    "abstract": "Considering the stresses due to the vacuum fluctuation and the electric\ncharge loaded over the surface of a spherical cavity, we estimate the maximum\nvalue of the charge. Since this value is independent of the cavity size and\nparameter free, it is regarded as the electric unit charge. Our result is $Q=\n1.55\\times 10^{-19}$ Coulomb which implies the relevant fine structure constant\n$\\alpha=1/145.90$.",
