So would we use uranium 235 or do Thorium 232-->U233 as a fuel cycle and would it be safe enough so the public wouldn't object (protest, riots, etc)? I'd am more interested (if doable) with Lead-Bismuth moderated reactors, or Helium using TRISO fuel- https://ceramics.org/ceramic-tech-today/energy-1/silicon-zirconium-nitrides-may-serve-as-superior-coatings-in-next-generation-nuclear-fuels I am hoping your LFTR does the job for pragmatic reasons alone, but wonder if the sticker shock of development cost may push MSR's to the 22nd century?

A prototype was built at Oak Ridge in the '50s as a research reactor prototype for the Air Force proposal to have nuclear powered version of the B-36 that would stay airborne almost continuously so as to be immune to a Soviet first strike. But the project was dropped without ever being turned into a power source. Part of the problem was that only enough shielding could be carried to protect the crew, but the radiation also damages structure. Brent On 6/29/2022 5:50 PM, [email protected] wrote: Walk away safe. Are you two convinced that we have done enough research via chemical engineering? This'd be for corrosion of pipes, and as all us science nerds know sodium itself can ignite in air and explode when exposed to water, which is one reason I like it. But the sodium fluoride is nonflammable. I am still betting on solar and wind as cheaper and faster. I am thinking that getting this boy (LFTR) to market will take the Chinese and Gates 20 years longer to get it all to work correctly. Hence, even though I am a foul Trumpkin, I support the quick and the modular, with batteries and, or, micro-hydroelectric. It is something that dudes with a pickup truck can install and maintain, distributed nationwide & worldwide. Environmentally Safe!

A Liquid Fluoride Thorium Reactor (LFTR) would greatly reduce or eliminate entirely the problems associated with conventional fission reactors; they need some additional research and development before they become practical but vastly less than what would be required for a fusion reactor. I understand Indian is building a prototype LFTR. A molten salt reactor is "walk away safe". Thorium also has the advantage that there is enough already enough for millennia of power as a by product of mining rare earths for magnets. > Nukes may have reduced the great war cycles, but Putin has restarted it > again.

Stalin and Mao Zedong had nuclear weapons and both were monsters, but neither of them ever used one in anger, the fact is the only human being who ever did was Harry Truman, and that was nearly 80 years ago. So I think the human race has a pretty good chance of surviving Putin and Xi. > The societal impact of QC is sketchy to me, as it needs to be conformed to human impacts if it is to be better than conventional? Quantum Computers are well known for their code breaking abilities but that's not all they can do, in the June 9 2022 issue of the journal Science researchers report they have found a quantum learning algorithm that achieves an exponential speed increase over the that of any known conventional algorithm both in predicting how a quantum system, for example an atom or a molecule, changes over time, and also in its ability to extract useful information from noisy input data. It perhaps should be noted that a brain frozen to liquid nitrogen temperatures is bound to contain a lot of noisy data regardless of how carefully it was frozen. This is the abstract of the article: "Quantum technology promises to revolutionize how we learn about the physical world. An experiment that processes quantum data with a quantum computer could have substantial advantages over conventional experiments in which quantum states are measured and outcomes are processed with a classical computer. We proved that quantum machines could learn from exponentially fewer experiments than the number required by conventional experiments. This exponential advantage is shown for predicting properties of physical systems, performing quantum principal component analysis, and learning about physical dynamics. Furthermore, the quantum resources needed for achieving an exponential advantage are quite modest in some cases. Conducting experiments with 40 superconducting qubits and 1300 quantum gates, we demonstrated that a substantial quantum advantage is possible with today’s quantum processors." Quantum advantage in learning from experiments You didn't even mention what most scientist see as the big application for QC, modeling and predicting the interaction of big biological molecules, e.g. protein folding. One of the big motivators for QC way Feynman's talk, "There's Always Room at the Bottom". Brent -- You received this message because you are subscribed to the Google Groups "Everything List" group.
