If everyone went 100 percent geothermal today, Earth’s store of thermal energy would still outlive the sun. Thermal vents in Iceland’s Kerlingarfjöll Mountains. The Earth contains a mind-boggling amount of heat energy below the surface. PHOTOGRAPH: MARTIN ZWICK/GETTY IMAGES Pop quiz: Of all the different ways of generating electricity or […]

Stock photo depicting a flexible solar cell. Scientists from the RIKEN Cluster for Pioneering Research and RIKEN Center for Emergent Matter Science have succeeded, in collaboration with international partners, in creating an ultrathin organic solar cell that is both highly efficient and durable. Using a simple post-annealing process, they created […]

Researchers use a ferroelectric glass electrolyte within an electrochemical cell to create simple self-charging batteries. A new type of battery combines negative capacitance and negative resistance within the same cell, allowing the cell to self-charge without losing energy, which has important implications for long-term storage and improved output power for […]

This tiny wing could someday be used in robots or devices to harvest solar energy.

Now, researchers reporting in ACS Applied Materials & Interfaceshave made artificial wings that are […]

A new bendable supercapacitor made from graphene, which charges quickly and safely stores a record-high level of energy for use over a long period. Credit: Dr. Zhuangnan Li (UCL) While at the proof-of-concept stage, this new bendable graphene-based supercapacitor shows enormous potential as a portable power supply in several practical applications […]
