  Lately, there has been much interest in high temperature superconductors, and
more recently hydrogen-based superconductors. This work offers a simple model
which explains the behavior of the superconducting gap based on BCS theory, and
reproduces most effects seen in experiments, including the isotope effect and
T_c enhancement as a function of pressure. We show that this is due to a
combination of the factors appearing in the gap equation: the matrix element
between the proton states, and the level splitting of the proton.
