Energy Efficiency

Stanford University researchers have developed a machine learning-based method that cuts battery testing times by 98 percent. The team says that their A.I. technique could lead to a future where an electric battery is recharged in the time it takes to stop at a gas station. Watch...

Our lead INSIDER story today demonstrated the power of a droplet energy generator – specifically the system’s ability to light up 100 LEDs with just a small amount of water.

This month’s Tech Briefs featured a potential alternative to the air conditioner: A painted-on polymer coating that can cool down a building.

Today's lead INSIDER story demonstrated how ocean waves can be used to turn seawater into freshwater.

Car engines, laptop computers, cellphones, and refrigerators all heat up with overuse. That heat can be captured and turned into energy using a method that produces electricity from heat. The technology uses a silicon chip, also known as a “device,” that converts more thermal radiation into...

A 2019 Tech Briefs story demonstrated a plastic-like, flexible nanongenerator that creates electricity from falling snow.

The widespread adoption of thermoelectric devices that can directly convert electricity into thermal energy for cooling and heating has been hindered, in part, by the lack of materials that are both inexpensive and highly efficient at room temperature. A new material was developed that...

Robert F. Shepherd is Associate Professor of Mechanical and Aerospace Engineering at Cornell University in Ithaca, NY. He is leading a team exploring the use of hydraulic fluids in soft robots to also serve as a source of energy.

Scientists are studying bismuth ferrite (BFO) material that has the potential to store information much more efficiently than is currently possible. BFO could also be used in sensors, transducers, and other electronics.
