💡Technology to store heat in the moon's regolith is being tested on Earth using sand-filled cylinders
🌙Regolith stores heat and can be used as an energy source during lunar nights
🚀Possible approach includes using a rover to pile regolith on a heat exchanger on the moon's surface
🌌As lunar infrastructure grows, long-term heating via energy storage could become more common
🌏The technology could have applications on Earth for renewable energy storage
