We discuss the recently published numerical computations of the vortex free energy. They dramatically demonstrate that the excitation probability for a sufficiently thick vortex approaches unity at large beta, i.e. that thick vortices `condense' in the vacuum. This is known to imply confinement. An analytical approach for exploring this phenomenon is also outlined.
