Direct nuclear energy conversion system uses nano-hetero-structures that harvest the nuclear particles energy, charging a structure resembling a super-capacitor, that discharges releasing it as electric energy. The nano-structure design uses heterogeneity, in order to create a super-capacitor like structure, generically called “CIci”, where “C” is a conductive layer, made of a material with high electron availability, typically, but not limited to a high Z material, and “c” is a low electron availability material, simply a low Z material, or a combination of such. Specific insulators, also present as nano-layers, separate these two conductive layers. Constructive variants use nano-layers, nano-beads or nano-structures like nano-tubes or nano-wires, each having their particularities. The theoretical energy conversion is very high, but there are various constructive issues that limit the total conversion efficiency. This process determines the maximum power density a structure may provide. Use of fission, fusion or mixed structures (hybrid rectors), provides energy on demand that is much better than the isotopic batteries, where these “CIci” structures might be successfully applied, but the energy depends on the natural decay of the isotopes combination used. The system is in conceptual stage, but shows advantages, making it a strategic importance device.
