I've thought about buying an old 200mm or 230mm fan, and hooking it up to a Peltier cooler -- First pass the air over the "cold" side to drop out the moisture, then through some rechargeable desiccant, and then through the hot side to my clothes.

I wonder why dryers don't work this way, other than I think that it'd be much slower to dry as compared to a traditional dryer, and I'm not sure if you'd be able to wick the moisture out of ever fabric.

Why rechargeable dessicant when moisture just condenses on cold side? Then it drops into container. Also peltier cooler is too inefficient to do this. It uses about half of energy just for resistive heating. Typical european dryer works just like this but doesn't use dessicant.

Unless you drop the air temperature down to below 0, all the moisture won't drop out on the cold side.
