Clean tech, engineering breakthroughs and space exploration
The Technology section covers clean tech, engineering breakthroughs, space exploration, desalination, advanced materials and green innovation. Inventions and cutting-edge projects that could help solve environmental challenges and change everyday life.
Chile is turning 2,175 miles of undersea internet cable into an earthquake sensor, and a study found it can size a quake five seconds after the first waves
Engineers in Austria stacked 3D-printed clay cubes into a ceramic cooling wall that soaks up water, and in a hot attic one cube cooled the air beside it by almost 12.6°F
A tugboat and a crane barge helped move the 45,000-ton Battleship Wisconsin about five feet off its Norfolk pier, its first move since 2000, so crews could replace the fender cushioning its hull
In Yunnan’s Yanjin, the so-called world’s narrowest city squeezes homes into a river valley that narrows to about 98 feet, and the famous 400,000 population figure actually covers the whole county, not the town
In Japan, researchers led by Tohoku University used an inexpensive blue pigment to turn carbon dioxide into methane with 79.5% Faradaic efficiency, and methane selectivity stayed above 60% for about 80 hours
A company won a mining license for a magnesium deposit it estimates at more than 50 million metric tons near Rășinari, in Romania’s Sibiu County, and the EU gets 97 percent of its magnesium from China
At Japan’s car parts shipping sites, workers read about 10 barcodes per product until DENSO’s Masahiro Hara created the QR code in 1994, and it now tracks glass eels for an expected 10,000 traders a year
Pegasus, a 16-foot-wide drone built by three Australian companies, flew for almost 2 hours over Queensland on a single lithium-sulfur battery pack, and its makers now expect missions of 5 to 8 hours
Louisiana’s Lake Peigneur emptied into a salt mine within hours in 1980 while a Texaco rig drilled on the lake, and about 50 miners escaped, but federal investigators never pinned down the exact cause
Physicists fired a laser at the plastic used in drink bottles and recovered nanodiamonds just 3 nanometers wide, after each shot hurled about 10 trillion of them at more than 22,000 mph into a soft gel
Robots built by the Israeli company Ecoppia roll along desert solar panels every night and brush off the dust without a drop of water, saving about 2.6 billion gallons so far, according to the company
Norway’s King Harald V now lies in a boat-shaped sarcophagus carved from olivine, a green Norwegian rock that can bind CO2, but no one has measured how much carbon the royal tomb will actually take up
A retired hobbyist built a vacuum tube computer from 460 recycled 1950s tubes, and the 8-bit machine needs about 10 minutes to stabilize and, in his words, heats the entire room
University of Queensland engineers made a coating that releases rust-fighting molecules where it is damaged, and lab tests showed corrosion over 600 times slower than some top paints
Anduril’s three-ton Dive-LD underwater robot lets seawater flood through its outer body to survive depths of 6,000 meters, can operate for up to 10 days and is now being developed for tasks ranging from military missions to inspecting offshore wind cables on the seafloor
SpaceX recovered Ship 40 after its 171-foot Starship upper stage survived reentry, splashed down in the Indian Ocean and spent about 24 days at sea, giving engineers the first largely intact spacecraft of its kind to inspect for clues hidden in its battered heat shield
A 132-pound underwater robot surveyed North Sea drilling sites without a dedicated survey ship, and its developer says the system cut costs by up to 92% while producing detailed seabed maps in water more than 100 meters deep
