When two (or more) nuclei fuse to form a heavier element, a known quantity of energy is released. Today, the process seems easy to describe, at least to some degree. The endeavor to construct the devices for fusion energy is great, and there are some experimental ones running the diverse experiments. The proposal now presented is a nanoapparatus. If one could do such a nanodevice, it could be integrated in a wide range of applications once it is possible to consider it portable and able to generate different controllable amounts of energy. The author calls this document, in a broad sense, a conceptual thesis. Mostly, it has natural language as the principal tool. A guide for the calculations was worked to complete the essay, supporting a possible configuration of a nanodevice. This is a kind of a conjecture, a logical but speculative one, that needs to be verified. Like some studies, this one shows first and only its most theoretical content. The author either explicitly or implicitly discusses the space-time fabric, double-slit experiment, and other concepts, like nonduality and indistinguishability. The technology is supported by some established theories or others that have been adapted.
