Abandoned Mines May Be Repurposed as Gravity-Powered Batteries

Credit: PixabayA gravity battery generates electricity by releasing a heavy load, converting potential energy into power when grid demand is high. When surplus energy is available, the system lifts the load back up for future use.A common example is pumped-storage hydroelectric systems, where water flows downhill to generate power and is pumped back up...

Guiding Electricity Through the Air Using Ultrasound Pulses

Plasma sparks naturally (left) and ultrasound-guided (right)Josu IrisarriElectricity is naturally unpredictable, typically requiring wires and circuits for control. However, researchers in Europe and Canada have successfully directed sparks through open air and around obstacles using ultrasound waves.In open air, electricity naturally spreads in unpredictable directions—much like a lightning bolt. Its path is influenced by...
