  We compute, via numerical simulations, the non-perturbative Coulomb potential
of pure SU(3) gauge theory in Coulomb gauge. We find that that the Coulomb
potential scales nicely in accordance with asymptotic freedom, that the Coulomb
potential is linear in the infrared, and that the Coulomb string tension is
about four times larger than the asymptotic string tension. We explain how it
is possible that the asymptotic string tension can be lower than the Coulomb
string tension by a factor of four.
