vidjeti kako će se stvari dalje razvijati ako američko Ministarstvo obrane krene s projektima istraživanja na tom polju. Očito je da civilni energetski sektor, tj. onaj dio koji je u rukama fosilnih lobista, nema baš žarke želje za promjenama.

Hmmm... izgleda da je onaj CF riport pred američkim kongresom, koji sam spomenuo par postova prije, odgođen, a kako će sad republikanski fosili pored većine u oba doma imati još i antiznanstveno nastrojenog precednika-fosila, jedina nada da bi se istraživanje nastavilo je da vladini vojni savjetnici za strateška pitanja dignu paniku zbog gubljenja tehnološke prednosti i ugrožavanja domovinske sigurnosti.

Kad smo kod US Army i CF/LENR, završni izvještaj Mosier-Boss tima sa SPAWAR-a i suradnika iz JWK International i sa New Mexico univerziteta:

INVESTIGATION OF NANO-NUCLEAR REACTIONS IN CONDENSED MATTER
...
5.0 CONCLUSIONS (pg 83.)
...
Taken all together, this is probably the largest, most comprehensive body of work in the
LENR field. The work has received international attention.
...
On November 2011, the LENR research at SSC-Pacific was terminated. The official reason
given by SSC-Pacific’s PAO, Jim Fallin, to Steve Krivit of New Energy Times for the
termination the LENR work at SSC-Pacific is:
“In response to your recent query,” Fallin wrote, “while I won’t discuss details of
our internal decision-making processes, I will confirm SPAWAR plans no further
low-energy nuclear reaction (LENR) research. There are other organizations
within the federal government that are better aligned to continue research
regarding nuclear power. We have taken initial steps to determine how a
transition of low-energy nuclear reaction (LENR) research might occur.”
The implications of this statement are that both SPAWAR HQ and SSC-Pacific say that the phenomenon is real and that it is nuclear in nature.

Istraživanja tima sa SPAWAR-a (koji je do tada u peer-reviewed žurnalima objavio nekoliko desetaka radova na tu temu) naglo su prekinuta kada je na dužnost došao novi zapovjednik vice-admiral Patrick Brady i 9. 11. 2011. izdao naredbu da se sve obustavi, a neutrošena sredstva dana timu na raspolaganje povrate, uz obrazloženje kako razvoj novih izvora energije nije u nadležnosti institucije koju on vodi (premda se tamo bave i razvojem brodskih i podmorničkih propulzija).

Još jedna zanimljivost: izvještaj američke obavještajne agencije Defense Intelligence Agency (DIA) (koja je u rangu NSA i CIA-e), od 13. 11. 2009., u kojem su pobrojani svi nacionalni i internacionalni laboratoriji, timovi, i institucije koji su objavili pozitivne pomake u istraživanjima hladne fuzije / niskoenergetskih nuklearnih reakcija.

Još dva odlična nova članka koja govore da je vrlo izgledno kako je počinjeno otkriće nove nuklearne reakcije, i da je moguće za komercijalnu eksploataciju.
http://phys.org/news/2016-11-cold-fusio ... ealed.html
http://cen.acs.org/articles/94/i44/Cold ... years.html

... i jedan iz 2010., ali također daje odličnu sliku o tome koliko je sve ozbiljno:
http://phys.org/news/2010-03-cold-fusio ... tream.html

I zato bi vrijedilo sve staviti pod jedan međunarodni objedinjeni projekt kao što je ITER (koji za sada samo guta novce bez značajnijih rezultata, slično kao i svi ostali eksperimentalni reaktori sa vrućom fuzijom, već zadnjih 60 godina).

Možda su fizičari konačno našli dokaze za petu elementarnu silu (pored gravitacije, elektomagnetske, jake i slabe nuklearne).

https://en.wikipedia.org/wiki/Fifth_force
https://cosmosmagazine.com/physics/have ... -of-nature
https://news.uci.edu/research/uci-physi ... of-nature/
https://journals.aps.org/prl/abstract/1 ... 117.071803

To bi bilo otkriće u rangu otkrića i objašnjenja nuklearnih reakcija.
Zašto ovo nije tako sigurno?
The discovery of a fifth force of nature is an extraordinary claim, requiring extraordinary evidence. Right now, the evidence is ordinary at best.

Naravno, predaleko je još od toga da bi ugrozilo etablirane komercijalne interese, pa nije dočekano na nož kao otkriće CF/LENR. :kava:
