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.

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.

Very cool, I was looking around for Nuke powered Car and came across this. Very Cool!

@ufoengines Please see THORIUM REMIX 2011 for fresher video. Most thorium enthusiasts consider power grid reactors charging electric car batteries a far more viable scenario than the "thorium car" stories.

Thorium Reactors: radioactive for 14 billion years

Thorium Reactors need to operate:

- uranium‐235 (U‐235) or plutonium‐239

Thorium Reactors produce:

- uranium‐233 – is as effective as plutonium‐239 for making nuclear bombs

- technetium‐99 (half‐life over 200,000 years)

- thorium‐232 (half‐life:14 billion years)

@Tekknorg "Thorium Reactors: radioactive for 14 billion years". You mean like THE ELEMENT thorium? Present in the Earth's crust? The decay heat powering mantle circulation and thus generating the Earth's magnetic field throughout the existence of our planet? That's not very radioactive, and not-at-all created by the reactor. U-233 makes for crappy weapons material due to easy-to-detect gamma ray emissions from U-232 (present with U-233). There's a REASON why U-233 is not used in today's weapons.

@Tekknorg Thorium doesn't need to be mined, it is already mined as a by-product of rare earth extraction. Currently in North America it is then (by law) disposed of as radioactive waste. In China it is stored for future use as fuel in LFTR/MSR. U-232 would be created, and consumed in the reactor. STAY OUT OF THE REACTOR, is my advice. If the radiation doesn't get you, the 700'C molten salt will.

@Tekknorg "Nothing can hold GASES back." Uh huh.

[Detoyato]

@Tekknorg 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.

they didn't know Yucca was being cancelled

[ufoengines]

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!

This would make a good subject for an episode on "The Big Bang". Get Sheldon behind it, and the deal is closed.

@ryanlak1234 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.

[totoritko]

@Tekknorg You sir are completely unaware of how nuclear weapons are manufactured and of the technological challenges involved. It's not like you can just cut up a UO2 fuel rod (or divert LFTR bred fuel) and put it in a warhead. Making weapons-grade material is DAMN HARD, even advanced countries like Iran are struggling with it. It's way cheaper and easier to make U235 by Uranium-ore enrichment or U238->PU239 (both DAMN HARD) vs. try and extract anything useful from LFTR (CRAZY HARD).

Im pretty sure i seen a program about thorium on the lie-box. It was about the difficulty of getting a reaction from thorium and the difficulty in designing a reactor. Apparently some people say that building a reactor is too difficult and complicated. They then showed a thorium reactor and people trying to get a reaction. They also showed the energy in the reactor and described what they were getting vs what they wanted.

I said it was the Lie-box but i think it was RT. And theyre quite reliable
