It's a human designed mechanical system that produces more power than it uses. More commonly known as a powerplant. I didn't write the stupid article and you latched onto one word and quit reading without grokking the concept.
There is nothing an ICE motor can do that an electric motor cannot do better...The source of easily stored power is the only advantage it has. And that source is waning.
Mining involves removing stuff from below ground and putting it into commerce at normal altitude. The most successful mines are open pit operations that involve making a wide hole in the landscape and hauling ore and spoil up hill out of the hole to average altitude. A mining truck based around a regenerative electric motor with battery pack will use more power hauling a full load of ore out of the pit than it will regenerate coasting back down hill empty to pick up the next load of ore. Sure ther is an efficiency gain from regen motors on the coast down hill, but in a lot of hilly places like say Greece, commercial drivers often conserve fuel by shutting off the motor and coasting down hill under gravitational attraction.
