New technology can help vessels glide quickly over water in less time and with fewer emissions than their diesel counterparts ...

A material that emits less energy than it absorbs has the potential to save some of the sunlight wasted by solar collectors.

It is possible to make a material emit more radiation than it absorbs, violating the laws of physics in a way that could make ...

Town officials call say a power surge an "Act of God." But lost home appliances and municipal financial documents suggest ...

A new material developed at Penn State defies a fundamental law of physics, opening doors to highly efficient solar cells.

Why do some changes in nature unfold gradually, while others occur in the blink of an eye? Rust forming on metal is a slow, ...

You may think you know static electricity, but its true nature has long eluded scientists. We’ve now made a huge leap towards ...

This paper deals with the design, the setup, and the operation of a rotating contactless energy transfer (CET) system. The system is used to replace the slip rings of an electrical excited synchronous ...

A simple equivalent-circuit model is developed for a wireless energy-transfer system via coupled magnetic resonances, and a practical design method is also provided. Node equations for the resonance ...

Photocatalysis is increasingly used as an effective tool for green synthesis, where the precise activation of specific chemical bonds is crucial for achieving high selectivity. Descriptor-based ...

An electric bill can be a confusing thing to read. You’re not only paying for the energy that powers your TV, fridge or air conditioner.
