Nothing says "asshole" quite like this parasitic bike "emergency pump" from Instructables user Aleksi. Need some air? The local public parking lot is your oyster.


Don't be fooled. Pedalling around on a bike that chills your beers probably won't result in much weight loss. In fact, you may actually pack on a few as you enjoy the beechwood aged fruits of your labour. The bike has a heat pump attached to the pedals so the more you pedal the cooler the beer set inside the copper coil will get. It is just the incentive the lazy couch potato needs to get up and start moving. Next up, tackling the fresh air of the great outdoors.


The laptop stands we've used are great for keeping your supple thighs away from your burning laptop, but are usually fairly heavy and hard on your legs. This Airboard, however, has an inflatable base to gently sit on your lap, while at the same time providing ample distance so your leg hairs don't char. It's only a design, but is neat enough that if someone made a laptop stand like this, we'd have a hard time passing it up in stores.


There's a lot of water floating around in the air everywhere, and inventor Max Whisson has figured out a way to extract it using Max Water, a wind-powered contraption he named after himself. Max Water uses the concept of condensation, where lower temperature allows less water to hang around in the air, and Whisson says that will amount to 10,000 liters per day dripping from this single rooftop device. Man, that's a lot of water.

Those interested in this device better be mighty thirsty, though, because they'll have to shell out $43,000 for one of these babies. But if you've ever been in a region where there's no water, spending $43K is a whole lot better than dying of thirst. If this idea really works as well as its inventor says it does, economies of scale will make that high price a temporary hurdle.
