There has been much discussion of the prospect of developing industrial power from the nuclear fission of uranium. This problem is enormously more complicated than the utilization of solar energy. . . . [W]hereas the solar radiations have been made harmless by natural forces, the artificially induced radiation retains all of its virgin malignity. Whereas the generation of solar energy presents no problem for us, the generation of nuclear energy from uranium is beset with dozens of very serious problems.Whereas solar energy is essentially perpetual, the supplies of uranium are definitely limited.
