Moving near light speed lets quantum sensors squeeze more thermal energy, breaking old efficiency limits.

Speed is a power source too. A quantum heat engine flying near light speed 'sees' temperature differently and can extract more work than it’s allowed. Someday, interstellar probes might power themselves this way.

🎯 In interstellar space, such an engine could recharge from the cosmic microwave background—the cooled light of the Big Bang—simply by moving at high speed.

🎬 The idea of harvesting energy from the vacuum isn’t new: it pops up in Stanisław Lem’s 'Star Diaries' and other sci-fi stories.
