Bullet impact induces transmutation in bismuth

Quote from RobertBryant

Of course if one were to ask the DOD if this could happen

with depleted.

The DOD does similar/same ballistics experiment since dozens of years. The transmutation effect is known and always was attributed to hot fusion effects. Te only problem is that physics behind hot fusion is nonsense...

This seems easy and relatively inexpensive to confirm or rebut.

A company called First Light Fusion claims they have achieved inertial confinement fusion by accelerating the sample with a railgun. The website is unclear, but I suppose the sample whacks into a target, similar to the way a bullet does. With conventional inertial confinement the sample is imploded with lasers.

Krivit criticize this claim. I think his reasons are unreasonable:

I do not see any indication that with a commercial version of this the energy overhead would be extremely high, the way it is with tokamak reactors. Railguns have reasonable efficiency as far as I know. They are being developed for use as weapons aboard navy ships, which have only limited amounts of power available.

The power is presumably very high, judging by all those thick cables, but those naval rail guns use less energy per shot than is found in a box of donuts.

They use less energy? Or they impart less energy?

There's gotta be a lotta overhead. They must get hot!

Just asking. I don't know a thing about them. But anyway, I doubt that Krivit's critique is valid, because I don't think the energy overhead would be as extreme as laser inertial confinement. See the lasers shown here:

This source from 1995 says rail gun efficiency is 47%:

https://ieeexplore.ieee.org/document/364679

Abstract: Railgun launchers must be energy efficient to realize use in practical systems, especially mobile applications which require compact power supplies. This paper shows that railgun launcher efficiency has already been demonstrated at 47 percent at launch kinetic energies up to 8 MJ. Improvements in armature performance have made this performance level possible. Foreseeable improvements in armatures and power supply-launcher integration will push launcher efficiencies to at least 66 percent.

I believe it’s use, I don’t know the efficiency, (50% sounds reasonable but they have no doubt improved a lot since 1995).

My point was more that amazing efficiencies aren’t that necessary, as the required joules are fairly easy to come by. 50 MJ is a reasonably large in kinetic terms, but not that much in terms of chemical storage. I guess on-board power limitations might be an issue, but that only affects rate of fire really.

Newton’s 4th Law: There’s no such thing as a perfectly inelastic object, so take the first three laws with a pinch of salt.

Since the 50’s it’s been thought that if you “jerk” something fast enough, the supposed rules don’t apply.

I am resurfacing this thread because the MFMP just published a video of an experimental replication of the high velocity impact of bismuth projectiles, with focus on the finding of elemental transmutations, and the results of elemental analysis through EDX.

Regardless if you agree or not with the hypothesis being shared here, Bob makes a great preamble connecting the work of several researchers to attempt an explanation of why this happens under these circumstances. The experimental replication itself is very well documented and also recorded on video, the impact craters are impressive in their morphological characteristics and the EDX results are also very interesting. I know it’s quite a long video but I watched it in it’s entirety and It was so interesting that time flew.
