In this configuration, the heat released from each PU due to the cooling of the thermal working fluid (TWF) is efficiently recovered and reused as supply heat for the first PU in the cascade.  Two case studies on the SSPP have been conducted using air and helium as TWFs. The first deals with PUs coupled in cascade operating with closed processes-based Vsp thermal cycles, while the second involves PUs coupled in cascade operating with closed processes-based VsVs thermal cycles.  Following the corresponding analysis of both case studies, significant results were obtained. These results, derived from this preliminary design study, will be applied to the implementation of the disruptive SSPP prototype operating with real gases as working fluids. This allows for a precise and clear understanding of the issue of generating useful work through expansion, contraction, or both.  Moreover, according to the results, the SSPP composed by a group of power units where the efficiency of each power unit operating with air as working fluid only approaches a value of the efficiency of 22%, can exceed 100% of the nominal design power under certain conditions, which supposes a flagrant violation of the principle of conservation of energy due to the fact that such disruptive Self-Sustaining Power Plant is enabled to overcome a Perpetual Motion Machine of second kind.","PeriodicalId":15024,"journal":{"name":"Journal of Advances in Physics","volume":"13 18","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141271222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some studies link them but they are restricted to very limited aspects, as if trying to maintain the independence between them. In Mechanics, energy is considered a single uniform property represented by a scalar magnitude has limited its study. On the contrary, Thermodynamics analyzes each magnitude separately and links them with already different definitions beforehand, this allows these to be given diverse properties often related to the reference systems and subsequently linked to each other a posteriori without losing their particularities. This can be seen in the definition of internal energy and kinetic energy of the volume of gases; In Mechanics, this separation is not made and therefore it is restricted to considering energy as a scalar. This study defines why energy should be subdivided, what advantage comes from analyzing it in this way, what cases it applies to, what answers are obtained that were not achievable before, and it eliminates contradictions that are generated if it is considered only a scalar. This reasoning also opens the way to the introduction of the concept of entropy in mechanics (more precisely in dynamics), which provides answers to the temporal direction of events and, in this way, the false idea of temporal symmetry in the equations is eliminated and it allows us to see that it is presented this way intentionally as a way to simplify problem-solving.","PeriodicalId":15024,"journal":{"name":"Journal of Advances in Physics","volume":"34 23","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140672028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nature of Dark energy (DE) and matter (DM) is enigmatic mystery of the modern astrophysics. This article is a theory establishes the nature and laws of DE and DM forces. They are among the forces controlling the universe harmony and homogeneity. The derived equations were based on the published Sayed quantum gravity force formula. The Sayed`s Dark energy force (SDEF) formulas indicate that they are function in quantum gravity force (FQG), energy density(ρ), cosmological (Ʌ), Hubble (H), and Planck (h) constants. The formulas were verified and validated. For Planck and cosmos scales, the Dark energy force, energy density, and Ʌ were calculated and found to be 2.538x1084 N, 10-26 Kg/m3, and 10-52 m-2 respectively. These values are in high concordance with the declared values. The results obtained show that the DE force represents more than ¾ of the universe forces as the observations. The disputed Hubble constant was also calculated and found to be in the range; ~2.2 x10-18 s-1. It can also be stated and emphasized that the light speed violation (E≠mc2) is a must to solve the DE nature and many other universe mysteries.","PeriodicalId":15024,"journal":{"name":"Journal of Advances in Physics","volume":"121 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140708741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The findings will be applied to the prototyping implementation task, which includes the cascade and series of cascade coupling of several regenerative power units. The empirical results of the case studies provide the data needed to carry out a prototyping task considering the results of real cases subjected to realistic irreversibilities and heat recovery factors that make the self-feeding power plant an interesting design option.

This new relation, based on the quantum uncertainty principle, gives the mass m of any free fundamental particle at its origin, in terms of the inverse cube of its velocity v. This quantitative relation is different and is a negation of the one derived from mechanical-metaphysical (Classical Mechanics or CM) approach since Isaac Newton and its relativistic post-quantum formulation of Albert Einstein. This new mass-energy-velocity relation is in conformity with known knowledge and is appropriately substantiated by the recent reports that “high-energy photons of gamma radiation from a distant galaxy arrived at Earth four minutes after lower-energy photons, although they were apparently emitted at the same time”; and another saying that “the time delays of gamma-ray photons are inversely proportional to their energy”.  These findings would contradict Einstein's theory of relativity, which says that all photons (particles of light) must move at the same speed c. \u0000QD considers matter-antimatter particle pairs in their elementary virtual forms and kinetic motion as an eternal quantum dynamical process of existence and non-existence (Being-Nothing) arising from abstract space and abstract time in a contradiction to each other. The virtual particles can transition to real particles through quantum tunnelling or when equivalent energy becomes available. Any existence in this view is a contradiction; vulnerable to change, motion, evolution, development etc. The aggregation of the elementary particles and their motions mediated by chance and necessity, give rise to the phenomenology of this infinite, eternal and ever-changing universe.  \u0000The CM approach on the contrary is based on epistemology and considers that matter (ordinary + light) and motion have an esoteric origin from the mystery of the single act of creation by God; of a finite universe in the finite past; where the premise of conservation laws and “ex nihilo nihil fit” prevail. In its relativistic version, this approach makes a fundamental difference between ponderable matter and light and in fact question the existence of particulate matter. Two axiomatic assumptions, one by Newton of one-sided universal gravitational attraction and the other by Einstein that the velocity of light c is an absolute and universal constant has brought in unphysical objects and phenomena into scientific discourse leading to century-long confusion and scholastic debates among the physicists; with no end in sight!    ","PeriodicalId":15024,"journal":{"name":"Journal of Advances in Physics","volume":"8 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140260312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
