A few questions about atoms splitting and some about cold fusion

Click For Summary

Discussion Overview

The discussion revolves around the concepts of atomic fusion and fission, particularly focusing on the energy dynamics involved in these processes. Participants explore the implications of energy transfer during fusion and subsequent fission, as well as inquiries into cold fusion and the specific conditions required for hydrogen fusion in palladium.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions the energy implications when an atom is fused and then split, suggesting that energy is not created or destroyed but transferred.
  • Another participant clarifies that fusion of hydrogen into helium results in a loss of mass, which is released as energy, while fission of uranium also results in a mass loss and energy release.
  • It is noted that to fission helium back into hydrogen, energy must be added, and similarly, energy is required to fuse rubidium and cesium into uranium.
  • A participant mentions the need to understand nuclear binding energy in relation to these processes.
  • There is a request for specific data regarding the pressure conditions under which palladium absorbs hydrogen for cold fusion, referencing the work of Pons and Fleischmann.

Areas of Agreement / Disagreement

Participants express various viewpoints on the energy dynamics of fusion and fission, with some clarifications provided. However, there is no consensus on the implications of energy transfer or the specifics of cold fusion conditions, leaving the discussion unresolved.

Contextual Notes

Participants reference specific nuclear reactions and energy requirements without resolving the complexities of these processes. The discussion includes assumptions about energy transfer and the conditions necessary for fusion, which remain unverified.

A few questions about atoms splitting and some about "cold fusion"

Ok first I was thinking, when atoms fuse, they release energy, when an atom is split... it releases energy. Now, since energy is not created nor destroyed but only transferers, if you fuse an atom and then split it again, what will happen when you split it since it lost energy when it was fused?

Then on cold fusion, when pons and fleishman did their estimate on how much atmospheric pressure palladium puts on hydrogen when its absorbed, it was a lot less than nessasary for fusion, does anyone have the exact numbers? such how much pressure they had in the palladium and how much is required for hydrogen atoms to fuse?

Not any atoms.

You fuse hydrogen into helium. The product is slightly less massive than the ingredients. The missing mass is released as energy.


You fission uranium into (say) rubidium and cesium. The two products are slightly less massive than the initial ingredient, and the missing mass is relased as energy.

Conversely,
To fission helium back into hydrogens, you'd have to add energy.
To fuse rubidium and cesium into uranium, you'd have to add energy.

Ohh ok. That makes a lot more sense lol

This forum is freakin awesome.
 
1,1H + 3,1H --> 4,2He loss in mass is = energy released fusion reaction of the nuclei
requires massive activation energy
