Made of a conductive metal, it has all the comforting weight of a winter blanket with none of the warmth.

I'd like one, please. [+]

I made some chain mail out of SS washers and it is amazing stuff. It feels liquid like, so I could see the appeal of a cool blanket on a hot day. (+)

I have always been worried about arrow attacks while I sleep.

My one experience with wearing chain mail was like carrying furniture underwater. I don' think I'd sleep very well.
-- normzone, May 16 2008


Yeah, unless it was aluminum I don't think I'd be very comfortable. More power to you, though.

Really great idea! I want one, now! [+]

Actually, as a lower sheet this may do well too. Since ambient temperature is usually somewhat below body temperature, and this device acts in an opposite fashion to a blanket (heat conducting vs insulator), it would work very well as a cooler. As a lower sheet, it would be stretched for maximum surface area and good heat dissipation.

Perhaps I could attach a peltier cooler to it, for some extra heat removal? Also, thin wires woven along the length to aid in conduction, just in case the links are slow to transfer heat due to minimal contact area at the joints.

Other advantages: no static cling, no cleaning required (just throw it in the oven at a few hundred degrees to burn off organic matter), can be used as a heater if current passed through, will prevent bed-time tasering, provides EM shielding, if made of nitinol - a quick current passed through to heat it will cause bed to make itself, no wrinkles and stores easily in a bucket, can be quickly rolled up then folded and used as a weapon, lasts a long long time, very easily recycled.

[+] but it would also remove all your body-hair, from getting caught in the links. You may or may not find this a desirable feature.

Just a couple of notes: Aluminum is bad because the oxide layer is BLACK and will turn you the same. Rub your finger on some Aluminum foil sometime. Don't use galvanized as the smell is horrible. I did my first test using galvanized washers and it litterally stunk.

The other thing I was thinking is that when you are a kid, you think monsters can't get thru blankets and in this case it might be true.

I am with [FlyingToaster] on this one. Epilady are probably pulling their hair out in commercial angst.

When I was a wee lad, I had to sleep under a "comforter" that was made of many, many layers of non-fluffy material. It was so heavy that I couldn't even pick it up. It was crushing and cold. Thanks for the flashback.

Actually, chainmail would be more conforming and a lot classier. [+]
-- baconbrain, May 17 2008


Great. I like to sleep *under* something - which isn't always good in a heatwave.
-- wagster, May 17 2008


I have thought of this too but didn't post... I want one!
-- sninctown, May 17 2008


Wouldn't you be a bit more likely to get struck by a lightning bolt? While you were napping????
-- blissmiss, May 18 2008


//Only once.//

Classy.

I would like a chain-mail blanket. I would like a chain-mail anything.
-- MikeD, May 18 2008


[+] I hope it comes in bronze or stainless steel... I'd prefer something rust/corrosion resistant.

Ian, even though sleeping under a chainmail blanket might make you more likely to get hit by lightening, it could also double as a Faraday cage, if were properly grounded.

A security blanket.

Brass would be nice. Cheap, pretty. The cooling application of this is appealing to me.
-- bungston, Apr 14 2010


Use anodized aluminum wire, no oxide formation, and feels slicker than bare aluminum. Loses a little bit of heat conduction, but only a bit.

I would advocate the usage of mithril in blankets. If you get attacked by an ogre in your sleep, then you'll be ready.
-- DrWorm, Apr 14 2010


and how is mithril supposed to defend against ogres ?
-- FlyingToaster, Apr 14 2010


(+) for making it possible to shout, "I have found the missing link!", and mean it.
-- 2 fries shy of a happy meal, Apr 14 2010


[FlyingToaster], testing has showed that mithril is 100% ogre- spear resistant.
-- DrWorm, Apr 14 2010


//100% ogre- spear resistant// But what's its thermal conductivity?

Orc-proof bedware. Nice. [+]

[DrWorm] but ogres use clubs.
-- FlyingToaster, Apr 14 2010


//but ogres use clubs//
In which case you'll need the Electr-o-stiff (tm) instant rigidity electromagnet option.
-- coprocephalous, Apr 14 2010


yes, but that only works with female ogres... well mostly.
