Eh, I wouldn’t. It’s dumb.
You can buy a water harvester, looks like a water cooler thing, but has components pre built inside.
Peltier has shit efficiency, that’s super low throughput, only if there is sun. Then you have purification issues as it’s loaded with dust and Bacteria. These are things figured out by the above water harvester. In a nutshell they are a compressor driven dehumidifier with purification and control circuits built in.
You could recreate the wheel tho if you have such parts laying around. I built a system once to feed an entire commercial greenhouse, easier because you don’t have to purify.
I'm gonna give it a shot even so. Which water harvester have you seen?
Don’t even remember… guy brought it on to the office, I remember he said it was advertised on Alex Jones decades back. Worked well.
You can’t safely drink the water of what you build though without filtration and sterilization, it’s called condensate drain , you can get nasty diseases, even legionaries disease. Worth researching.
ou can’t safely drink the water
Most of the fresh water around the world isn't safe to drink. Sterilizing the water is a must no matter the water source.
Good advice; treatment is part of my plans.
