Supported by the photon cage theory of the unified light-origin field and the fundamental theoretical conclusions from Research on the Measurement of Upper and Lower Critical Energy Thresholds of Free Protons — Based on the Resonance Dissociation Mechanism of Photon Cages, free protons are formed by self-locked high-density gamma photons with triggerable critical saturation dissociation thresholds. Continuous energy storage is realized by inputting high-energy gamma resonant photons matching the inherent frequency band of protons. After breaking the dissociation threshold, the overall photon cage structure of protons collapses, and massive internal gamma photons are released all at once, achieving mass-energy output far exceeding the magnitude of electron-based systems. This mechanism features inherent ultra-high energy gain characteristics. The internal energy storage density of protons is more than one thousand times that of electrons, and the energy released by single dissociation greatly surpasses electron energy systems. Compared with traditional nuclear fission, magnetically confined nuclear fusion and electron mass-energy release paths, proton photon cage dissociation has theoretical advantages including a higher upper limit of output power, larger energy supply scale and stronger potential for sustained energy production. This paper only carries out pure theoretical deduction and forward-looking demonstration of energy systems. Engineering implementation contents such as equipment manufacturing, construction of high-energy gamma light sources and large-scale energy storage devices are not discussed within the scope of this paper. Theoretical derivations indicate that controllable dissociation and energy release of protons are inherent cosmic laws of microscopic photon clusters, which can serve as a theoretical scheme of ultimate ultra-high power energy for industries, power grids and large-scale energy bases.
