[Space]: Habitability modifiers for tidelocked and resonant worlds

[SuedodeuS]

I (somewhat) recently saw a show about "green" technologies, and one of the devices shown was an A/C unit that worked during nonpeak hours by freezing a reservoir of water at night. During the day, it circulated a coolant fluid that would essentially absorb the heat in the building and dump it into the ice (slowly melting it as the day went by).

If we're talking about a civilization advanced enough to colonize alien worlds, they may have the means (although it would certainly take some time) to use a similar scheme on a tidal-locked or even resonant worlds. Creating a massive A/C system might work to more efficiently transport heat, thus warming up the dark regions and cooling down the bright ones. This would certainly improve the habitability of such planets up to around the level of those with more Earth-like days.

Failing such massive terraforming (terraforming would be the proper term for the A/C "irrigation" thing, right?) projects, of course, I heartily agree with Brett's recommendation for a Habitability modifier for such planets.
