A 464-ton German machine named Caroline is grinding through chalk 135 feet under the Thames, and scattered through that chalk are flint nodules harder than the concrete rings she bolts up behind herself, some of them at 145,000 psi
17+ hour, 38+ min ago (852+ words) Anyone who has ever pushed a long drill bit through a fence post knows the problem. The deeper the hole gets, the more the bit wants to wander off line. Under the Thames, where a 464-metric-ton machine named Caroline is…...
Norway stood 6,400 solar panels dead upright on the roof of an Arctic cold store, loose on the membrane with nothing holding them but friction, because a flat panel under a few centimetres of snow produces nothing at all
19+ hour, 7+ min ago (1028+ words) Which makes the roof of one very interesting. It is usually flat, usually enormous, and usually doing nothing. The largest cold store in Tromsø, a Norwegian port city sitting at 69 degrees north, well inside the Arctic Circle, now has 6,400 solar…...
Supercars are in trouble: Influencers may flock to them at Monterey Car Week, but rich people aren't actually buying them
1+ day, 5+ hour ago (1155+ words) I think there is no denying that a McLaren looks fresh as heck with its doors up, that a Lamborghini looks straight out of a Grand Theft Auto Online server. Supercars look cool, and they usually have performance to match....
Jay Leno's classic car law cleared the committee that killed the last version, and it would let 1976 to 1985 cars skip California's smog check for good, which is a window that leaves out almost everything in Leno's own garage
1+ day, 7+ hour ago (932+ words) Can you imagine owning 181 vehicles? If that already seems like a ton of maintenance and upkeep to you, now imagine having to get most of those vehicles to pass a smog test every few years. That’s the reality that Jay…...
Japan switched one reactor back on at the biggest nuclear station ever built after fourteen years dark, and three weeks later the utility that owns it started switching off solar farms for the first time, up to 3,290 megawatts on a single afternoon
1+ day, 8+ hour ago (1491+ words) The Fukushima meltdowns get remembered as something that happened to one plant. What they actually did was switch off an entire country. All 54 of Japan’s reactors went dark, and a nation that had been pulling roughly 30 percent of its electricity…...
A 10-ton Ukrainian drone submarine that is wider than it is tall sat on a stand in Paris built partly to hunt other underwater drones, and six weeks later the US Coast Guard asked American industry for anything that could kill one
1+ day, 10+ hour ago (1375+ words) There is a hard engineering reason for that, and it has nothing to do with styling. Which is what makes the machine a Ukrainian company parked on a stand at Eurosatory in Paris back in June worth a second look....
Three steel squares 45 meters a side left a French port under tow with a 10-megawatt turbine already bolted on each one, rode out a Gulf of Lion winter with nothing damping them but the seawater trapped in their own bellies, and have run flat out since May
1+ day, 11+ hour ago (947+ words) Keeping water out of the structure is most of the job in marine engineering. Ships, oil platforms, offshore wind foundations, the entire business runs on the assumption that the sea stays on the outside. France’s newest floating wind farm runs…...
A Swiss tomato grower hung 1,736 solar modules inside his greenhouse directly over the rows, and they take only the infrared the plants never use, so the crop came out 1 percent up and the pickers started working under them because it was cooler
1+ day, 13+ hour ago (582+ words) Put a solar panel anywhere near a crop and you have started a fight. The panel wants sunlight, the plant wants sunlight, and there is only so much of it falling on any given acre. Nearly every agrivoltaic project ever…...
A 4,350-ton boring machine that bends at the waist launched 147 feet under a suburban cricket ground in Sydney this week, and it changes its own worn cutting teeth without sending anyone into the head
1+ day, 14+ hour ago (769+ words) Tunnel boring machines are built around one idea that has held for decades: make the machine a rigid steel cylinder, aim it carefully, and push. Stiffness is what keeps a cutting face honest when it is chewing rock at full…...
A 7,800-ton floating turbine standing more than 1,000 feet tall started feeding a Chinese oilfield this month down a 2.7-mile cable, and the company running it is the same one that walked away from buying Scottish floating wind for its North Sea rig
1+ day, 16+ hour ago (1313+ words) The industry’s answer was to stop burning and start plugging in. Scotland took that further than anyone, consenting a 560-megawatt floating wind farm called Green Volt about 50 miles off Aberdeenshire, with a job description that includes running North Sea oil…...
