Meni već pedeset godina jata vrabaca na grani cvrkuću da je vruća fuzija na ovom tehnološkom nivou prilično neizvediva.

"Race for cold fusion: Nasa, MIT, Darpa and Cern peer through the keyhole"

"In the 1980s, two scientists named Stanley Pons and Martin Fleischmann announced that they had developed a "cold fusion" process that could create fusion through chemical means, without the high temperature or pressure of stars and bombs. There was no theory to explain how that could be possible, and other scientists were unable to reliably reproduce the experiments, so cold fusion lacked credibility for most physicists. Some scientists have continued working on this idea though, and they sometimes call it "LENR." But this process is not what Dr. Zawodny is exploring.
"There are a lot of people who are trying to just build something without understanding anything," Zawodny said. "It worked for Edison and the light bulb, but it took him a long time and that was a simple system. This is very complex. And if they make something that just barely works, and accidentally one in a thousand works really, really well, it's going to take down a house with their trial-and-error method."
“Several labs have blown up studying LENR and windows have melted,” according to Dennis Bushnell, Langley’s chief scientist, in an article he wrote for NASA’s Future Innovation website. This, he wrote, indicates that “when the conditions are ‘right’ prodigious amounts of energy can be produced and released.” But it’s also an argument for the approach that the Langley researchers favor: master the theory first."

kako ide onaj zakon termodinamike? ..nema dzabe, tako nekako? :D
E pa u tome je stvar. Ta jedna kuglica kad upadne u vulkan i dobije energiju raspodijeli tu energiju ostalima da i one mogu upast. Lančana reakcija. Ovde je stvar kako to kontrolirano napravit. Nekontrolirano se napravilo odavno. Guglaj Car bombu. :zubo:
osim toga, kad vec pricas o silama, danas se barata s nekim novim silama. ok, elektromagnetna je nesto kao bila poznata prije da postoji, gravitacija.. gravitacija, jel to jos uopce sila? i kad? i gdje?
pa onda te jake, te slabe sile, te superjake, te nejake te nikakve te svakakve, zavisno kako kad i donekle i odnekle.. jos malo pa cemo imat demokraciju sila, postojat ce nebrojeno sila, svak ce svoje sile imat, ono, kako mu cefne. mislim, ako je sve relativno, pa sta ce onda sile bit apsolutne? ma nemoj? :D
Nema nikakvih novih sila. Četiri su bile prije bile su i sad. Jaka nuklearna, slaba nuklearna, elektromagnetska i gravitacija. Jedino šta se radi je da se na visokim energijama te sile pokušavaju opisat na isti način kad je jako vruće. Tako kad je svemir vručji o 1 000 000 000 000 000 Kelvina, onda se te dvi sile ne mogu razlikovat. Ali to je jedno te isto. Nema ništa novo.
to sta se tu hladi i kako i zasto i sta se tugrije i kako i zasto, nekako imam nekog pojma, malo mi je sve to plazmovito, ali ajd, neki ideju imam u glavi,
ustvari, sve je to u nekom principu jednostavno, analogno, a sad, to sto je tehnologija slozena i zahtjevna, to je eto, celofan.
mislim, sve je to nekako isto, slicno..nekad si mlin pokretao na kolo koje se vrtilo u rijeci, danas se plazma vrti na magnete, eto..
ali opet, ti noviji principi, ti neki nuklearni, pa to je staro vec vise od sto godina, tj vec vise od sto godina se postavljaju ista pitanja, jedino je eto, problem te tehnologije sto se mora cekat na nju, ali to.. fisija, fuzija, nekako sam ocekivao.. ili ocekujem neku novu revoluciju, pristup, pa nije valjda da cemo sve svodit na tu fisiju, fuziju, mlinska ta kola?
eto, jel imamo vec tih sila cudo jedno, struna, cega li vec, pa ajde, daj nesto iz toga novo, nesto da fercera zaozbiljno, daj taj skok neki tehnoloski vise, dosadila su vise mlinska kola, nafte, fizije, fusije, fuksije..sva se to samim sobom bavi.
evo, pusti kvanti, ovo ono i..? kakva korist? neko ce rec, a gle, pa na cemu sad ovo pises, jel na kompu?
mislim, jel to znaci da citava npr kvantna teorija sluzi nekako da se po njoj naprave kompovi koji bi jednog dana mogli bit toliko brzi da rjese probleme kvantne teorije?
ono, nes ti koristi puste od sve te nauke u vidu mobitela i kompjutera. ko ih jebe, nes ti koristi velike. samo stete ima. uglavnom. koristi imaju samo oni koji su u tome da bi od toga imali koristi od onih koji od toga nemaju koristi. tj, necija steta, tudja korist. vavik tako bilo. eto velike znanosti. :zubo:
Pa sve gori šta si nabrojija se računa koristeći kvantnu mehaniku. I fisije i fusije i sv ostala čudesa. Velik dio svjetske ekonomije se temelji na kvantnoj mehanici upravo zbog tih razloga. Jedna od najpreciznijih teorija koje imamo je kvantna elektrodinamika. Današnji fizičari se bave isključivo fizikon koja se opisuje kvantnomehanički. Ili se bave gravitacijon. :D
To šta ne fecera u smislu da moš napravit malu kutijicu i u nju uštekat kabel i da to daje struje, jebiga. :D

Kvantni kompjuteri ne rade tako ka šta misliš, nego imaju ograničeni skup stvari koje mogu radit jako brzo, dok ostale stvari ne mogu uopće. Laprdat po internetu na kvantnin kompjuterima vjerojatno nećemo nikad jer jednostavno to nije ista vrsta kompjutera.

..i, jedan detalj. ti magneti, kazes..kazu.. rade na 4k. sta uopce radi na 4 kelvina? ocito radi nesto. magneti rade. tj, kako to da se ta struja, ti elektroni, magnetoni sta li su, kako se to uopce krece na toj temperaturi, tj hladetini?
nesto se kao krece, tako ispada, ali meni ispada da se to ludilo krece sto je temperatura niza. ono, sto hladnije, to magneticnije. kako to?
Pa stvar je baš u tome. Kad oladiš materijal na tako nisku temperaturu, stvar postane sve uređenija i dobiješ makroskopsko kvantno stanje. Kvantna stanja su inače na mikroskopskoj skali, i jasno, ne vide se u svakodnevnom životu. Međutim, u takvim ekstremnim uvjetima kvantno stanje postane makroskopsko šta znači da se na makroskopski objekt počnu primjenjivat kvantne zakonitosti šta ima za poslijedicu nekakva čudna svojstva. A jedno od takvih svojstava je i supravodljivost.

Šta se tiče kretanja elektrona, u metalu na apsolutnoj nuli T=0, oni idu ko blesavi. To je poslijedica Paulijevog principa isključenja. Al priča o tome je za malo napredniji kurs. :zubo:

Nije šta ladnije, nego postoji oštra granica koja se zove kritična temperatura. I ispod te temeperature je otpor 0, bia pola stupnja ispod ili 10. I nije sve više magetičnije nego mi to radimo magnetičnije jer iskorištavamo da je otpor 0 pa puštamo blesavo jaku struju kroz to da stvorimo blesavoj jako polje.

a s druge strane, imamo tu plazmu koju je neko zagrijao na temperaturu visu od sunceve jezgre, ako se ne varam, a i ako se varam, sto se mene tice, to je tu negdje, dvajst, pedeset miljona kelvina gore dole, meni je to isto.
dakle, ti tokamaki i ekipa, te fuzije, to ustvari radi na popizdjenje. ono, ugriju atome, i onda oni popizde za popizdit, mogu di oce i sta oce, a to je ono sto se od njih i oce.
i kako sad to, ovo grijes da popizdi.. tj za popizdit ugrijes da bi to nesto radilo, aove magnete hladis i tek onda oni popizde, imas elektromagnetsko polje za popizdit. jel to znaci, sto hladnije, to elektromagnetskije?
Unda, izmišljaš pridjeve koje ne znan šta znače. :zubo:
Dobro si skužija prvi dio. Ugriješ sve da popizdi, da atomi izgube elektrone, da sve to ide ko blesavo.
Međutim, ovo s magnetima je drugačije. To s magnetima je ka u splitu u srid lita u tri manje kvarat kad je još vruće za popizdit i taman si ruča i ne da ti se maknit pa pustiš sve u kurac i ne daješ kontru ničemu jer ti se ne da. :D
mislim, ono, ima logike. u svim zvijezdama se odvijaju fuzije..barem dok su zvijezde..nekad se to zvalo..do kojeg ono bljeska..zeljeznog? nekog prije? silicijskog? ..ok, ako su male da ne zavrnu u supernovu ili crne rupe. ne znam danas jel se tu sta teorija promijenila, i tu, te fuzije i temperature se odvijaju.. gdje? sto je oko njih? pa oko njih je hladetina svemira, neki mali kelvinici, ako ih uopce ima.
a nesto ih mora bit, jer da ih nema, sve bi stalo, jelda? moralo bi stat? ili ne bi? ili cwemo sad o kvantumima opet, pa cemo o tome da mozda jest, a mozda i nije, tj nije, ali cim smo ga spomenuli, jest, a vjerojatnost da cemo ga spomenut je velika, ali ne znamo gdje cemo ga spomenut. ili znamo gdje cemo ga spomenut, ali ne i kad?
mislim, meni je sve to trla brla. ko kviz neki. puno informacija bez koristi. narocito kad ne pobijedis na kvizu. :zubo:


ok, pa nek rade kao i do sad, nek sve sklope i nek radi i nek nemaju pojma zasto to radi i kako. :D

dobro si rekao prije.. igraju se deca. zabavljaju. nesto treba radit, bilo sto. ili, kako bi fizicari rekli.. treba nekako utuc vrijeme. :D
Da, do željeza. Sve iza željeza je stvoreno u supernovama.

Fuzija se odvija u središitima zvjezda di se ipak stvari stignu malo ugrijat. I to zbog gravitacije koja sažme stvari i time uzrokuje da mali vodikovi atomčići popizde.U hladetini svemira ima temperature, i to 2.72 Kelvina, ako te baš zanima. :zubo:
Sad me pitaj kako se to zna? :D
I nije skroz bez koristi, tu i tamo se nešto sazna, pa se možemo kurčit time. :zubo:

- Conventional Understanding of the Coulomb Barrier:

o Fusion energy occurs when a proton penetrates into another atom’s nucleus, allowing it to fuse or transmute that atom into another element, releasing significant excess energy. The coulomb barrier is what prevents this from happening at normal pressures and temps.

o It normally takes a huge amount (~4 MeV) of energy for a proton to overcome the Coulomb barrier and penetrate into the atom. It is known that this can be reduced a bit with quantum tunneling effects.

o Even with tunneling, the level of energy required only exists today in stars. There are attempts underway to reach these levels using giant lasers such as ITER for ‘Hot Fusion’. LINK


- A Possible New Understanding of the Coulomb Barrier (BECNF Theory)

o Led by research from Dr. Yeong E. Kim of Purdue University and built upon work by many including Einstein-Bose, the traditional description of the Coulomb barrier is believed to be just a special case that is true only when an atom is isolated in a vacuum.

o The coulomb barrier can actually be very different when an atom is not isolated. For atoms within a metal lattice (grid), the Coulomb barrier of each atom is suppressed by surrounding, highly symmetric atoms.

o Within tiny cracks in the metal lattice (the NAE) and under very specific conditions (e.g. heat, pressure, EM pulsing, pre-loading, quantum tunneling) the Coulomb barrier remains suppressed allowing the H proton to fuse into the metal atom’s nucleus in a Bose-Einstein Condensate, creating a new element with one higher atomic number, releasing energy. This is achieved at low temps, instead of millions degrees for an isolated atom.

Nema tu ništa konkretno u tome što si pejstao.
I kako bi to točno radilo?
O kojem metalu je riječ i koliki bi bio Tc tom BECu?
Kako bi spriječio isparavanje BECa budući da fuzija proizvodi toplinu?
Pod pretpostavkom da to sve radi, kako bi napravio stroj koji bi iz toga vrtio generator budući da sumnjam da postoji BEC sa stvarnim materijalima kojem Tc ide preko 100 K? Mislim, moguće je da postoji, samo ja nisam čuo za takvu stvar.

"Abstract:
A method and apparatus for carrying out highly efficient exothermal reaction between nickel and hydrogen atoms in a tube, preferably, though not necessary, a metal tube filled by a nickel powder and heated to a high temperature, preferably, though not necessary, from 150 to 5000C are herein disclosed. In the inventive apparatus, hydrogen is injected into the metal tube containing a highly pressurized nickel powder having a pressure, preferably though not necessarily, from 2 to 20 bars."

"Hydrogen Nickel LENR (Low Energy Nuclear Reaction) Andrea Rossi Cold Fusion - The E-Cat Energy Revolution"
http://www.xvi-ncbc.com/news/hydrogen-n ... revolution

https://en.wikipedia.org/wiki/Energy_Catalyzer


Istraživački novinar i od strane IARPA-e priznati autoritet Steven Krivit (https://en.wikipedia.org/wiki/Intellige ... iarpa.gov/), koji je inače sam zagovaratelj i prezentator tzv. hladne fuzije, navodno je Rossija uhvatio u namještanju rezultata njegovog uređaja.

O Krivitu:
http://news.newenergytimes.net/about-new-energy-times/
a ima i on svoje kritičare:
http://www.e-catworld.com/2012/02/05/sw ... ld-fusion/

Ovdje su neki noviji članci o toj temi, koji pokazuju da su i Japanci i te kako angažirani na tom polju:
http://news.newenergytimes.net/


Zato bi čitavu tu zbrku moglo riješiti jedno pošteno, neprofitno, transparentno i obilato financirano istraživanje, umjesto što se time bave entuzijastični pojedinci i privatne kompanije. Ali to se ne događa jer je cijela ta priča oko hladne fuzije u startu stigmatizirana kao patološka znanost od strane jednog dijela fizičara za koje je sva fizika stala tamo negdje nakon detonacije hidrogenske bombe 1952.

"Mitchell Swartz of Jet Energy again demonstrated and lectured about his NANOR and Phusor cold fusion devices at the Massachusetts Institute of Technology MIT on Jan. 27. The lecture was part of Peter Hagelstein’s well known Cold Fusion 101 short course which is held every year at the end of January. Videos of all the lectures and demonstrations have been posted at several websites.

Swartz has achieved some impressive results with his NANOR according to the lecture. His lecture indicates that the NANOR device is a serious rival to Andrea Rossi’s ecat and Brillouin’s hot tube. The E-Cat World blog listed some impressive accomplishments for NANOR and PHUSOR including:

• Swartz was able to use a Phusor to run a Stirling (hot air engine). The Phusor made heat which ran the engine.

• At least one NANOR operated for 12 months an entire year. Four of those months were in a public demonstration in Hagelstein’s lab at MIT.

• At least one NANOR was able to produce 80 times more energy than it consumed for a period of 30 minutes last year. To be a viable energy source a device must generate several times as much energy than it consumes.

• The NANOR that operated for 12 months produced 14 times as much energy as it consumed.

• Like the E-cat Nanors can be connected together to produce a larger power source.
...

There’s also bad news: Dr. Sven Kullander one of the Swedish scientists who had observed and tested Andre Rossi’s ecat has reportedly died in his homeland. Kullander, a retired professor of High Energy Physics at Uppsala University attracted controversy by endorsing a report on the ecat’s energy output and observing the device with his colleague Hanno Essen.

Like Giuseppe Levi and Francesso Celani, Kullander was one of a small number of European physicists who were more receptive to LENR than their American counterparts. His death is definitely a loss to LENR and energy research."

"This site features a library of papers on LENR, Low Energy Nuclear Reactions, also known as Cold Fusion. (CANR, Chemically Assisted Nuclear Reactions is another term for this phenomenon.) The library includes more than 1,000 original scientific papers reprinted with permission from the authors and publishers. The papers are linked to a bibliography of over 3,500 journal papers, news articles and books about LENR."

"Cold Fusion Being Studied at MIT
[The MIT course consisted of the demonstration and five days of presentations by Professor Hagelstein who explained his cold fusion theories. Hagelstein is a long time LENR proponent who is part of Cold Fusion Energy Inc, a consortium of scientists dedicated to commercializing cold fusion. It is not known whether there is a connection between that group and Jet Energy Inc. Halestein is a principal investigator at MIT’s Research Laboratory of Electronics."/i]
http://energycatalyzer3.com/news/cold-f ... ied-at-mit

*****

"The National Aeronautics and Space Administration or NASA has announced that it is working to develop a low energy nuclear reaction (LENR) or cold fusion power source. The agency has posted a video online that features a senior research scientist discussing LENR and explaining how it works.
The scientist is Dr. Joseph Zawodny a Senior Research Scientist at NASA’s Langley Research Center in Virginia near Washington DC.
...
Zawodny did not mention Rossi or e-cat but he described a home use of the process that sounds a lot like Rossi’s. He mentioned that it could be used for heating, cool, water heating and electricity production in the home.
...
Interestingly enough Dr. Dennis M. Bushnell another senior scientist at Langely who is also involved in LENR research is not mentioned or shown in the video.
Nor or are any high level NASA officials shown. Scientists are shown working at computers but no LENR devices are shown. Instead stock footage of planes, trains and trucks is shown and fossil fuels are mentioned.
This is a very interesting development especially when there is widespread public interest in LENR and public pressure to investigate it. Combined with reports that the US Department of Energy could be changing its mind on the topic this is really good news. LENR skeptics won’t be able to dismiss Zawodny as a “cold fusion crank.”

There are some interesting implications from this, NASA could be getting ready to ask Congress for funding for LENR research. Or the Agency could be getting ready to patent a process. If that happens it could affect both Andrea Rossi and the Greek company Defaklion that claim to have working LENR heating devices. Rossi is selling such a device right now. Both he and Defkalion are planning to bring out home heating units using LENR this year.

One interesting development could be that NASA is planning to commercialize LENR. That could lead to a legal battle with Rossi and the companies he has licensed. There have been some unconfirmed rumors that NASA has purchased one of Rossi’s e-cat cold fusion devices. Other rumors indicate that the Defense Advanced Research Projects Agency at the Pentagon or DARPA was the customer.

I also have to wonder if NASA has a working LENR device of some sort. If it does that could be a real game changer. We would also have to wonder why NASA hasn’t revealed the device to the public or the press. Perhaps they’re waiting for tests or a patent."

Sve ti već piše.
Nema tu ništa konkretno u tome što si pejstao.
Kako nema, ima puno toga.
I kako bi to točno radilo?
Jebote, ti sad očekuješ da tu neki forumaš u đepu ima točan nacrt uređaja koji može izazvati revoluciju u svjetskoj energetici, ekonomiji i geopolitici? Evo još jednom šta su malo veće face od mene napisale:
"Abstract:
A method and apparatus for carrying out highly efficient exothermal reaction between nickel and hydrogen atoms in a tube, preferably, though not necessary, a metal tube filled by a nickel powder and heated to a high temperature, preferably, though not necessary, from 150 to 5000C are herein disclosed. In the inventive apparatus, hydrogen is injected into the metal tube containing a highly pressurized nickel powder having a pressure, preferably though not necessarily, from 2 to 20 bars."

http://www.journal-of-nuclear-physics.com/?p=96&cpage=1

"Hydrogen Nickel LENR (Low Energy Nuclear Reaction) Andrea Rossi Cold Fusion - The E-Cat Energy Revolution"
http://www.xvi-ncbc.com/news/hydrogen-n ... revolution

https://en.wikipedia.org/wiki/Energy_Catalyzer
- to su opisi Rossijevog uređaja, za koji nije baš izgledno da je spreman za komercijalnu upotrebu

- dolje je opis uređaja na 32 stranice konkurentske kompanije koja je po nekim LENR/CF krugovima najdalje odmakla prema komercijalizaciji:
http://brillouinenergy.com/~brilloui/wp ... thesis.pdf
O kojem metalu je riječ...
U opisu Rossijevog E-Cat lijepo piše: nikl i vodik se fuzioniraju u bakar, paladij su koristili Fleishman i Pons, u Japanu, Kini, Indiji, Izraelu i drugdje su rađeni pokusi sa platinom, titanijem, supravodljivom keramikom, deuterij-paladij nanočestice se spominju u zadnjem videu koji naravno nisi pogledao... -zavisi o metodama kojih ima više kao što postoji i više metoda i različitih eksperimentalnih reaktora za postizanje vruće fuzije, i isto tako podijeljena su mišljenja koja od njih može biti komercijalno upotrebljiva.
... i koliki bi bio Tc tom BECu?
Kako bi spriječio isparavanje BECa budući da fuzija proizvodi toplinu?
Pod pretpostavkom da to sve radi, kako bi napravio stroj koji bi iz toga vrtio generator budući da sumnjam da postoji BEC sa stvarnim materijalima kojem Tc ide preko 100 K? Mislim, moguće je da postoji, samo ja nisam čuo za takvu stvar.
- možda i postoji:
http://www.superconductors.org/141C136C.htm

- možda rezultati eksperimenata od 1989. pa dalje govore da je Koulombova barijera samo specijalni slučaj i da treba naći generalnu teoriju koja će objasniti opažanja (hmm, specijalna, pa generalna teorija... zvuči poznato...)

- možda i ta generalna teorija već postoji, ili bar njeni dijelovi:
http://sjbyrnes.com/cf/
http://www.ans.org/pubs/journals/fst/a_47
http://journals.aps.org/prl/abstract/10 ... tt.76.3679
https://en.wikiversity.org/wiki/Cold_fusion/Theory

- možda sve piše tu negdje u ovom kratkom "A Student’s Guide to Cold Fusion" vodiču na 52 stranice koji je 2012. sastavio umirovljeni doktor nuklearne kemije iz Los Alamos Nacionalnog Laba Edmund Storms
http://lenr-canr.org/acrobat/StormsEastudentsg.pdf

- možda bi nam sve mogao objasniti i svojevremeni Oppenheimerov suradnik i sudobitnik Nobelove nagrade sa Feynmanom i Tomonagom 1965. godine, kvantni fizičar Julian Schwinger koji je napustio American Physical Society nakon što su mu odbili objaviti radove u vezi hladne fuzije
https://en.wikipedia.org/wiki/Julian_Schwinger
http://arxiv.org/ftp/physics/papers/0303/0303078.pdf
https://en.wikipedia.org/wiki/American_Physical_Society

- možda je već objasnio stalni suradnik MIT-a profesor Peter L. Hagelstein
https://en.wikipedia.org/wiki/Peter_L._Hagelstein

- možda su u pravu oni koji misle da tu nekog vraga ipak ima:

http://www.extremetech.com/extreme/1755 ... gy-markets
http://www.technewsworld.com/story/71916.html


Uglavnom, moje laičko mišljenje je da tu ipak ima dovoljno jakih "možda" da se potroši koja milijardica (kao što se troše za vruću fuziju), umjesto što se eksperimenti izvode ovako u podrumima sa sklepanom skalamerijom iz kućnih budžeta dok zagovornicima prijete stigme i lomače zbog hereze, i da okolo love u mutnom razne privatne kompanijice i pseudoznanstveni šarlatani, da bi se već jednom rasčistilo o čemu se zapravo radi. Jer jedan takav relativno jednostavan, dostupan, jeftin i moćan izvor energije koji djeluje predobro da bi bio istina, nije za bacit.

Gledaj, ja nemam ništa protiv hladne fuzije i bilo bi super da to radi i da bude čist izvor energije. Međutim, razgovarao sam s ljudima koji žive od nuklearne fizike koji kažu da je hladna fuzija sce dalje i dalje. Tvoje laičko mišljenje je takvo jer nemaš uvid u prave, ono što ja zovem konkretne, stvari u kojima ima malo više brojeva i stvarne fizike.

Onda ne znam šta si mislio, jer si napisao: "...BEC sa stvarnim materijalima kojem Tc ide preko 100 K?" jer meni BEC znači stanje materije pri niskim temperaturama, Tc kritičnu temeparaturu (ili kritičnu gustoću čestica), 100K je -173C°C, stvarni materijal je stvarni materijal i pitanje je u kontekstu kako konkretni generator radi, tojest jesu li potrebne ekstremno niske temperature a ne vidim za što drugo bi trebale u praksi biti potrebne nego za supravodljivost (iako nisam siguran koliko su pouzdani rezultati tog Joe Eckea).
Jer postojanje efekta hladne fuzije u laboratorijima je znanstveno verificirano

a to što tek treba pronaći zadovoljavajuće teorije je drugi par opanaka.

Ili možda ni sonoluminiscencija ne postoji jer nema validno teorijsko objašnjenje?

Ja sam ipak očekivao pokušaj nekakvog mentalnog angažmana na napisano u svrhu konstruktivne rasprave.
Mentalni angažman je ipak previše zbog idućeg tvog komentara:
Onda ne znam šta si mislio, jer si napisao: "...BEC sa stvarnim materijalima kojem Tc ide preko 100 K?" jer meni BEC znači stanje materije pri niskim temperaturama, Tc kritičnu temeparaturu (ili kritičnu gustoću čestica), 100K je -173C°C, stvarni materijal je stvarni materijal i pitanje je u kontekstu kako konkretni generator radi, tojest jesu li potrebne ekstremno niske temperature a ne vidim za što drugo bi trebale u praksi biti potrebne nego za supravodljivost (iako nisam siguran koliko su pouzdani rezultati tog Joe Eckea).
Odavde je očito da nemaš pojma o čemu tipkaš. BEC znači Bose - Einstein Condensate ili na hrvatski bozeajnštajnov kondenenzat. To je posebno stanje u kojem se mogu naći čestice. I ne bilo kakve čestice nego čestice cjelobrojnog spina koje zbog tog svojstva imaju simetričnu valnu funkciju na zamjenu čestica. Zbog toga se dvije čestice mogu naći u istom stanju tj. ne trebaju zadovoljavati paulijev princip isključenja. Bose - Einstenov kondenzat nije ništa drugo nego stanje kada se makroskopski broj čestica nađe u osnovnom stanju. Tada se kvantni efekti mogu vidjeti na makroskopskoj skali.
Supravodljivost je sličan efekt kada se također na niskim temperaturama formiraju Cooperovi parovi koji su zaslužni za efekte supravodljuvosti. Dakle, to nije skroz ista stvar, iako se mogu povlačiti nekakve paralele.
Tc je kritična temperatura. Budući da se radi o kvantnim efektima, prijelaz je jako oštar. U slučaju BECa tada počinje pojava kondenzata, a kod supravodiča tada se javljaju supravodički efekti.

Ova čitava besplatna lekcija iz statističke fizike ima svrhu da ti objasni moja prethodna pitanja. Ne znam jesi li primjetio, ali u linku koji si postao pojavljuje se nuklearna fuzija uz pomoć BECa. To mi je bilo interesantno jer su takvi kondenzati inače na jako niskim temperaturama. Pitao sam te nekoliko stvari, a ti si odgovorio sa skroz nečim trećim što nema veze s time.

Doviđenja i hvala na pažnji.
Ako te još nešto zanima slobodno pitaj.

Mda, priznajem; nikad prije čuo za BEC, sve postove mi nasumično tipka čopor majmuna, a pod: "jer meni BEC znači stanje materije pri niskim temperaturama" mislio sam zapravo na stanje krumpira u hladnoj pećnici, a ne stanje elementarnih čestica. :cerekava:
Enivej, drago mi je što si savladao aktualni nastavni program, ali zar stvarno misliš da je to zaključna riječ u modernoj fizici elementarnih čestica?
Jer recimo postoje stričeki koji su još davno prije završili isti nastavni program (od kojih neki su ga i sami svojim znanstvenim radovima inicirali) pa svejedno sa dobrim razlozima misle da je BEC samo dio te teorijske priče:
"... As I was searching a possible theoretical explanation for the claimed discovery, I realized that the conventional nuclear theory could not be applied to deuteron fusion in metal...
My third awakening and illumination happened when I and Zubarev developed a theory of Bose-Einstein condensation nuclear fusion (BECNF) for deuteron fusion in a metal. The results were published in 2000 [“Nuclear fusion for Bose nuclei confined in ion traps,” Fusion Technology 37, 151 (2000); “Ultra low-energy nuclear fusion of Bose nuclei in nano-scale ion traps,” Italian Physical Society Conference Proceedings 70, 375 (2000)].
http://www.physics.purdue.edu/people/fa ... ekim.shtml My third awakening came in 2000 with realization that the BECNF theory is capable of explaining the F- P effect and all of Huizenga’s three miracles."
http://egooutpeters.blogspot.ro/2013/06 ... voice.html
Onaj tko teoretski objasni pokuse koji potvrđuju hladnu fuziju dobit će Nobelovu nagradu, a ne indeks na faksu.

Doviđenja i hvala na pažnji.
Ako te još nešto zanima slobodno pitaj.
Hvala tebi al nisi se trebao toliko trudit, jer kad budem poželio da postanem konformistički fahidiot upist ću fakultet koji za to izdaje društveno prihvaćene certifikate a ne dopisnu školu. Za sve ostalo tu je internet.
Al ako goriš od želje za objašnjenjima, možeš nam tu objasnit sonoluminiscenciju, pa skoknut do Štokholma.

Uostalom krajnje je debilno prtljati po atomima dok istovremeno već postoji besplatni, kao energent savršeno čist, i praktično neiscrpan izvor energije na bazi fuzije koji za mnogo redova veličina nadmašuje trenutne civilizacijske potrebe, zvan Sunce, koji se može pohranjivati npr. u ovom obliku:
https://en.wikipedia.org/wiki/Ammonia#As_a_fuel

Al moramo svi mi pušit priču koju prodaju civilizacijski paraziti sa svojim fosilnim bajkama, jelda, jer nekima bacaju mrvice iz svoje kopanje?

https://www.youtube.com/watch?v=lQWIubQyaao
http://www.nrel.gov/hydrogen/proj_produ ... ivery.html

Now, 30 miles away at Valparaiso University, scientists have built a solar-powered, high-tech furnace to test technologies they hope one day will refine lightweight, low-carbon magnesium for automotive components as well as produce greenhouse gas-free hydrogen to power the vehicles.
“Our goal is to produce magnesium with 90 percent less fossil fuel energy and 93 percent less carbon emissions,” says Scott Duncan, a professor of mechanical engineering at Valparaiso. His team won a $2.3 million Department of Energy grant to develop the process. The National Science Foundation awarded Valparaiso $300,000 for the hydrogen project.

A i sa baterijama se napreduje.

Lithium-air batteries have the potential of 5–15 times the specific energy of current lithium-ion batteries.
https://en.wikipedia.org/wiki/Lithium%E ... ir_battery

Because they "breathe" oxygen from the air to power the chemical reactions that release electricity rather than storing an oxidizer internally like lithium-ion batteries do, lithium-air batteries boast an energy density comparable to gasoline. This would allow an electric car with a battery one-fifth the cost and weight of those presently on the market to drive 400 miles (650 km) on a single charge.

Their findings reveal a promising way forward for Li-air technology, at a time when many other research groups have given up. As more researchers return to the subject following this breakthrough, perhaps a commercial Li-air battery will finally become reality.

The new design discussed in the paper relies on lithium hydroxide, and is far more water-tolerant than previous designs. The team redesigned the battery electrode and shifted the makeup of the electrolyte, reducing the voltage gap between the charge and discharge states. Dendrite formations, however, remain a problem, and the demonstrator battery can only be cycled in pure oxygen. That’s a significant problem for any battery that’s intended to run in the atmosphere. These barriers are part of why the researchers are still cautioning that their cells remain a decade away from commercial use.

Could Al-air be the next big thing?
New battery technologies and announcements are a dime a dozen, but there’s reason to think that a workable Al-air technology could deploy within the next 2-5 years. Multiple manufacturers are working on commercializing designs (Alcoa partnered with Phinergy in 2013 with plans for a 2017 debut), and aluminum is abundant and relatively cheap. Al-air batteries have actually been used in specialized military applications for years, which is important — it means there’s some pre-existing expertise and known characteristics that can be leveraged to create additional capacity.

Inčresting:

Even by the most conservative assumptions as to the errors in the measurements, the result is still one order of magnitude greater than conventional energy sources.

Impact of Advanced Energy Technologies on Aircraft Design
The impact of low energy nuclear reaction (LENR) technology on the design of aircraft is examined. Energy conversion possibilities considered and a Brayton cycle engine with an LENR heat exchanger is selected. Potential aerospace applications of LENR devices are discussed and a high altitude long endurance (HALE) unmanned aerial vehicle with multi-year endurance is conceptualized with primary focus on energy management. © 2014, American Institute of Aeronautics and Astronautics Inc.

Još zanimljivije - službeni dokument zastupničkog doma SAD sa planom za fiskalnu 2017. za vojna pitanja:

NATIONAL DEFENSE AUTHORIZATION ACT FOR FISCAL YEAR 2017
R E P O R T OF THE COMMITTEE ON ARMED SERVICES
HOUSE OF REPRESENTATIVES
ON
H.R. 4909
together with
ADDITIONAL VIEWS
[Including cost estimate of the Congressional Budget Office]
MAY 4, 2016.—Committed to the Committee of the Whole House on the State of the Union and ordered to be printed

...
Low Energy Nuclear Reactions (LENR) Briefing
The committee is aware of recent positive developments in developing low-energy nuclear reactions (LENR), which produce ultraclean, low-cost renewable energy that have strong national security implications. For example, according to the Defense Intelligence Agency (DIA), if LENR works it will be a ‘‘disruptive technology that could revolutionize energy production and storage.’’ The committee is also aware of the Defense Advanced Research Project Agency’s (DARPA) findings that other countries including China and India are moving forward with LENR programs of their own and that Japan has actually created its own investment fund to promote such technology. DIA has also assessed that Japan and Italy are leaders in the field and that Russia, China, Israel, and India are now devoting significant resources to LENR development.
To better understand the national security implications of these developments, the committee directs the Secretary of Defense to provide a briefing on the military utility of recent U.S. industrial base LENR advancements to the House Committee on Armed Services by September 22, 2016. This briefing should examine the current state of research in the United States, how that compares to work being done internationally, and an assessment of the type of military applications where this technology could potentially be useful.

Saudi Arabia prepares to break oil-wealth dependency

In January, the Kingdom formally launched a new information, communication and technology fund worth $133 million in an attempt to pioneer new ventures. So given it is looking at new ideas, but has a long historical connection with energy it would be no surprise to see the Saudis looking for new energy industrial joint ventures.

A potential avenue that could be explored is that of Low Energy Nuclear Reactions or Lattice Enabled Nanoscale Reactions (LENR). This is a chemical/physical event where anomalous amounts of heat are generated when certain metals absorb hydrogen or deuterium and an external stimulus such as an electric current is directly applied.

A potential partner for KSA to partner with is Industrial Heat LLC that was incorporated in 2012 and is based in Raleigh, North Carolina. This firm has already been granted the license to sell and manufacture energy catalysers “E-Cats” in Saudi Arabia. Therefore, I do not think it unreasonable to envisage the Saudis looking for partners to help start laying the groundwork for commercialisation of LENR within the Kingdom and for export overseas.

Nije čudo što CF/LENR polako dobiva zeleno svjetlo od političkih krugova, sad kad su i naftaši spremni da se prešaltaju i zadrže monopol u proizvodnji energije.


Tragično u cijeloj priči je to što smo CF reaktore mogli imati prije gotovo tri desetljeća, izbjeći kurenje ogromne količine fosilnih goriva, i drastično ublažiti nastupajuće klimatske promjene i devastaciju biosfere, samo da nije proklete ljudske nezasitne pohlepe.
Ratove zbog nafte da i ne spominjemo.
