In an Army Corps of Engineers press release, details on the astounding rate at which workers are draining water from New York's subway and transit tunnels: "To date, the USACE has used about 50 pumps of various sizes to remove 64 million gallons of water from the New York City mass transit system. Operations are ongoing at six sites, with pumps removing about 116,000 gallons per minute. The 696,000 gallons the pumps are draining each minute exceeds the amount of water in one Olympic-size swimming pool (660,000 gallons). There were roughly 600 million gallons in the tunnels when pumping operations began on Thursday, Nov. 1." (via Noah Shachtman).
In post-Sandy "dewatering" mission, Army engineers drain one Olympic-sized pool's worth of water per minute

You can pick up a space shuttle thermal tile right out of the furnace
Watch as a tour guide pulls space shuttle tile material out of a 2200-degree furnace and picks it up immediately. Note that for best results, pick it up by the cool corner or edge rather than the white-hot center. If you're interested in the material and engineering, here is a great PDF on their thermal… READ THE REST
Robots made from ice to explore other planets
Ice is an abundant material in the solar system and researchers are exploring whether it can be used to build and repair robots. University of Pennsylvanian engineers presented their early work on ice as a structural material for robots in a paper at the IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS). The idea… READ THE REST
