The quantum effect that could power next-gen, battery-free devices

A wafer-thin flake of bismuth telluride can act a little like a one-way street for electricity, even when the push comes from an alternating signal. But the direction of that “street” is not fixed. Moreover, if you warm the material up, the signal can flip. That temperature-triggered reversal sits at the center of a new study of the nonlinear Hall effect. This is an unusual quantum response that can turn alternating current into direct current w…

Gyroscopic wave device targets broadband ocean power

Osaka, Japan (SPX) Feb 18, 2026 Ocean waves offer a vast and predictable source of renewable energy, but many existing technologies only perform efficiently under limited sea conditions. In response, a researcher at The University of Osaka has carried out a detailed analysis of a gyroscopic wave energy converter, or GWEC, to explore its potential for practical large scale power generation. The study evaluates how this device c
