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

Click For Summary
SUMMARY

The discussion centers on the energy release of the CNO cycle in carbon fusion, emphasizing the significant temperatures required, ranging from 20 million to 600 million Kelvin. Participants debate the feasibility of constructing a physical CNO cycle reactor, highlighting the challenges posed by bremsstrahlung losses, which can lead to a net energy loss unless the reactor is sufficiently large. The conversation also touches on the current state of fusion technology, noting that advancements have been slower than anticipated, with projections for practical implementation remaining uncertain.

PREREQUISITES
  • Understanding of the CNO cycle in stellar nucleosynthesis
  • Knowledge of bremsstrahlung radiation and its impact on plasma physics
  • Familiarity with fusion reactor concepts, including tokamak and laser technologies
  • Basic principles of thermodynamics and energy transfer in nuclear reactions
NEXT STEPS
  • Research the CNO cycle's energy release calculations and implications for fusion reactors
  • Study bremsstrahlung losses in plasma physics and their effects on energy efficiency
  • Explore advancements in tokamak and laser fusion technologies for potential breakthroughs
  • Investigate the engineering challenges of constructing a physical fusion reactor

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.
