AI data centers are demanding a more efficient power grid, not unlike what Thomas Edison championed nearly 150 years ago.

A diode is a semiconductor device that allows electrical current to flow in one direction while blocking it in the other.

Every house with a PV system that draws electrical energy from the grid and can feed surplus energy back into the grid must be able to reliably distinguish between these two operating states. How does ...

From land, a rip current can appear relatively calm, as a strip of water that extends out between breaking waves. Its appearance can be deceiving. By Christine Hauser and Hannah Ziegler Hurricane Erin ...

The harnessing of electricity has played a pivotal role in human history and has exponentially expedited our growth as a species. Since becoming a household commodity in the late 19th century, ...

A 2025 research paper showed that a major ocean current in the Southern Hemisphere reversed directions for the first time in recorded history. Rating: False (About this rating?) Context: The paper ...

Startups developing voice AI technology and applications are having their moment. Model builders like ElevenLabs and Cartesia have raised millions of dollars in the last few months. Applications such ...

Researchers at the Monash University Department of Materials and Science and Engineering have developed a water-based battery potentially capable of providing compact, high-performance battery systems ...

The battery as we know it today was an invention of Italian chemist and physicist Alessandro Volta. He witnessed electricity splitting water into its constituent elements of oxygen and hydrogen and ...

We’re familiar with single-phase AC at the outlet, but multiphase AC offers advantages and is necessary for higher-power installations. For most engineering designs, the circuit’s DC operating power ...

This basic non-contact transducer is often used to measure AC currents. Accurate measurement of static and dynamic current flow in a conductor is a common requirement in many circuits and systems.
