Researchers develop all-weather solar cell that generates power from rain as well as from sun

Green Car Congress

While many technical advances have made solar cells more efficient and affordable, a disadvantage remains in the fact that solar cells produce no power when it’s raining. c), d) The operational principle of the flexible solar cell under sunlight. The droplets are injected by a medical syringe by controlling injection velocity.

Energy Harvesting for Wearable Technology Steps Up

Cars That Think

But we do actually need that energy to be generated,” says Alper Bozkurt, who with Veena Misra codirects the Center for Advanced Self-Powered Systems of Integrated Sensors and Technologies (ASSIST) at North Carolina State University. But solar is just the opening gambit. Leveraging watch tech for…bisons?

Univ. of Texas researchers propose lithium- or sodium-water batteries as next generation of high-capacity battery technology; applicable for EVs and grid storage

Green Car Congress

Researchers at the University of Texas, including Dr. John Goodenough, are proposing a strategy for high-capacity next-generation alkali (lithium or sodium)-ion batteries using water-soluble redox couples as the cathode. The present sodium-sulfur battery operates above 300 °C. Example of a lithium-water rechargeable battery.
