Habitable Venus

[iancampbell]

IIRC, the current thought is that a major cause of the Venus hothouse is that it rotates extremely slowly. This leads to just about no magnetic field, and in turn that leads to the lighter components of the atmosphere being stripped away by the solar wind. This apparently happened because solar UV split water in the upper atmosphere and the hydrogen was blown away. Which in turn leads to very low water levels. Early life lived in the sea, a bit difficult if there isn't much sea.

So would a Venus rotating at something close to the rate Earth does remain habitable to date? Has any simulation work been done?

Incidentally, no water leads to no plate tectonics.
