No, this is not about Asimov’s 1st law of robotics (”A robot must never harm a human, or through inaction, allow harm to come to a human”). It’s about the 1st law of thermodynamics.
The 1st law of thermodynamics is stated quite simply: the total energy of a closed system never changes. By “closed” we mean that nothing enters or leaves the system. Another way to state the law is that energy is conserved. You can’t create it from nothing, and you can’t make it disappear. It can change from one form to another, but the total of all energy never increases or decreases.
