Strange wikipedia entry about the sun's core

Click For Summary

Discussion Overview

The discussion centers around a Wikipedia entry regarding the energy production in the Sun's core and its implications for creating fusion reactors on Earth. Participants explore the validity of the entry and the feasibility of emulating the Sun's fusion processes.

Discussion Character

  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant questions the accuracy of the Wikipedia entry about the Sun's core, particularly the comparison of its power production density to that of reptile metabolism and compost heaps.
  • Another participant asserts that emulating the Sun is not feasible.
  • A different participant requests clarification on the previous statement about emulating the Sun.
  • One participant points out that small fusion reactors, specifically H-bombs, have been created with much higher power densities than the Sun's core, suggesting that the challenge lies elsewhere.
  • This participant also notes that a practical fusion reactor would utilize prepared fuels like deuterium and tritium, which are more readily fused compared to the processes occurring in the Sun.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility of emulating the Sun's fusion processes, with some asserting it is not possible while others discuss the potential of existing fusion technologies. The discussion remains unresolved regarding the implications of the Wikipedia entry.

Contextual Notes

The discussion highlights uncertainties regarding the accuracy of the Wikipedia entry and the assumptions underlying the feasibility of creating fusion reactors based on solar processes.

This entry on the voice "SUN" in wikipedia is correct? How can this can be possible?
And if this entry is true how can be possible to create a small fusion reactor on the Earth?

the entry is:
The energy production per unit time (power) produced by fusion in the core varies with distance from the solar center. At the center of the Sun, fusion power is estimated by model to be about 276.5 watts/m3,[39] a power production density which more nearly approximates reptile metabolism than a thermonuclear bomb.[40] Peak power production in the Sun has been compared to the volumetric heats generated in an active compost heap. The tremendous power output of the Sun is not due to its high power per volume, but instead due to its large size.

Thanks

We are not going to emulate the Sun.

Could you be more precise?

We've already created small fusion reactors, known as H-bombs, which have a much higher power density, so that's not the problem.

A fusion reactor would use prepared fuel such as deuterium and tritium to allow fusion to take place far more readily than it does within the sun, where these substances have to be built first from fusion between protons.
