  We calculate the possible interaction between a superconductor and the static
Earth's gravitational fields, making use of the gravito-Maxwell formalism
combined with the time-dependent Ginzburg-Landau theory. We try to estimate
which are the most favourable conditions to enhance the effect, optimizing the
superconductor parameters characterizing the chosen sample. We also give a
qualitative comparison of the behaviour of high-$T_\text{c}$ and classical
low-$T_\text{c}$ superconductors with respect to the gravity/superfluid
interplay.
