I cannot recall where exactly I found this document. In some respects, the reported results of what is basically a very simple experiment call to mind the work of Ken Shoulders on EVO's - a topic I will return to very soon. In the meantime download this article, read the very bold claims, and if you can add some better links to available sources, please do. The English is not quite perfect, in fact I have made a few edits to the extract below, but the content I found fascinating,
In 1974, the young Belorussian scientist Sergei Usherenko discovered the effect of super-deep penetration of solid micro-particles with a diameter of 1-1000 μm into solid metal barriers (targets) with an anomalous energy release 10 2 ... 10 4 times greater than the kinetic energy of the particle at the time of its Impact on the obstacle with a speed of about 1 km / s. The energy effect was estimated from the energy of burning a micro-particle of a threadlike channel in the thickness of the target. The length of the threadlike channel in the steel reached up to 200 mm and even more. Calculations also showed that the kinetic energy of the particle is sufficient for penetrating the target to a depth of no more than 6-10 diameters of the particle itself. The observed effect is not explained from the standpoint of modern thermodynamics, electrodynamics, the theory of relativity and quantum theory, including quantum chromodynamics (QCD). The source of (animalous) colossal energy in the Usherenko effect was not established.
The energy release in the target channel is estimated at 10 9 ... 10 10 J / kg per particle. This greatly exceeds the energy level of any possible chemical processe. In addition, according to Usherenko, the spectral analysis of target cross-sections (?) and the channels formed by the advent (embedding) of micro-particles in the targets showed the presence of new elements. Also (after exposure) the targets show the presence of Radon gas not originally present in the samples under investigation. X-ray film installed in the target area also showed changes. In some experiments, the nature of the radiation turned out to be ruled (?).
This indicates that the phenomenon of ultra-deep penetration of micro-particles into barriers is associated with complex synthesis (of new elements) and unexplored high-energy physical processes that are characteristic for the physics of elementary particles and the atomic nucleus.
