Burning 165 gallons per mile across Florida flatland, the crawler transporter has hauled three entirely different rocket programs across six decades and no replacement has ever been ordered
5+ hour, 58+ min ago (708+ words) The gravel under it gets ground to powder. Not all at once. Surveyed and replenished, because each steel tread shoe weighs about a ton, and there are 456 of them. The machine covers four and a half miles of Florida flatland…...
A trailer sized solar desalination unit ran for 6 months on brackish desert wells in New Mexico, making up to 1,320 gallons of drinking water a day with almost no battery storage
7+ hour, 58+ min ago (612+ words) The trailer sat at a federal research site in Alamogordo, New Mexico, hooked to wells nobody would ever drink from. The groundwater below was brackish and bitter, too salty to swallow and too plentiful to ignore. Solar panels beside it…...
Carpet recycling hit 38 percent in one state while the rest of the country stays near nine percent, and a fee charged on every square yard sold is what paid for the difference
9+ hour, 58+ min ago (655+ words) The installers roll the old carpet up and carry it out in strips. It weighs more than most people expect. Beneath the surface, three or four materials are fused so tightly together that almost no standard facility can pull them…...
Steel arch spans weighing 5 million pounds each rode the Hudson River for 30 hours apiece, and crews then jacked all three of them 60 feet straight up over the Hackensack
16+ hour, 58+ min ago (867+ words) Three tugboats sat in the dark water at the Port of Coeymans, lines taut, waiting for the tide. Behind them on a heavy barge rode something that weighed five million pounds and stretched 400 feet from end to end. It was…...
Dried sea lettuce ground into powder and blended into cement at 5 percent of the mix by weight held construction grade strength while cutting the cement's global warming footprint by 21 percent
17+ hour, 58+ min ago (686+ words) The bowl of green powder on a lab bench in Seattle looked like something from a kitchen, not a construction site. It was sea lettuce, the same limp weed that drifts through cold Pacific Northwest shallows. A research team dried…...
A 12 month project in Laramie cooked the resin out of scrap turbine blade in vegetable oil and got back an oil that softens tired road asphalt, but the commercial agent it was measured against is vegetable oil too
1+ day, 7+ hour ago (784+ words) Old asphalt is not dry. That is the first thing to get wrong about it. A road binder starts out as a suspension, with hard sticky particles carried in a lighter oily fraction that keeps them apart. Sunlight and air…...
Each of the 89 concrete boxes being cast beside a Danish harbor is 712 feet long and gets towed to sea by tugboats, while the box itself very nearly floats and is sunk on purpose with water pumped into it
3+ day, 9+ hour ago (786+ words) Weight is not what makes an object hard to move across water. Displacement is. A ship of 80,000 tons is moved by tugs every day of the week, and nobody finds it remarkable. So the interesting question about a tunnel section…...
Two gantry cranes going up over a dry dock in Dalian span 840 feet between their legs and hoist a load 328 feet into the air, which is a span no shipyard crane anywhere has matched
3+ day, 10+ hour ago (805+ words) A shipyard crane is not really limited by what it can lift. It is limited by how far apart its two feet can stand while it is still lifting that load. Widen the span and the girder between the legs…...
A 5,000 ton Art Deco terminal in New Jersey was cut into three pieces and rolled three quarters of a mile across a working airfield, and the dollies had to hold every lift point in step from the first foot to the last
3+ day, 19+ hour ago (647+ words) The runway lights were still burning when the order came to move. Beneath a flat New Jersey sky, about 200 rubber tire dollies sat packed under steel beams, each linked to a central hydraulic system. Above them, 5,000 tons of concrete, brick…...
Wind turbine blades usually end their lives buried in landfills, but a German manufacturer says its 63-foot wooden blades milled from laminated veneer lumber resist fatigue better and cost about 20 percent less to make
3+ day, 23+ hour ago (801+ words) A workshop floor, a gantry rail overhead, and a long pale shape lying under it that looks like furniture. It is spruce, glued up in layers, and a cutter is walking down its length taking off curls of shaving. What…...
