Okay, so these might not all be things you’ll put on your Christmas list, but some of these are pretty cool.

 Self-inflating tires

Price: $200 each

As soon as the pressure in these Goodyear tires gets too low, they know it. An internal pressure regulator opens to allow air to flow into a pumping tube, and as the wheel turns, the flattened part helps squeeze air from the tube through an inlet valve into the tire. Once the air pressure hits an optimal level, the regulator closes — all without the driver’s realizing anything was wrong

 Bounce Imaging

Price: $500

An MIT student and an Army Ranger have come up with a way to provide first responders with the kind of technology elite SEAL teams have. To give firefighters and cops a full picture of a burning building or a hostage situation, the baseball-size orb is tossed into the area. Its six cameras snap pictures while its sensors detect air quality, temperature, radiation and other hazards. It then beams the data to mobile devices.

 Wingsuit Racing

Price: $600–$2,000 per wingsuit

In October, flying humans wearing batlike suits competed in the first ever Wingsuit Flying World Championship in China. Participants descended from 5,000-ft. cliffs, glided through a valley course and eventually parachuted down, covering about 3/4 of a mile in about 30 seconds.

 Google Glass

Price: $1,500

Glass is, simply put, a computer built into the frame of a pair of glasses, and it’s the device that will make augmented reality part of our daily lives. With the half-inch display, which comes into focus when you look up and to the right, users will be able to take and share photos, video-chat, check appointments and access maps and the Web. Should be available by 2014.

 The MakerBot Replicator 2

Price: $2,199

Download or create a design, hit Print, and watch as this sleek, desktop-size 3-D printer extrudes ultra-thin plastic layers, each melting into the one below to create an object—or, if you want, hundreds of copies of it. So basically, anyone’s home can become a mini factory.  Here's a link to the video explaining what it is and how it works.  Wicked cool  http://youtu.be/AKTSdW7-H3Q

 Bahar Towers

Price: $245 million

In Abu Dhabi, where temperatures peak at well over 100°F, keeping buildings cool is a challenge. Al Bahar Towers feature a facade with intricately designed shades that open and close in response to the sun, reducing heat gain by more than 50%.
