Nuclear furnace of the Earth

V.F. Аnisichkin, А.А.Bezborodov

It is commonly known that the Sun and other stars get their tremendous energy from the "thermonuclear furnace" burning in their depths. Nevertheless, the comparatively cold Earth also emits much more heat than it could be expected by considering some processes frequently encountered in nature, such as natural radioactive decay. Some scientists believe that the reason for this is the operation of a huge nuclear reactor deep in the Earth. This georeactor, however, is based on chain reactions of fission rather than on thermonuclear synthesis, as in stars
