What is the energy release of the CNO cycle in carbon fusion?

Click For Summary

Discussion Overview

The discussion revolves around the energy release of the CNO cycle in carbon fusion, with participants exploring the feasibility of constructing a CNO cycle reactor. The scope includes theoretical aspects of the CNO cycle, practical considerations for reactor design, and the challenges associated with fusion technology.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant seeks detailed information about the energy release of the CNO cycle and other relevant details.
  • Several participants reference the Wikipedia page for energy release information but express a desire for more specific insights related to reactor construction.
  • There is a contention regarding the feasibility of constructing a physical CNO cycle reactor, with one participant asserting that it is impractical without a star.
  • Another participant argues that advancements in fusion technology could make such a reactor possible within 5 to 20 years, despite skepticism from others.
  • Concerns are raised about bremsstrahlung losses in plasma and the potential for a net energy loss in a proposed reactor design.
  • Participants express differing views on the timeline for achieving practical fusion technology, with some citing historical challenges in fusion development.

Areas of Agreement / Disagreement

Participants do not reach consensus on the feasibility of constructing a CNO cycle reactor or the timeline for advancements in fusion technology. Multiple competing views remain regarding the practicality and potential energy output of such a reactor.

Contextual Notes

Discussions include assumptions about the required temperatures for the CNO cycle and the implications of bremsstrahlung losses, which remain unresolved. The conversation reflects varying levels of optimism and skepticism about future advancements in fusion technology.

I would like details on CNO Cycle Carbon Fusion about the exact energy release of an entire cycle through the reaction and other details you would think would be important about the CNO cycle.

Physics news on Phys.org
The Wikipedia page gives the energy release, as well as many other details. Do you have specific questions?

Not exactly, I was wanting to try and construct a CNO cycle reactor, what do you think would be some important stuff to know?
 
What do you mean by "construct a CNO cycle reactor"? A physical reactor? Out of the question unless you have a spare star handy. Or do you mean a computer model?

No, a Physical Reactor... I realize that the temperatures required are like 20 million to 600 million kelvin(Proof of Temperature) however it is still a project. Just give me some other important details man...

You must be kidding!

Whatever man, this is why no meaningful discussion can happen on the physics forums, maybe not with current superconductors or plasma heating techniques is this possible however it will be possible within 5 to 20 years, I would assume from the current advancement of human technology in fusion. However that is not the point of this thread, the point of this thread was to gain meaningful information about the CNO cycle.

You have already got the moderator involved for no reason other than to waste his time, so I am sure this post will be banned within hours because of how strict the topic regulations are on this forum.

If you don't think fusion will ever advance to the point that we will be able to contain CNO cycle fusion or sustain it you are a fool, but then some people did back in the 1900s think that the United States Government and Oppenheimer were fools about trying to make a atomic bomb however history proved them fools too. They said such things as, "But you would have to exactly control the fission of a atom" However those people did not have vision as we know today.

Try calculating the bremsstrahlung losses from your plasma and compare that to the energy generated by the CNO cycle. I think you will find that it is a net loss. Unless your reactor is large enough that the bremmstrahlung radiation cannot escape (like in a star), your reactor will have net loss of energy. Don't take my word for it, do the calculation.

Thank you, see that is the type of information I made this thread for.

Possible within 5 to 20 years? Extremely unlikely! Current fusion technology (tokomak or laser) has been promising success for 30 years, since around 1960. They seem to be no nearer.

Yes possibly I won't deny that fusion technology has taken longer than expected by people, however what doesn't, innovation and invention is a thing that takes time.

So, what you are telling me is I would have to heat the water or whatever coolant that produces energy when tossed through a generator with bremsstrahlung and other radiations emitted from the plasma, thank you for this insight.
