This is the $250 Bedjet Bed Heater & Fan (currently a Kickstarter project). It blows hot air under your covers to keep you warm at night so a lover's cold foot doesn't lead to a breakup. I know that at least a fan-only version of this has existed for awhile because I remember seeing it in a Skymall catalog on a flight once while the guy next to me was coughing on my neck. But this one doesn't just cool your bed, IT CAN HEAT IT TOO. Holy shit! Allegedly by up to 30-degrees in less than three minutes. For reference, that's hot enough to cook your penis to medium-rare before you even fall asleep.
Keep going for the Kickstarter video. Alternatively, tape a dryer hose to a space heater and jam it up the ass-flap of your pajamas.
Thanks to me, for managing to get out of bed every morning even though I know the world outside will never be half as good.
