The document compares a conventional 1 MW generator to a ReGenX 1 MW generator. The ReGenX generator requires no additional mechanical input power when under load compared to no-load, while the conventional generator requires 1 MW more input power under load. Both generator types produce 1 MW of output power under load but the ReGenX generator maintains the system speed of 3500 RPM with less than 0.5 MW of total mechanical input power, offering power generation efficiencies over the conventional generator.
