How do free energy machines work?​

Free energy machines do not work. No machine can create energy out of nothing, as this would violate the law of mass-energy conservation, which is fundamental and universal. The law of mass-energy conservation states that mass-energy can never be created or destroyed. It can only be redistributed throughout space and transformed into different states. Mass can be converted to energy, and energy can be converted to mass, but together they must be conserved. For instance, when a positron from the tracer liquid of a medical PET scan hits an electron in the patient's body, the positron and electron completely destroy each other and all of their mass is converted into energy. This energy is emitted as two gamma particles (high energy light) that fly off in nearly opposite directions. The PET machine detects the gamma rays, uses them to pinpoint the location of the positron-electron annihilation event, and therefore discovers where in the patient's body the tracer liquid is congregating. Nuclear bombs and nuclear reactors also convert mass to energy, but the conversion is very inefficient and only a fraction of the bomb's mass is converted to energy. Mass is also converted to energy during radioactive decay.
