Pokracujuc v ukazovani svetla na konci tunelu, upokojovani vystrasenych spolukyberanov obavajucich sa o buducnost ludstva, poukazujem na dobre spravy v oblasti energetiky:

Lockheed Martin claims it has made a significant breakthrough in the creation of nuclear fusion reactors. The company says it has proved the feasibility of building a 100MW reactor measuring only 7 feet by 10 feet. They say the design can be built and tested within a year, and they expect an operational reactor within a decade. The project is coming out of stealth mode now to seek partners within academia, government, and industry. "Lockheed sees the project as part of a comprehensive approach to solving global energy and climate change problems. Compact nuclear fusion would also produce far less waste than coal-powered plants, and future reactors could eliminate radioactive waste completely, the company said."

trolom odporucam hlavne clanok http://aviationweek.com/technology/skunk-works-reveals-compact-fusion-reactor-details kde su detaily, kedze ruku do ohna za vyssie uvedene summary nedavam.

Meanwhile crude oil @ $80

Z oficialnej tlacovej spravy Lockheedu:

“The smaller size will allow us to design, build and test the CFR in less than a year.”
After completing several of these design-build-test cycles, the team anticipates being able to produce a prototype in five years.

Takze zatial nemaju nic rukolapne, len teorie.

000008660155157501303683077311640773566407736284

kebyze sa bavime o nejakej neznamej firmicke tak by sa to dalo brat ako vaporware ale pri lockheed martin?
inak aby bolo jasne, nebavime sa o chladnej fuzii ak si to nahodou pleties s tym... tu sa bavime o v podstate normalnom jadrovom reaktore, to nie je teoria. teoria je maximalne len ako sa to velmi da skalovat, spravit bezpecne atd - tam sa da diskutovat...

inak takyto gigant ked napise ze prvy test bude o rok - tak to je v podstate v takmer nulovom case...

00000866015515750130368307731164077356640773628407737002

Ved si precitaj co sami pisu: "After completing several of these design-build-test cycles, the team anticipates being able to produce a prototype in five years."

Takze prvy realny test bude o 5 rokov, nie o rok.

0000086601551575013036830773116407735664077362840773700207737180

neviem o com sa tu vobec bavime, si precitaj povodny moj prispevok kde som boldom napisal: they expect an operational reactor within a decade.

00000866015515750130368307731164077356640773628407736993

kebyze sa bavime o nejakej neznamej firmicke tak by sa to dalo brat ako vaporware ale pri lockheed martin?

lokheed martin su ti isti co slubili do 10 rokov plne produkovat bojaschopne superlietadlo pouzitelne na vsetky misie za zlomok ceny F22. Teraz, 15 rokov neskor, sa z toho stali 3 rozlicne lietadla, z ktorych stale este len testuju prototypy a plnu produkciu momentalne odhaduju na 2019. A ceny budu minimalne dvojnasobne.

inak takyto gigant ked napise ze prvy test bude o rok - tak to je v podstate v takmer nulovom case...

nie prvy test reaktora, len prvy test nejakeho ich konceptu. Prvy test reaktora odhaduju za 5 rokov ked podla nich budu mat prototyp.

Mozno naozaj na nieco prisli, ale je este priskoro jasat.

ako som uz predchvilou reagoval v paralelnom vlakne a napisal v povodonom prispevku: they expect an operational reactor within a decade.

od zaciatku sa bavime o buducnosti 10 rokov - ja osobne povazuje za uspech ak to bude za 10 rokov, kludne aj 20 rokov. dovtedy to este utiahneme aj na sucasnych technologiach.

000008660155157501303683077311640773566407736284077369930773718807737213

To je problem s termonuklearnou fuziou, ze uz asi 60 rokov bude o 20 rokov v prevadzke, tito a zopar dalsich firiem sice teraz tvrdia ze uz o 10 (mozno potrebuju predat nejake akcie svojej firmy s lepsou cenou), ale funkcne zariadenie schopne sustavne vyrabat energiu s kladnym vysledkom este nikto nevyrobil a nie je AFAIK ani len blizko. V pripade stiepnych reaktorov to od postavenia prveho funkcneho (1942) po postavenie a spustenie prveho dodavajuceho elektrinu do siete (1954) trvalo 12 rokov. Fuzne reaktory sa stavaju snad od 50.-60. rokov a stale nic.

Meanwhile vietor fuka a slnko svieti.

tito ludia zjavne trdia ze su blizko. preto som sem ten clanok dal.

Ved ok. Tu je zopar dalsich: http://nextbigfuture.com/2014/10/updated-prospects-for-commercial.html

Musim priznat, ze potencial to ma riadny. Pekne popisane to je tu: Obnoviteľné zdroje energie - s chladnou hlavou od strany 188
Ale:
Uz vidim tie vladne dotacie, ktore by isli do tych novych bezpecnejsich jadrovych reaktorov.
Navyse to podporuje zavislost od dovozu paliva.
Plus jadrovy odpad.

Preco radsej nepodporit male decentralizovane druzstva, ktore okrem energetiky zabezpecia aj vacsiu sebestacnost? Peniaze tak ostanu u ludi a nepojdu velkym transnacionalnym korporaciam do danovych rajov.
Toto nie je vizia, ze za 10 rokov to mozno bude fungovat. Toto je sucasna realita u nasich zapadnych susedov: K energetickej nezávislosti cez energetické družstvá

000008660155157501303683077311640773177807732853

ja som urcite za decentralizaciu. ak by sa vedeli spravit bezpecne jadrove elektrarne v malom, navyse ako naznacuju postupom casu by to mohlo byt bez odpadnu, tak by to len tu decentralizaciu podporilo a nemuseli by sa stavat obrovske reaktory - no uvidime ako sa bude darit...

00000866015515750130368307731164077317780773285307732898

Bezpecne jadrove elektrarne mi pridu ako oxymoron (najma po Fukushime).

Preco jadrove reaktory a nie obnovitelne zdroje energie ako mala biomasa, male vodne elektrarne a solarne panely na strechach budov? Kam s jadrovym odpadom? Preco byt zavisly od dovozu uranu? Preco investovat do zariadeni, ktore nemozno vymenit rentabilne najblizsich 50-60 rokov?

Akurat citam, ze veterna energia je lacnejsia ako plyn, jadro a uhlie, ak sa zapocitaju externality: http://www.theguardian.com/environment/2014/oct/13/wind-power-is-cheapest-energy-unpublished-eu-analysis-finds?CMP=EMCENVEML1631

tak skusim copy-paste z clanku:

Lockheed estimates that less than 25 kg (55 lb.) of fuel would be required to run an entire year of operations. The fuel itself is also plentiful. Deuterium is produced from sea water and is therefore considered unlimited, while tritium is “bred” from lithium. “We already mine enough lithium to supply a worldwide fleet of reactors, so with tritium you never have too much built up, and that’s what keeps it safe. Tritium would be a health risk if there were enough released, but it is safe enough in small quantities. You don’t need very much to run a reactor because it is a million times more powerful than a chemical reaction,” McGuire notes.

Although the first-generation reactors will have radioactive parts at the ends of their lives, such as some steel elements in the shell, McGuire says the contamination situation “is an order of magnitude better” than that of contemporary fission systems. “There is no long-lived radiation. Fission reactors’ stuff will be there forever, but with fusion materials, after 100 years then you are good.” Contamination levels for fusion will improve with additional materials research, he believes.

I don't think you know what troll means

gramatika? huh, what?
