  A theory in which 16-dimensional curved Clifford space (C-space) provides a
realization of Kaluza-Klein theory is investigated. No extra dimensions of
spacetime are needed: "extra dimensions" are in C-space. It is shown that the
covariant Dirac equation in C-space contains Yang-Mills fields of the
U(1)xSU(2)xSU(3) group as parts of the generalized spin connection of the
C-space.
