New grid-scale battery sites in Scotland are stabilizing the power supply with their ability to quickly inject power and current during emergencies, just like fossil fuel plants do. One site already proved its worth when it leapt into action after a wood-burning generator unexpectedly shut down. https://spectrum.ieee.org/grid-scale-battery-scotland?utm_source=mastodon&utm_medium=social&utm_campaign=fedica-Mastodon-Daily-Pipeline
GPS systems can be jammed and spoofed. Quantum gravity sensors can't be fooled. A prototype tested in Australia provided a ship with accurate navigation with no GPS sensing for 144 hours. https://spectrum.ieee.org/quantum-gravity-sensor?utm_source=mastodon&utm_medium=social&utm_campaign=fedica-Mastodon-Daily-Pipeline
