Thorium Remix 2009 - LFTR in 16 Minutes

http://thoriumremix.com/2012/#download Thorium is readily available & can be turned into energy without generating transuranic wastes. Thorium's capacity as nuclear fuel was discovered during WW II, but ignored because it was unsuitable for making bombs. A liquid-fluoride thorium reactor (LFTR) is the optimal approach for harvesting energy from Thorium, and has the potential to solve today's energy/climate crisis. This 16 minute video summarizes 197 minutes worth of Google Tech Talks on the subject of Thorium & LFTR. Source material... The Liquid Fluoride Thorium Reactor: What Fusion Wanted To Be http://www.youtube.com/watch?v=AHs2Ugxo7-8 Aim High: Using Thorium Energy to Address Environmental Prob http://www.youtube.com/watch?v=VgKfS74hVvQ Energy From Thorium: A Nuclear Waste Burning Liquid Salt Thorium Reactor http://www.youtube.com/watch?v=AZR0UKxNPh8 This edit was created back in 2009, when the best video resources available on the subject were Google Tech Talks. Since then I've shot numerous lectures on the subject and created a higher quality summary. Please help propagate the newer version... http://www.youtube.com/watch?v=P9M__yYbsZ4 ...so that people might find it before this older resource.

With the potential of wireless transmission of electricity, it's entirely plausible that one day we could recharge electric vehicles as we drive on the road, (:

Perhaps I should stop playing with solar panels (my favorite) because people who make them drive multi ton projectiles that can also cause one to die and which convert hydrocarbons to XSCO2 exactly as was spewed by hyper volcanism millions of years ago which caused excess acidity of the oceans that grew cynobacteria that fowled the very air we breath, causing dieoffs similar to what will happen AGAIN because we are afraid of a nuclear reaction that can power planetary civilizations...LFTR!

LFTR was not a ...
LFTR was not a breeder, well, perhaps, just barely. Why would anyone denounce a proven source of energy way better than anything else? So if it has some "hot spots" so what... Not like it will devastate entire countrysides just because of an unforeseen event! Thus, a radioactive room (whether caused by such unforeseen event or not) is FAR less damaging than its XSCO2 counterpart, too.

Thanks so much for your hard work. By the way, I think nobody here would miss Matrix29bear's trolling if you blocked him. Any idiot can quote mine shit off google to support a point of view, no matter how misinformed and stupid it is!

GOOGLE[ Fluoride ] ...
GOOGLE[ Fluoride ] Pure fluorine gas may be stored in steel cylinders where the inside surface is passivated by a metal fluoride layer that resists further attack. Passivated steel will withstand fluorine provided the temperature is kept below 200 °C (400 °F). Above that temperature, nickel is required. Regulator valves are made of nickel. Fluorine piping is generally made of nickel or Monel (nickel-copper alloy).

GOOGLE[ Liquid ...
GOOGLE[ Liquid fluoride thorium reactor ] GOOGLE[ Fluoride ] Reactions with fluorine are often sudden or explosive. Many generally non-reactive substances such as powdered steel, glass fragments and asbestos fibers are readily consumed by cold fluorine gas. Wood and even water burn with flames when subjected to a jet of fluorine, without the need for a spark. Fluorine forms compounds, fluorides, with all elements except neon and helium. Alkali metals react with fluorine violently.

@gordonmcdowell - " ...
@gordonmcdowell - "NOPE! A lot of the arguments against LFTR can be quite interesting, although they're always debatable" Uh, so Fluoride somehow, magically, does not become elementally caustic at 700 ºF? Oh and of course, free neutrons in a small scale nuclear reactor won't create highly explosive Fluoride compounds or spot points of high temperatures because happy little magic bunnies will always intervene to prevent that? Since most built Breeder Reactors have been shut down, no worries.

In case anyone thinks I created a Matrix29bear account to make people arguing against LFTR look crazy... NOPE! A lot of the arguments against LFTR can be quite interesting, although they're always debatable (the ones I've heard). But for every interesting discussion there's a dozen Matrix29bear.

Hydrogen fluoride ...
Hydrogen fluoride gas is a severe poison that may immediately and permanently damage lungs and the corneas of the eyes. Aqueous hydrofluoric acid is a contact-poison with the potential for deep, initially painless burns and ensuing tissue death. By interfering with body calcium metabolism, the concentrated acid may also cause systemic toxicity and eventual cardiac arrest and fatality, after contact with as little as 160 cm2 (25 square inches) of skin.

And people WILLINGLY (with the help of genocidal liars) drink that crap and rub it on their teeth. GOOGLE[ Fluorine - the gas of Lucifer ] The fluorine reacts with water vapour in the air, forming hydrogen fluoride and ozone. A nasty combination.

And yes, what ...
And yes, what happens next is just what you think happens: you run a mixture of oxygen and fluorine through a 700-degree-heating block. "Oh, no you don't," is the common reaction of most chemists to that proposal, ". . .not unless I'm at least a mile away, two miles if I'm downwind." This, folks, is the bracingly direct route to preparing dioxygen difluoride, often referred to in the literature by its evocative formula of FOOF.

Streng had to give ...
Streng had to give up on some of the planned experiments, though. Sulfur compounds defeated him, because the thermodynamics were just too titanic. Hydrogen sulfide, for example, reacts with four molecules of FOOF to give sulfur hexafluoride, 2 molecules of HF and four oxygens & 433 kcal, which is the kind of every-man-for-himself exotherm that you want to avoid at all cost. The sulfur chemistry of FOOF remains unexplored, so if you feel like whipping up a batch of Satan's kimchi, go right ahead.

[continued] red phosphorus (not good), bromine fluoride, chlorine trifluoride (say what?), perchloryl fluoride (!), tetrafluorohydrazine (how on Earth. . .), and on, and on. If the paper weren't laid out in complete grammatical sentences and published in JACS, you'd swear it was the work of a violent lunatic. I ran out of vulgar expletives after the second page. A. G. Streng, folks, absolutely takes the corrosive exploding cake, and I have to tip my asbestos-lined titanium hat to him.

Matrix29bear on 2012-04-16
And he's just ...
And he's just getting warmed up, if that's the right phrase to use for something that detonates things at -180C (that's -300 Fahrenheit, if you only have a kitchen thermometer). The great majority of Streng's reactions have surely never been run again. The paper goes on to react FOOF with everything else you wouldn't react it with: ammonia ("vigorous", this at 100K), water ice (explosion, natch), chlorine ("violent explosion", so he added it more slowly the second time) [continued]

"Being a high ...
"Being a high energy oxidizer, dioxygen difluoride reacted vigorously with organic compounds, even at temperatures close to its melting point. It reacted instantaneously with solid ethyl alcohol, producing a blue flame and an explosion. When a drop of liquid 02F2 was added to liquid methane, cooled at 90°K., a white flame was produced instantaneously, which turned green upon further burning. When 0.2 (mL) of liquid 02F2 was added to 0.5 (mL) of liquid CH4 at 90°K., a violent explosion occurred."

You might also want to GOOGLE[ FOOF Things I Won't Work With: Dioxygen Difluoride ] Elemental fluorine has commanded respect since well before anyone managed to isolate it, a process that took a good 50 years to work out in the 1800s. (The list of people who were blown up or poisoned while trying to do so is impressive). And that's at room temperature. At 700 freaking degrees, fluorine starts to dissociate into monoatomic radicals, thereby losing its gentle and forgiving nature.

Only problems are the issues that Fluoride eats everything. Fluoride gas is bone-destroying toxic. Breeder reactors also tend to destroy themselves too (because of the toxic caustic fluoride).

Im sorry but Thorium isnt as dangerous as you make it out to be. If they are then they wouldnt have been used for Welding wont they? or Engines... or Laboratory equipment or even Wire coating... Heck even Lanterns have them. And Thorium reactors dont produce Th-232... they use them up. And usually The longer the half-life of an element, the less radioactive it is, since its basically stable.

Have you guys checked out the free piston stirling engine design that the people at Sunpower us in their Biowatt electric generator design. Seems like it would be a good fit with these molton salt reactor ideas. Might end up with a nuke reactor in the basement like Ike promised in the nifty fifties. I like Ike!

U233 is a much better material for nuclear weapons than U235. The primary defense mechanisms of LFTRs against proliferation by rogue governments would be a breeding ratio of very close to 1.0 and the inherent U232 poisoning requiring very costly isotopic separation. Terrorists are even worse off, because in addition to the above, they first have to steal 700C, highly toxic (Be) and radioactive fuel salt.
