  The main purpose of this work is to shed light on the possibility of producing huge amount of energy based on the construction matter-antimatter plasma in a molecular crystal. It is assumed that two beams of isothermal hydrogen and antihydrogen are injected into a palladium crystal leading to a plasma state composed of particles and antiparticles. The collapse of this state releases a huge amount of energy which can be used as fuel for space shuttles. Thus, the novel system of isothermal pressure interaction enhances the energy power carried out by the quantum ion acoustic soliton (QIAS). In addition to the energy power released from the particle-antiparticle annihilation. The probability of merging the energy from these two cases is available at certain condition. The released energy may be a significant step in solving the energy scape of Tokomak to produce fusion energy. The study starting from the one-dimensional quantum hydrodynamic model (in which the term of electron-positron and proton-antiproton for hydrogen-antihydrogen is included), a Korteweg de Vries equation (kdv) is derived, the QIAS energy experiences and the annihilation energy power are calculated. It is found that the total energy of QIAS and the energy resulting from hydrogen-antihydrogen annihilation are important step towards the establishment of a cold fusion power station.

Introduction</title><p>Antihydrogen, an atom composed of an antiproton orbited by a positron, was created at CERN in 1995 [<xref ref-type="bibr" rid="scirp.113417-ref1">1</xref>]. Fundamental development of the physics of particle-antiparticle interaction at low energy was achieved by the ATHENA GROUP at CERN in 2006 [<xref ref-type="bibr" rid="scirp.113417-ref2">2</xref>]. It was proved for the first time that the collision of a proton with an antihydrogen leads to the formation of a bound state composed of a proton and an antiproton, (identified by the Authors as antiprotonic hydrogen and known also as protonium), in which both particles are rotating around each other. The binding energy of the antiprotonic hydrogen was calculated as Es = −0.75 keV and the lifetime is τ ~ 1.0 &#215; 10<sup>−6</sup> s. Formation of protonium ions was theoretically confirmed by Abdel-Raouf [<xref ref-type="bibr" rid="scirp.113417-ref3">3</xref>]. Cold fusion based on matter-antimatter interaction was proposed and studied by Abdel-Raouf [<xref ref-type="bibr" rid="scirp.113417-ref4">4</xref>] [<xref ref-type="bibr" rid="scirp.113417-ref5">5</xref>] [<xref ref-type="bibr" rid="scirp.113417-ref6">6</xref>]. On the other hand, the last few years have shown a great deal of interest devoted mainly to the dynamics and applications of plasmas [<xref ref-type="bibr" rid="scirp.113417-ref7">7</xref>].</p><p>An interesting application will be announced in this article in which ion acoustic solitons (IAS) are formed in a compound plasma system of hydrogen and antihydrogen. The study of analog of IAS, using a simplified hydrodynamic model was previously achieved [<xref ref-type="bibr" rid="scirp.113417-ref8">8</xref>]. Since that, there has been a renewed interest in plasmas, covering different plasma modes, instabilities, and other nonlinear effects [<xref ref-type="bibr" rid="scirp.113417-ref9">9</xref>] [<xref ref-type="bibr" rid="scirp.113417-ref10">10</xref>] [<xref ref-type="bibr" rid="scirp.113417-ref11">11</xref>]. The most important quantities in our study are phase velocity, amplitude, and width, and the existence conditions of IAS. Considerable attention will be paid to the possible role; these quantities may play in the energy carried by the IAS. Let us recall that the interacting solitons may split, fuse, and exchange energies during their collisions. Many investigations have been made of the soliton energy for different plasma situations [<xref ref-type="bibr" rid="scirp.113417-ref11">11</xref>].</p><p>The large-scale oscillations are termed “solitons” [<xref ref-type="bibr" rid="scirp.113417-ref12">12</xref>]. IAS are nonlinear and coherent plasma structures that qualitatively share many properties with the low-frequency ﬂuctuations we have measured in the system of high energetic plasma of hydrogen-antihydrogen collision [<xref ref-type="bibr" rid="scirp.113417-ref13">13</xref>]. Solitons propagate in plasma near the ion acoustic speed, they are coherent and can be periodically excited. In a departure with previous linear perturbation analyses of electron-positron collision, we propose that the generation of IAS may be the source of coherent low frequency oscillations. Thus, IAS are coherent plasma oscillations born out of a balance between the nonlinearity of convection and wave dispersion. These waves have been studied extensively both experimentally and theoretically since the 1960s in double plasma devices [<xref ref-type="bibr" rid="scirp.113417-ref14">14</xref>] [<xref ref-type="bibr" rid="scirp.113417-ref15">15</xref>] [<xref ref-type="bibr" rid="scirp.113417-ref16">16</xref>]. To interpret these trends, we note that previous studies have shown that similar types of coherent structures propagating concurrently with ion acoustic solitons (IAS) energy. In the present work, we first review the relevant theory of IAS. We then interpret our proposed experimental measurements of hydrogen-antihydrogen collision through within the lines of this analytical theory to obtain the average value of the energy. On the other hand, in particle physics, annihilation is the process that occurs when a particle collides with its respective antiparticle to produce electromagnetic radiation, such as an electron colliding with a positron to produce two photons. High energetic electron-positron collision (more than 209 GeV) may lead to the production of particle-antiparticle pairs of larger masses, which is the basic concept of the LEP collider [<xref ref-type="bibr" rid="scirp.113417-ref16">16</xref>] [<xref ref-type="bibr" rid="scirp.113417-ref17">17</xref>] at CERN composed of a circular collider the circumference of which is 27 km. The last decade has shown the establishment of the large hadron collider (LHC) based on high energetic proton-proton collisions occurring in a tunnel with 50-kilometer circumference [<xref ref-type="bibr" rid="scirp.113417-ref17">17</xref>] [<xref ref-type="bibr" rid="scirp.113417-ref18">18</xref>].</p><p>In our study, we will focus on the formation of electron-positron and proton-antiproton plasma prior the annihilation process when two thermalized beams of hydrogen and antihydrogen are injected in a palladium crystal, (see Appendix A). The released energy will be calculated and added to the fusion energy of these two fundamental atoms. Apart from this introduction, the content of this paper is distributed in other three sections. The next section deals with the mathematical model employed for describing the plasma state. Section 3 is devoted to results and discussion of our calculation in addition to the anticipated hydrogen-antihydrogen fusion energy. In Section 4 we present the main conclusions drawn from our investigations. The paper ends with the complete list of references mentioned in the text as well as two Appendices A and B, the first of which deals with the main features of palladium crystals.</p></sec><sec id="s2"><title>2.

The amount of energy in case of macroscopic study of the plasma energy is the same in case of free space and palladium crystal. By, changing the velocity of antiproton up to the ion Bohm acoustic wave we could control the amount of energy released from the system. At high speed, the energy of the plasma is very high and within time scale 0.11 s the amount of energy decay very fast. At very low velocity the energy very low but the system is more stable.</p></sec><sec id="s6"><title>6. Total Energy Released from the Proposed Annihilates Mechanism</title><p>As we know the electron-positron pair annihilates into two gamma photons the total energy of which is 1.022 MeV. Also, the protonium annihilation yields energy of the order of 2 &#215; 0.938, i.e. 1.876 GeV. Thus, it is anticipated that the yield of the hydrogen-antihydrogen system is 1886.22 MeV (=3.02205748 &#215; 10<sup>−13</sup> Joule). Which means that we have 3.02205748 &#215; 10<sup>−13</sup> &#215; 6.02214 &#215; 10<sup>23</sup> = 18.1992532386 &#215; 10<sup>10</sup> Joule/mole = 1.882 &#215; 10<sup>16</sup> Joule/kg.

Conclusion</title><p>The one-dimensional hydrodynamic model of linear and nonlinear analyses in the term of electron-positron and proton-antiproton are studied. The linear analyses show a positive root that indicates ion-acoustic waves in the system and the possibility of existing soliton waves. Also, we obtain the calculations of the nonlinear analysis of the deformed kdv equation and the energy released of the formed plasma. The results show that the lifetime of formed plasma increases inside the palladium crystal 13.7 times concerning the free space. We have the same energy of formed plasma in the case of free space and palladium crystal. The renormalized example study assumes that when the velocity of the antiproton is around the ion-acoustic wave the released energy of the plasma could be reached to 1.15723 &#215;10<sup>20</sup> J/mole. On the other hand, if the velocity of the anti-proton decreases, the total energy of the plasma system decreases. This result supports very much the conclusion that we suggested model for obtaining huge amount of energy by constructing a plasma state between thermalized hydrogen and antihydrogen in molecular crystals with approximate velocity less than the velocity of ion acoustic wave of the system. This energy could find interesting application in cold fusion and building up engines for space shuttles.</p></sec><sec id="s8"><title>Conflicts of Interest</title><p>The authors declare no conflicts of interest regarding the publication of this paper.</p></sec><sec id="s9"><title>Cite this paper</title><p>Abdel-Raouf, M.A., Elgendy, A.T. and Youssef, A.A.A.-R.
