A few questions about atoms splitting and some about cold fusion

In summary, the conversation discusses the release of energy when atoms are fused or split. It is mentioned that the total mass of the fused or split atoms is slightly less than the initial ingredients, and the missing mass is released as energy. The concept of nuclear binding energy is also brought up as a factor in fusion reactions.

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
 

1. What is cold fusion?

Cold fusion is a hypothetical process that involves the fusion of atomic nuclei at room temperature, resulting in the release of large amounts of energy. However, it has not been proven to be a viable source of energy and is not currently recognized by the scientific community as a legitimate phenomenon.

2. Can atoms split at room temperature?

No, atoms cannot split at room temperature. Splitting atoms requires a large amount of energy, which is typically achieved through processes such as nuclear fission or fusion. These processes require extremely high temperatures and pressures, which cannot be achieved at room temperature.

3. What is the difference between cold fusion and traditional fusion?

The main difference between cold fusion and traditional fusion is the temperature at which the fusion process occurs. Traditional fusion involves heating atoms to extremely high temperatures (millions of degrees) to overcome the repulsive forces between their positively charged nuclei and fuse them together. Cold fusion, on the other hand, claims to achieve fusion at much lower temperatures (room temperature or slightly above), but there is currently no scientific evidence to support this claim.

4. Is cold fusion a possible source of unlimited energy?

Currently, there is no evidence to support the claim that cold fusion could be a viable source of unlimited energy. While the idea of achieving fusion at room temperature is appealing, it has not been proven to be possible and there are many technical challenges that would need to be overcome before it could potentially be used as a source of energy.

5. What is the current scientific consensus on cold fusion?

The scientific community is generally skeptical of the claims surrounding cold fusion due to the lack of reproducible results and the absence of a plausible theoretical explanation. The majority of scientific studies have been unable to replicate the results claimed by proponents of cold fusion, and as a result, it is not considered a legitimate phenomenon by most scientists.
