Actually,isn't light pressure from the star going to be a restoring force?

comment Energy formula for separating $O_2$ from mixture of $O_2$, $NH_3$ and $H_2O$
I assume theoretic lower bounds on the energy would apply even to semipermiable membranes. Is that correct?

comment Energy formula for separating $O_2$ from mixture of $O_2$, $NH_3$ and $H_2O$
I'm currently (grossly) approximating this as: Specific energy cost to liquefy NH3 at ambient (J/kg) * Oxygen Effluent Impurity Rate Per Area (kg/s/photobioreactor) * ( 1 + 1/Growth Medium Gas Tolerable O2 Fraction )

comment Effect of rotation on turbulence threshold for Reynolds number?
Waterspouts as in tornadoes over water. Lots of videos of them on youtube and its hard to imagine turbulent flows dominate them.
