- I have already received several responses to my post saying that there is
- a difference between muon catalyzed cold fusion and the new type of cold
- fusion that uses palladium. I realize this!
-
- However, both types of fusion are based on the idea of getting deuterium
- nuclei close together so that the quantum mechanical probability of them
- ending up in the same place and fusing is increased. In the more common
- approach to fusion the idea is to get the atoms HOT enough that they are
- moving fast enough that some of the nuclei overcome the repulsion from the
- electron cloud and run into each other.
-
- In palladium type of cold fusion some metal is used to bring the deuterium
- nuclei close together. Palladium can hold 1000 to 3000 times its volume
- in deuterium, so the deuterium atoms are as close together as they would
- be if they were under 1000 to 3000 atmospheres of pressure. Since the
- nuclei are closer together and the probability of being in the exact same
- place is increased, thus the increased fusion rate. Its not yet clear to
- me if the palladium is doing more than concentrating the deuterium. Does
- anybody know?
-
- In muon fusion one electron in a deuterium molecule is replaced by a muon
- which is much heavier. This causes deuterium molecule to get about 200
- times smaller. It then takes about 10ee-12 seconds, on average, for the
- nuclei to end up in the same place and fuse. The problem is that it takes
- energy to make the muon, it has a short life, and so far we have only been
- able to get about 150 fusion per muon. If either making muons took less
- energy (its not at all efficient now) or each muon catalysed more
- reactions this could make energy.
-
- It seems that we (and the press) could have been just as excited by muon
- fusion if it had generated energy. Also, we could have ignored the
- palladium type of fusion if it did not sound like it had commercial
- potential. It also seems that what was learned while working on the
- muon type of fusion lead to the palladium type of fusion.
