Thor

Thorium is a weak radioactive metallic chemical element with the symbol Th and atomic number 90. Thorium is more abundant than uranium, and can satisfy world energy demands for longer. Thorium fuels result in a safer and better-performing reactor core because thorium dioxide has a higher melting point, higher thermal conductivity, and a lower coefficient of thermal expansion. It is more stable chemically than the now-common fuel uranium dioxide.

Thor is a highly genetically modified human, feeding on artificial cosmic light radiation spectrum, generated in a nuclear reactor on thorium fuel. Situated in a mobile self-driving AI next-next-next-generation platform. Vehicle suitable for years of uninterrupted movement, programmed for tracing, capturing and following unique and special cosmic rays piercing our planet from the universe.
