Thinking about #LLNL and the fusion setup. The chamber was the size of a pencil eraser, the pellet the size of a BB.
And it generated more energy that the Giant #Lasers spent bombarding it! Amazing.
#Fusion can't 'run away', doesn't leave radioactive material behind.
I kind of wish I could have been there.

Energia pulita senza fine! L’esperimento riuscito di fusione nucleare del Lawrence Livermore National Laboratory

Recentemente, il Dipartimento dell’Energia degli #statiuniti ha annunciato che i #ricercatori del Lawrence Livermore National Laboratory (#LLNL) ha effettuato una scoperta sensazionale. Hanno trovato un modo in cui viene generata più #energia da una reazione #termonucleare inerziale di quanta ne sia stata spesa per la sua creazione.

Massimo Luciani - The National Ignition Facility (NIF) produced more energy than that used from nuclear fusion:

Die Zukunft der #Kernfusion liegt immer noch in der Zukunft

Die Fusionsforscher des großen US-Labors #LLNL machen das, was sie am besten können: Erfolge vermelden. Doch der »Durchbruch« ist nur ein Fortschritt, auf den noch viele weitere folgen müssen
http://www.spektrum.de/kolumne/die-zukunft-der-kernfusion-liegt-immer-noch-in-der-zukunft/2090292

Spoiler: no, non hanno "prodotto più energia di quella consumata"

Ma è comunque un esperimento estremamente importante, anche se non per i motivi che vi ha raccontato la stampa

* 2.05 MJ of #laser #energy in
* 1.25 MJ of #fusion energy produced

but
300 MJ were needed to produce the laser beam in the first place

This seems to be the summary of the #LLNL #LawrenceLivermore #breakthrough -

"“You’ll need gains of 30 to 100 in order to get more energy for an energy power plant,” Dr. Herrmann, program director for weapons physics and design at the Livermore, said."

#Fusion power is always 40 years away from any practical utility. The announcement the week from #LLNL doesn't change that. It's still 40 years away. If you're not convinced, just read the details of the lab setup they used, and ask yourself how to turn that into a practical power source. It will still be 40 years away, long after the point when we need to cross the net zero threshold.

@Eh__tweet io l'ho vissuta come una notizia propagandistica per esaltare capacità bellica degli usa.
La notizia arriva dalla #LLNL che si occupa di biosicurezza, lotta al terrorismo, difesa nazionale, intelligence, scienza, armi e non proliferazione #nucleare.
Giusto per mettere le cose in prospettiva, i francesi con ITER, sono riusciti ad avere un output energetico maggiore dell'input per 17 minuti. Questi qui ce la fanno per un miliardesimo di secondo e la chiamano rivoluzione.

USA e getta.

I worked as a lowly technician at #LLNL (or #LLL because the gov't did NOT want "radiation" in the name). I worked on the #CTR project (ex- #Plowshare) trying to get Controlled Thermonuclear Reactions to appear in a giant magnetic bottle.
#Fusion and #fusionenergy were the goal, but we were told that if we -did- manage a reaction, the cement blocks that surrounded the chamber would not protect us from the radiation.
Can I say I was scared? But I really wanted it to work.
Yay Lab!

LLNL - It’s only natural: separation and purification of rare-earth elements by microorganisms:

@tindall Density isn't everything, and there are many other elements to be considered. But as a single point of intervention, it's probably the least-cost / highest-benefit route.

Vastly more effective than pushing the individual-responsibility canard.

@tindall Other energy uses also derive from land-use.

With denser urban regions:

• Per-unit heating and cooling costs are decreased (shared walls -> reduced heating/cooling loads.
• Communal foodservice. Whether informal or commercial foodservice, meal prep and production occurs at scale. (The low-ooccupancy unit, highly-appointed kitchen is a recent novelty. Earlier times had larger multi-generational houses, rooming-homes, public houses (pubs) for food, village ovens, etc.) The space allocated in residences to food storage, prep, cooking, and cleanup is substantial.
• Infrastructural efficiencies. #StrongTowns discusses this aspect at length.

@tindall And some modes are notably efficient. Ships and trains, by units of mass*distance/fuel are phenomenally efficient, up to 500 ton-miles/gallon for rail, perhaps double that for marine or canal shipping.

Trucks are much less efficient but far more flexible. And passenger cars are comparatively abysmal.

With bulk cargo, scale again matters. Endpoint distribution is hard (the last-mile problem). Rural delivery is similarly difficult (package-delivery services love the high-margin urban areas, but defer to national postal services for rural delivery, typical of any networked-distribution system: mail, electricity, POTS telephony, cellular telephony, broadband internet, retail chains, ...).

The biggest impact of the automobile has been on land-use patterns.

@tindall
The major modifiable elements are transport and discretionary energy use. Transport (about 25% of net energy) is about 70% private passenger, 30% bulk cargo. Modes matter.

The biggest determinant of transportation energy use isn't vehicles or modes, it's land use.

If you spread things out, you need to move things around. A lot. Density also enables and disables numerous transportation modes. Most especially, high-capacity transit (heavy rail, high-speed rail, light rail, busses, trollycar / trollybus) all rely on high concentrations of residences, workplaces, commerce, and industry.
