Is it possible to creating electricity using Gamma radiation and Carbon Nanotubes?
While it is possible, you would need a very high-flux, non-explosive source of gamma rays, which has a net positive output of energy relative to energy you pour into the system. This can be done if and when fusion reactors are finally developed. So far, the only human-created fusion devices are thermonuclear bombs (or hydrogen bombs). Controlled fusion is still tantalizingly beyond our reach. As for carbon nanotubes, those are not a source of energy, but may end up as a useful part of fusion technology.
