 Part of the prototype of "The Clock of the Long Now" - a 10,000 year clock. If you appreciate mechanical wonders, then you MUST visit this website.  Shear-Thickening Fluid (non-Newtonian liquid) will revolutionize body armor. Bullets and even ice picks are stopped by it. Amazing! U. of Delaware & Aberdeen Proving Grounds research.  Andrew Carol's masterpiece version of Charles Babbage's difference engine - made of Legos!
 This microfluidics reactor microchip is built from silicon using tunnels, valves, pumps, and porous membranes - amazing!  PC system built entirely from Legos.
|  Lightning striking Balad Air Base in Iraq.  Here are the inner workings of a Metcal SP-200 soldering station - in case you have ever wondered. I bought the entire setup on eBay for $61 (over $250 new).  Piezo actuators change shape when electrically excited. A SQUIGGLE motor consists of several piezoelectric ceramic actuators attached to a threaded nut, with a mating threaded screw inside.  Piles of circuit boards from hazardous computer waste stretch into the distance near an e-waste scrap yard.
 Well, this photo of a toppled transmission tower in Basra, Iraq, is not really "cool" since it represents terrorists destroying the world's accomplishments, but it is interesting.
