Batteries on wheels

New charging technology to make e-cars suitable for mass use as mobile power storage units. Bidirectional charging enables electric vehicles to be both charged and discharged as needed. E-cars can…

Energy-storing supercapacitor from ancient materials

Made of cement, carbon black, and water, the device could provide cheap and scalable energy storage for renewable energy sources. Two of humanity’s most ubiquitous historical materials, cement and carbon…

Fusion model hot off the wall

Predicting molecular rotational temperature for enhanced plasma recombination. Humans may never be able to tame the Sun, but hydrogen plasma — making up most of the Sun’s interior — can…

Going the distance for better wireless charging

Accounting for radiation loss is the key to efficient wireless power transfer over long distances. A better way to wirelessly charge over long distances has been developed at Aalto University….

New tech brings resilience to small-town hydropower

Idaho National Laboratory (INL) celebrated the ribbon-cutting of its new Microgrid in a Box, which was deployed in partnership with the Fall River Electric Cooperative at its hydropower plant in…

Power electronics for novel heat pumps

… achieves efficiency of over 99.7 percent. In the Fraunhofer lighthouse project ElKaWe, researchers are working on the development of electrocaloric heat pumps as an alternative to the currently prevailing…
