A large alloy heat-sink fan (passive, with fins, not a motor driven one), with the base custom-moulded to suit the shape of the wearer's back.
Straps firmly around the waist and shoulders to ensure a good night's sleep (face-down, of course) on even the hottest nights.-- m_Al_com, Jan 24 2007 fins? Oh, those type of fins.-- skinflaps, Jan 24 2007 You know, those black alloy heat-sink fins that you attach to high-power transistors and stuff.
I'll render something up, if there's any demand.-- m_Al_com, Jan 24 2007 This is only good if you don't roll over at all while you sleep. So, not good for me at all. Also, probably a safety hazard for anybody with long hair.-- 21 Quest, Jan 24 2007 //safety hazard for anyone with long hair//

<scurries off to render>-- m_Al_com, Jan 24 2007 Why not just put a high-powered cieling fan over your bed?-- 21 Quest, Jan 24 2007 The noise keeps the girlie awake.-- m_Al_com, Jan 25 2007 halfbakery
