I press it to my face to answer that question. Somehow my face is much more reliable at telling the difference between cold and wet than my hands.

I just mentioned the "wet or cold" problem to someone else and they said "just use your face"! So it's not just you. Something to try this winter...

Doesn't using your tongue, which is usually wet, increase the chance of a false positive?

Alternatively, a clothes rack on a balcony or receiving direct sunlight through a window or glass sliding door, with both slightly ajar works well. One benefit of this is that your clothes last much longer.

In the winter, I find they dry quite quickly if I just put the clothes rack indoors near a radiator.

However never hang clothes on a radiator to dry, this is the least efficient method of using your radiators.

Can you put your clothes on a fire escape? Or in your bathroom (works great if you have a bathroom with a window).

Every apartment complex I've lived in has had rules banning hanging clothes (no idea about enforcement). Also, for any group larger than 2 I imagine the clothes would not dry fast enough to keep up. And most bathrooms are small and often without a window. Not a complaint, just pointing out that sun-drying is often not a real choice. Often it is.

Living in Beijing, we never dried our clothes outside the apartment. We had racks in the kitchen for that. I don't think management companies can ban drying inside! It sounds unenforceable.

If you have city central radiated heating, then making the radiators less effective is just a bonus of getting your clothes to dry a bit faster.

> At the end of the project, appliance manufacturers including GEA will be ready to invest in this technology and commercialize it. This will result in the U.S. becoming the leader in the clothes drying industry and generate new jobs and innovative applications of the technology. Pretty sure as soon as China is aware of this idea (if not already), they will have something in production and out the door faster and at…

GE appliances is already a Chinese company so pretty sure they have some chance to be the first to actually commercialize it. So no need to worry about China copying it..

As if I could ever find a clothes dryer in china.

I don't understand why this is such a valued aspect of dryers. All clothes coming out of the dryer for me go right into my drawers / hanging. They don't get worn at the very earliest the next day. I rotate everything so I'm not just wearing the same socks and undies over and over again, so the vast majority of the time they don't even get worn then. Is the psychological effect of folding warm clothes rather than cold…

Hanging hot fabric can sometimes flattens out wrinkles almost as well as an iron.

Well, if you're using a hotbox dryer, it's not the hanging up while hot, but rather the fact that you just steamed and tumbled them. That gets wrinkles out of anything. Hanging up just keeps new wrinkles from forming.

A bit puzzled why GE needs government funding to do research -- they make a lot of money already. The idea sounds pretty neat but I wonder about longevity of the piezeoelectric transducers. A clothes dryer needs to last at least 7-10 years, minimum. A resistive heating element is about as simple as you can get, and it's cheap to replace if it does burn out.

> The idea sounds pretty neat but I wonder about longevity of the piezeoelectric transducers. If they'll wear out fast it's entirely feasible to design the dryer around user-replaceable piezos. It may end up like with inkjet printers -- where the dryer itself is just a boring spinning drum with a fan and a moisture collector and a powerful piezo driver, and you end up buying consumable cassettes with the actual trans…

You know what I want? A lemon law that states that major appliances need to run forever. Literally something that says, "This device must run without professional service for 25 years." Forget energy star stuff, 100Kwh saved a year is meaningless because we can always optimize powerplants. Stop building disposable 100LB metal boxes that have to get scrapped and thrown in a landfill. If the device fails earlier than that, the company has to replace it and pay a large fine for producing faulty equipment (larger than the profit from the device by an order of magnitude).

Then just allow people to rent the devices (which would obviously cost more) rather that have to buy them outright.

Electric ceiling fan in a small room dries a stand full of clothes in 4-5 hours in a 70%RH climate and costs a LOT less than drum dryers and is safer for the garments.

This is how I dry all of my cycling kits, gloves, socks, warmers, etc. I have a four hanging drying racks [1] that I hang on the four ceiling fans in my home gym. The lycra dries in only an hour or two since there is airflow on all sides of the items. It makes for very efficient drying and it wholly prevents heat degradation of the lycra.

It's considered reasonable to endanger lives to dry washing? (I don't live in the US).

Well obviously don't be stupid where you put the clothes, (I.e. don't block egress).

It's not the fastest clothes dryer, but I often use one that runs on fusion in outer space.

Hanging clothes in direct sunlight is overkill, and probably reduces their useful life due to the UV. All you need is sufficient moving air. I hang mine under the deck or just on racks indoors.

Not sure why everybody assumes fusion powered implies direct sunlight.

Drying clothes in the shade is also powered by the sun, because the air only has "unused" moisture capacity because it was heated at some point. To repeat the cycle forever it will need to cool down and then be heated again.
