The Generac Standby Generator, 40 kW | 120/240 V 1-Phase is a 40 kW liquid-cooled standby generator built for commercial standby duty.  It runs on natural gas or liquid propane already connected to the property, so there is no fuel to store or carry.  It starts automatically within seconds of an outage and returns to standby once utility power is restored.
