Well, more or less. Engineers have figured out how to store electricity in a thin piece of glass sandwiched between metal plates.
It's a newfangled capacitor, actually, and capacitors are known for their ability to release large bursts of electricity and work over and over and over. It uses glass called barium boroaluminosilicate, also used in flat-panel TV displays, and holds more than twice as much charge as polypropylene, which is used in capacitors today.
Hope is the devices will eventually provide bursts of energy to run things like heart defibrillators or electric cars.
