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

Leave a Comment / 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

Leave a Comment / 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

Leave a Comment / 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

Leave a Comment / 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.

Engineers developed a light-activated gel that boosts ion conductivity 40o TIMES

Leave a Comment / Electrical & Electronics, Engineering /

Unlike rigid electronics, living systems are soft and flexible. MIT engineers developed a biocompatible, flexible gel whose light-controlled conductivity could advance human-machine interfaces and soft robotics. Welcome to the emerging field of ionotronics, which transmits information using ions—charged molecules—much like electronics relies on electrons. While electronic systems are established, ionotronics is still emerging—except in living

15-Year-Old Filipino Creates Phone-Charging Shoes

Electrical & Electronics, Engineering /

At just 15, Filipino student Angelo Casimiro transformed a simple activity—walking—into a way to charge devices with his self-designed, energy-generating shoes. Equipped with piezoelectric materials in the soles, the shoes capture the kinetic energy from each step and convert it into electricity, enough to power small gadgets like phones or flashlights. Turning Walking into Practical

Novel Electrolyzer Converts Plastic-Waste Syngas Into Ethylene Using Lower Energy

Engineering, Material Technology /

Producing one ton of ethylene generates an equal amount of carbon dioxide. With global ethylene production exceeding 300 million tons annually, the industry has a significant carbon footprint that researchers aim to reduce or eliminate. A new device from Ted Sargent’s lab at Northwestern University offers a step toward achieving that goal. The device, an
