Dr. Brandon Ennis, Sandia National Laboratories’ offshore wind technical lead, had a radically new idea for offshore wind turbines: instead of a tall unwieldy tower, with blades at the top, he imagined a towerless turbine with blades pulled taut like a bow.
Researchers at Columbia University, supported in part by a grant from the U.S. National Science Foundation, conducted a study that modeled the seasonal variability of solar and...

This compendium of recent articles from the editors of Tech Briefs and Aerospace & Defense Technology looks at the latest advances in power electronics and energy storage for a range of applications...
In place of the usual gasoline-powered motors, the X-57 has two all-electric motors powered by traction batteries.
Additional applications include defogging/defrosting, wearable devices, industrial heat systems, sensors, thermochromic displays, and microfluidic chips.
A highly sensitive system for detecting the production of hydrogen gas can foster the development of hydrogen as an alternative to fossil fuels.
Hydrogen has emerged as an important carrier to store energy generated by renewable resources, as a substitute for fossil fuels used for transportation, in the production of ammonia, and for other industrial applications.
