Ever had a humid, moulded apartment? I did! And can tell you it isn't pleasant at all. But there is a solution to it: Get a vase, fill it with water, freeze it in fridge, take it out and put it somewhere in the room on a plate. It collects up to one glass of water from the air every day. Really
works! But far from enough unfortunately. Anyway, that is not the idea. Here is the idea:
This device is the size of a coffee mug. It has a solar cell on top. It also has a fan, a compact A/C unit, a water barrier membrane, and an insulated water reservoir, oh and rechargeable lithium batteries. The solar cell powers the fan and the A/C unit. The fan blows air into the mug from the inlet, while there is a membrane on the vent hole. The air goes in and out while the humidity is trapped inside. The A/C kicks in and cools a coil inside the mug. The water condenses and drops into the reservoir. In an hour or so there is considerable water in the mug.
Say you go hiking, or you go for a long drive, or god forsake it you are left in a desert without water! I am sure you have experienced the case when you had to appreciate even a drop of water. Well now, you can have this mug with you and get at least a sip of water no matter where. Not going anywhere but want to use it to dehumidify you room? Put it in a corner and let it work for you all day with clean renewable energy. Price? $55 or so.
Baked, though at a different price-point.

What's the exact opposite of baked?

Someone made money off of this very idea! It was a scam, but money is still money. [goldbb, May 15 2017]

Got a humid, moldy apartment? Here, have some tepid, moldy water. |
|

I sorta like the idea of a self-filling coffee (or water) mug |
|

There are quite a few water-from-air extraction systems around. They generally use about 500 Watt-hour per litre, i.e 125 Watt-hour per mug (250ml). That's a lot of energy for a glass of water. You're either going to need big solar panels or a lot of patience. |

//moulded apartment//
Injection or vacuum? |

Don't bother with AAs, just put a big lithium pack in it. |

But keep the lithium well away from the water... |

Or you could add the feature onto the functionality of the air conditioner. Now your air conditioner is also a dandy water cooler, no batteries required. |
|
| |
Although, if you have a tap, the water that comes out of it is probably disgusting. |
|
| |
Have you looked at the water that comes out of an air
conditioner?!? |
|
| |
No, but I it is easier to filter air than water (because air is less dense), in this case filtering the air filters the water by proxy. Many aircons already have this ability. |

Shirley the key here is to wait for the most advantageous
conditions? Take a solar system, + storage, monitor the
temp + humidity until it comes as close to the dew point
as
possible then dump all your energy into your cooling
system
then. |
|
| |
The downside of course, is that all your lovely water that
you've just extracted from the air might get washed away
by the
rain that, purely by coincidence, is falling. |
