Except for the fact of reverse signs for temperature-pressure gradients, there is an uncanny resemblance between the physics of vacuum condensation and the physics of atmospheric condensation. The once and only analogous existence of vacuum evaporation is the existence of naked singularity at time zero and infinite positive pressure and infinite mass-energy density. The reverse vacuum condensation occurs at much lower temperatures which created both mass and energy at higher absolute values of negative pressure.

With this reversal of fortune as a physical guide, it can be surmised that cold fusion is actually a unique process of vacuum condensation which truly can take effect at absolute zero of temperature. On the contrary, the more plausible physics of the vacuum would suggest that all thermonuclear fusions are really vacuum evaporations that can only work at much higher temperature. Which of these contrasting physical ideas is correct remain to be seen. However, if it is hypothesized that the vacuum is simply the infinite sums of square of zero-point energies then the paradox of the changing signs of the temperature-pressure gradients can be made to disappear. This implies that the naked singularity has zero mass-energy density at infinite positive pressure. Both mass and energy acquire mass by the simple process of vacuum condensation at the expense of increasing absolute values of negative pressure equivalent to the cosmological constant of GR.
