Elon said the Boring Co. is also going to do tunneling for water transport, sewage, electrical. The Boring Co.’s first test project opens next month in Hawthorne, a Los Angeles suburb. In a few years, Boring Company tunnels could take …

batteriesNanotube film enabling ten times higher energy lithium metal batteries

12 Comments
Thin nanotube films effectively stop dendrites that grow naturally from unprotected lithium metal anodes in batteries. Over time, these tentacle-like dendrites can pierce the battery’s electrolyte core and reach the cathode, causing the battery to fail. That problem has mostly …

buildings3D printed knitted frameworks enable breakthrough complex architecture

14 Comments
3D printing of knitted textiles has been used as a structure for complex architecture. This cuts down on material, labor and waste, and simplifies the construction process for complex shapes. A double-curved concrete shelled pavilion was made with 3D-knitted formwork. …

materialsA Wheeled Robot Driven by a Liquid‐Metal Droplet

5 Comments
A palm-sized robot has been made with a drop of liquid metal in a plastic wheel. The robot’s wheel rolls when the liquid metal changes the center of gravity, which is controlled by altering the voltage through the embedded battery. …
