Peltiers are a fascinating piece of tech, I remembering hacking together a cooling system for a high school project (20 years ago now..) to show people and have had a fascination ever since. Problem is they just aren't that useful due to their large inefficiencies. Situations where power consumption, heat removal and humidity aren't a problem are pretty rare at any scale. Saying that, if a situation where heat removal is straight forward due to other factors, space is abundant with solar generation (that's not needed/can't be used for anything else) and humidity is benefit, peltiers size and simplicity can be leveraged nicely.
