The First 3D-Printed Two-Story Home in the US New York design firm Hannah, Germany-based company Peri 3D Construction, and Texas engineering and construction firm Cive have partnered to create the first 3D-printed two-story home in the US—currently being built in Houston. The 4,000-square-foot, three-bedroom property will serve as a case study on how to best streamline 3D-printed construction, test the capabilities of the machine and …
Souterrains are subterranean passageways in the Scottish Highlands from the Iron Age. Nobody, however, has seen one fully intact or understands what function they served. While surveying them has been a lengthy and difficult process, archeologists are now using laser scanners (the Leica BLK360, in particular) to make them more accessible. This new equipment can scan the walls of souterrains at 10,000 times a second, …
For the first time ever, scientists have redirected the path of lightning bolts with lasers. During a demonstration atop Switzerland’s Säntis mountain, researchers fired rapid laser pulses at thunderclouds for more than six hours and observed lasers diverting four different lightning strikes. One was filmed in clear enough conditions to demonstrate how the bolt steered the path of the laser for around 50 meters. A laser …
