A high-altitude unmanned-aerial-vehicle prototype, powered by solar panels and batteries, performs functions commonly attributed to spacecraft flying in low Earth orbits.
As embedded systems and IoT devices push more into applications in remote locations, designers are looking at alternative means to portably power them.
After decades of research and investment, silicon-based solar cells are close to their maximum theoretical efficiency. Will perovskite be the go-to material solution?
A 5-MW/15-MWh liquid air energy-storage (LAES) system supports solar and wind renewable power and provides reserve, grid-balancing, and regulation services.
Several published scenarios claim that a 100% renewable electricity system is achievable. But many questions remain as to whether these claims are valid.
Systems that extract waste heat from industrial processes and use it generate electric power now employ chemical-electromechanical technology.
By shaping thermoelectric materials into ultra-thin nanowires, researchers were able to efficiently generate electricity from waste heat.
A heat-activated process converts waste lignosulfonate from papermaking production for use a cathode material in rechargeable lithium-sulfur batteries.
Using additive manufacturing, researchers devised a way to remotely sense motion via Wi-Fi backscatter, without any interconnecting wires or need for power at the sensor.
