Volcanic rock–based formula reduces cement emissions by two-thirds

Electrical & Electronics, Engineering /

Researchers have created a volcanic rock–based formula that reduces carbon emissions by 67%, potentially providing a low-cost alternative to increasingly scarce cement additives. Cement—a manufactured powder that binds concrete—is the most widely used construction material in the world, but also one of the most polluting, responsible for nearly 8% of global greenhouse gas emissions. About […]

A new kitchen stove cooks food using water rather than natural gas

Engineering, Kitchen /

Greenvize has unveiled a compact hydrogen-powered cooking stove for both homes and commercial kitchens that can generate its own fuel from water. The device incorporates a proton exchange membrane (PEM) electrolyzer into a standard stove, enabling users to produce hydrogen whenever needed. It works by splitting water into hydrogen and oxygen through electrolysis. The hydrogen

Researchers are testing transparent wood as a glass alternative

Architecture, Engineering /

Transparent wood as a glass alternative could transform modern architecture by replacing brittle materials with a more sustainable option. This organic material provides much greater structural strength, contributing to safer building facades and improved urban thermal performance. In plants, stiffness and darkness come from lignin, a dense organic polymer that forms a cellular network responsible

Black Metal’ Solar Device Produces 15× More Power

Electrical & Electronics, Engineering /

Researchers have created a solar thermoelectric generator that delivers 15 times the efficiency of the latest leading devices. Researchers aiming for greater energy independence have investigated solar thermoelectric generators (STEGs) as a way to generate electricity from the sun. Unlike conventional photovoltaic panels, STEGs can harness both direct sunlight and other forms of thermal energy.

Pneumatic Exoskeleton Enables Overhead and Forward Arm Support

Robotics, Tech /

Prolonged work in fixed postures often fatigues muscles and causes musculoskeletal disorders because muscles do not handle sustained contractions well, even at low intensity. Gravity exerts maximum torque on the shoulder and elbow when the upper and lower arms extend forward horizontally, as in repetitive tasks like drilling. Exoskeletons for Musculoskeletal Relief Despite increasing automation,
