Scientists in the United States have developed a groundbreaking solar panel that continues producing electricity long after the sun goes down. Instead of relying on sunlight, this new technology captures the infrared heat that radiates from Earth into space at night—turning the planet’s natural cooling process into a clean, renewable energy source. It’s a major step forward in solving solar power’s biggest limitation: nighttime darkness. • These “night solar panels” use thermoradiative cells, wh
