I've always thought how nice it would be to have a cool, consistent breeze blowing up my shorts. I'm actually in the process of developing my own take on Air Jordans, called Air Up There Jordans. They'll have a ring-shaped fan built into the cuff of each high-top for perpetual below-the-belt and above-the-knee refreshment. You'll be able to help crowdfund them on Kickstarter in the coming months. And in the interim, you can check out this bed fan. It does what my shoes will, but on the horizontal plane.
Maybe you're hot when you lie down for the night. Or maybe you go to sleep bundled up and cozy, only to wake up a few hours later sweating and kicking the sheets off. The Bed Fan tucks between your mattress' top and bottom sheets to circulate and concentrate cool air under the covers, keeping your body temperature in check and eliminating nights of waking up at 2 a.m. and realizing you've sweat the bed.
Bed Fans include a wireless remote that can sit on an adjacent nightstand to turn the unit on/off, plus adjust cooling intensity levels with a single twist knob that does not require turning on the lights, or having much of an education, to operate.
