  1. Look into something called "Boxed Sets".

    *sigh*

    The difference engine. Really? Seriously?

    Repeat after me: Ada Lovelace wrote a program for the Analytical Engine architecture.

    I'm sure Babbage's Difference Engine is fascinating, but it can't be programmed. The architecture you're looking for is the Analytical Engine. At least get the basics right.

    Given that the OP merely mentioned that the Difference Engine exhibit at Santa Clara is fascinating, and made no mention of Ada, I'd suggest that your nerd rage is out of control and you need to sit back and take some deep breaths before you next post.

    As several posters have mentioned, the simplest way is to just use the heat to boil water.

    The boiling water part is still non trivial for a fusion reactor because of those pesky magnets you need to keep at rather low temps in order to contain the plasma. I think you may be better off with direct conversion that you mentioned below. And that was the sort of link I was looking for.

  7. Re:can someone please explain for me on Germany Fires Up Bizarre New Fusion Reactor (sciencemag.org) · · Score: 4, Interesting

    Take a look at the specs in TFA. The magnets in this system are cooled with liquid helium to -270 deg C. The plasma sits inside the magnets. Thus any energy extracted from the plasma has to cross the boundary of the magnets, while at the same time not upsetting the magnets themselves.. What I want is an explanation of how this aspect is being considered. Once you have the energy out of the core you can pipe it into turbines to produce electricity. But that part is easily done.

    Same as a fission reactor?
    The cooling system powers steam turbines

    Yes .. but how? The devil is in the details. Are you jacketting the toroid in a cooling layer? or are collecting the energy via another method? (A poster below mentions the drawing off of helium that will be required for continuous operation - no idea if that harvests enough energy to be viable or not)

  9. Re:can someone please explain for me on Germany Fires Up Bizarre New Fusion Reactor (sciencemag.org) · · Score: 1

    That said, for continuously operating toruses you do have to "draw off" the "ash" (helium) by means of an "exhaust" system that juts up into the outer reaches of the plasma stream (where the heavier helium concentrates), which is "a" challenge (the component is subject to a very hostile environment and faces huge thermal loads), but it's not a showstopper challenge by any means.

    So what sort of mass of helium are we talking about? (I have no understanding of the scales involved) and is this a viable way of bleeding off energy? (and if so will that make fusion reactors potentially the worlds best source for helium?)

  10. Re:can someone please explain for me on Germany Fires Up Bizarre New Fusion Reactor (sciencemag.org) · · Score: 2

    Heat. Thermal transfer to steam turbines.

    Standard PWR fission reactors use a 2 stage liquid/steam system to move energy from the core to the turbines. The first stage is flowing the liquid directly over the core inside the reactor vessel, which in turn keeps the reactor vessel at a decent temperature. But you can't do this with a fusion set up due to not being able to get to the inside of the (in this case) toroid. Thus all of the produced energy seems like it has to flow through the toroid walls in order to escape the reactor vessel - which would be rather nasty for any systems in close proximity to that reactor vessel (EG control systems that operate the magnetics and keep the plasma bottled up). So It seems to me that the only practical way of extracting the energy is by dunking the entire reactor vessel in the first stage liquid - and that seems impractical.

    In all of the test fusion reactors I have seen there appears to be no mechanism to draw off the "excess" energy for use in power production. They all seem to be sealed units. So what are the conceptual ideas for taking the energy out from a fusion reactor?

And that can improve the overall bottom line, and hence make it attractive from a financial point of view. As an analogy it can be better financially for companies to lease rather than own the buildings or equipment they use.
