Thats right make your own fresh water and never water your plants again. Here is how I made a small working prototype that waters a single plant and I never have to worry about watering that plant again.

I removed an old peltier thermal chip from an incar beer cooler and made a water creating device. I takes the moisture from the air and condenses it just like a cold beer on a hot day. the water then runs down into the planter box and keeps the plant watered. never have to water the plants again, no worries about busted hoses again, and I can control the amount of water via a timer and PWM circuit so I don't over water the plant.

Could I collect the water into a container to collect for ER sutuations?

Yes you could

Do you have a step-by-step, by any chance? Maybe some build pictures? If not, is there any way you could throw together a diagram showing your build? I've been looking for pretty much this exact setup for a while now! I love the idea of a solid state air water generator!

I'll do better than that.I'll sell you the one I have.

While I appreciate the offer, buying a completed unit is much less satisfying than assembling one from scratch. I've got most of the parts, I believe.

Ill send you some info.

Fantastic idea! Could you please send me the info too.

This is great. Do you have any info on sizing (i.e. - what size heat sink, what size peltier, yeilds how much volume for a given humidity point)?

Cool idea.... get it? I love peltiers and this is a novel use i haven't seen yet

i wouldnt waste my money on a separate device.. how about just rigging your AC condenser drain pipe to your potted plant?

also my air conditioner is in the basement. and not all that easy to get the water to the plants. i just wanted to have something that I could use if I went out of town for a while or if I kept forgetting to do it. I have some Bonsai plants that have in the past been abused, and I thought this would ensure the would still be alive when i got back from a long trip.

thanks for your input I do appreciate it.

great but not modular hard to rig all those lines
