AI-Controlled Fighter Jets May Be Closer Than We Think — and Would Change the Face of Warfare
Could we be on the verge of an era where fighter jets take flight without pilots – and are controlled by artificial intelligence (AI)? US R Adm Michael Donnelly recently said that an upcoming combat jet could be the navy’s last one with a pilot in the cockpit.
AI and the Future of the U.S. Electric Grid
Despite its age, the U.S. electric grid remains one of the great workhorses of modern life. Whether it can maintain that performance over the next few years may determine how well the U.S. competes in an AI-driven world.
Using Liquid Air for Grid-Scale Energy Storage
New research finds liquid air energy storage could be the lowest-cost option for ensuring a continuous power supply on a future grid dominated by carbon-free but intermittent sources of electricity.
Enhanced Geothermal Systems: A Promising Source of Round-the-Clock Energy
With its capacity to provide 24/7 power, many are warming up to the prospect of geothermal energy. Scientists are currently working to advance human-made reservoirs in Earth’s deep subsurface to stimulate the activity that exists within natural geothermal systems.
Experts Discuss Geothermal Potential
Geothermal energy harnesses the heat from within Earth—the term comes from the Greek words geo (earth) and therme (heat). It is an energy source that has the potential to power all our energy needs for billions of years.
