Static electricity could help run air conditioners

An invention made from waste polystyrene that generates static electricity from motion and wind could lower power usage by recycling waste energy in air conditioners and other applications. More than 25 million tonnes of single-use, polystyrene packaging materials are made globally each year, but only a tiny fraction is recycled—most of it goes to landfill […]

Digital Wallet vs. Debit Card: Which Is Safer?

Digital wallet usage is skyrocketing, according to a recent J.D. Power study. It showed that almost half of Americans had used a digital wallet in the previous 90 days. They’re such a convenient way to store debit and credit cards, loyalty cards, gift cards, and more, that I often leave my actual wallet at home. […]

Hyperspectral image sensors help characterize polymers in electronic waste to improve recycling

Plastics make up around a quarter of the materials contained in electronic waste (e-waste). The proportion that is recycled is comparatively low—the majority is simply incinerated. The first step to improve recycling is the identification of polymer materials, so that they can be selectively sorted and processed in a way that preserves their function. Researchers […]

3D smart energy device integrates radiative cooling and solar absorption

A research team led by Professor Bonghoon Kim from DGIST’s Department of Robotics and Mechatronics Engineering has developed a “3D smart energy device” that features both reversible heating and cooling capabilities. Their device was recognized for its excellence and practicality through its selection as the cover article of the international journal Advanced Materials. The team collaborated with Professor […]

Southeast Asia Will Be a Major Energy Power for the Next Decade

Southeast Asia’s role in the global energy system is set to grow strongly over the next decade, according to the International Energy Agency’s (IEA) most recent publication. The region will contribute heavily both to energy production as well as global demand, as its population expands rapidly, and several countries undergo industrialization. Several emerging economies, such […]

Could seaweed farms become the next generation of mines?

Blue Evolution, a California-based regenerative ocean farming company, announced Thursday it has merged with Blu3, a company specializing in regenerative ocean technologies. The move, Blue Evolution said, creates a combined entity that will leverage enhanced R&D capabilities to drive innovation and commercialize new seaweed-based products across multiple sectors – agriculture, biomaterials – and critical minerals.
