Somewhat of an old topic, but I see nothing wrong with fission being the main power source for the human race for centuries... once we finally perfect it. A molten salt reactor running on uranium/thorium is a pretty neat idea. Sounds quite safe in theory; no pressurized water, potential for complete actinide consumption, no combustible gas production possible, truly inherent safety.

I have heard the analogy that fusion is so difficult you could have a group of PhD's standing around scratching their heads at it. Fission is so easy you can hire a kid straight out of highschool and he/she can run a fission reactor.

I formerly worked at the LLNL fusion project and found there is no desire to have a "Eureka" moment, as if they are suceesful the money flow will stop.  Harvard claimed it will never work.  The crystals they use to amplify the beam damages to crystals at higher power, while may make an operable continuous firing laser for inertial fusion impossible.  You will notice even on the fictionable tv series "Big Bang Theory" never even discusses inertial fusion as a subject.  Even they limit at what level of fantasy the audience will believe.  The only thing the lab is converting is tax dollars into researcher's salaries.

I read through most of this thread yesterday, you have had an amazing change of heart on the fusion matter since 2009.

Are you ready to come over to our side of the Nuclear Binding Energy Curve?  In the end, you are still raising the binding energy of the nucleons in the fuel.

I was blinded by hope.  Hope is hard to kill.  It is dead in me.  I saw the waste, fraud and abuse on a daily basis.  When I complained once too often I was laid off.  I plan to write a book about the experience.  But none of us will see successful inertial fusion in our lifetimes.  However, if the goal was to make a planet killing death star, we are on our way.

Don't give up hope.  Hope is the flame of youth that motivates us.  Turn this crushing disappointment into another opportunity and work on the Nuclear Renascence.  There is much work to be done to bring the Generation 4 designs to fruition.

I consider the Thorium based fuel cycle to be a true renewable energy source.  This is where I think the future is with nuclear technology.  Could you consider pursuing this technology?

I saw the Bill Gates interview on this subject and it seem very interesting and hopeful.  Especially seeing as how he is willing to invest a ton of money towards these reactors.

   Bill Gates is pro nuclear but he seems to be luke warm to Fusion. He does see promise in nuclear in gereral because as he puts it there has been little inovation in nuclear technology and there is a lot of room for new and promising designs. He has invested in the Traveling Wave Reactor and it's prototype.

Walt Disney LOVED nuclear, and try to buy half ownership of one. Sadly, Walt never built any. Reckon Gates will do the same...

As far as I'm concerned Gates is barking up the wrong tree with the travelling wave reactor. The molten salt reactor is far more promising in my opinion. There is no better reactor to breed U-233 from thorium in the thermal spectrum. It is not just a paper reactor either, it was built by Oak Ridge in the 60's and run for over 10,000 hours. The molten salt program was the main directive at Oak Ridge through those years until it was shut down due to political reasons to focus the nation on pursuing the liquid metal breeder.

China is picking up the slack now. They are claiming that they will have a 2 MWth molten salt cooled reactor using TRISO fuel by 2015 and a similar power molten salt fueled reactor by 2017. I guess we'll see if China can finally do it.

     As we enter 2015, the fusion situation at the Lawrence Livermore national Lab has grown darker. Back into 2013, they claimed a breakthrough and return to the real task the laser was designed for, research into nuclear weapons to ensure they will explode when called upon. They do not even pretend to have on the horizon the fusion process to produce power like nuclear plants. This is so ironic, as all the liberal politicians who are usually anti-military would never have approved the project if all it can do was research and bombs. They did find one use for this $4 billion boondoggle, the film the movie, "Star Trek 'into darkness'" at the lab, kind of symbolizing how Moses, the man in charge,  led our tax dollars into the wilderness to which he will never return. There is one positive

If we could take the laser if she could take the laser into space, and make 1 million copies, like the "death Star," we could destroy the planet.

Practical fusion is a nuncupatory power source totally outside of the current cycopede, due to its tardigradous development; pushed by constant babblement and hopeful illaqueation by fopdoodles..... and you can quote me on that.

Are they conducting research on decontamination by laser at LLNL?
A REM is a REM is a REM
Yea, though I walk through the boundaries of containment, I shall fear no dose, for my meters are with me.  My counters, air sample filters, and smears, they comfort me.

World's Largest Fusion Reactor is About to Switch On

http://gizmodo.com/worlds-most-insane-fusion-reactor-is-about-to-switch-on-1741199892

It took 19 full years to build W7-X. By the end of the month, approval to turn the reactor on is expected to come from Germany's nuclear regulators.

At the Department of Energy, it would roll back funding for nuclear physics and advanced scientific computing research to 2008 levels, eliminate the Office of Electricity, eliminate the Office of Energy Efficiency and Renewable Energy and scrap the Office of Fossil Energy, which focuses on technologies to reduce carbon dioxide emissions.

I don't see an impact to fusion research. The increased budget to physics computing was for nuclear weapons testing and climate modeling. Returning it to 2008 levels leaves lots of money and does not seem to make any difference to fusion.

I read a little different:


http://www.sciencemag.org/news/2017/01/10-questions-rick-perry-trumps-pick-energy-secretary

ITER is a multinational project to prove that generating energy by fusing hydrogen isotopes together at temperatures exceeding those in the center of the sun is scientifically feasible. But the project, currently under construction in southern France, is at least a decade behind schedule and could cost three times original estimates.

If a U.S. domestic project were similarly so far out of control, Congress or the White House likely would have killed it long ago. But the United States has only a 9% stake in ITER—matched by China, India, Japan, Russia, and South Korea—whereas the European Union, as host, is footing 45% of the bill and is determined to see it through.

Attitudes in Congress range from enthusiastic flag waving to vocal opposition. The Senate has repeatedly put forward budgets that zero out ITER, while the House continues the back it. The annual compromise has been to provide only just enough money to remain a partner; but that has squeezed domestic fusion programs to the point of near-extinction.......



reckon we will have to wait and see 2018's budget,... [coffee]

This is a different article and it focuses on France's ITER. It seems the job program for US fusion may still be intact.  ;)
