Is my generator big enough?

Hi,

Here is why you loose wattage from a generator:

I am not sure if I understand how this data relates to the output of the generator. Generators (portable power plants, to be technically correct) consist of two separate parts, the actual generator that produces electricity and the motor that turns the generator. The output of a generator is related to the output capacity of the actual generator, not the torque capacity of the motor. As the amperage draw on a generator increases, so does the torque required from the motor. Portable power plants have a governor that automatically increases the amount of fuel to the motor as the torque requirements increase. So the reduced energy of propane vs gasoline have no direct correlation to the output capacity of the generator. It just seems to me (and I am probably wrong), that with propane, the motor would just consume more fuel to achieve the torque necessary to achieve the maximum potential of the generator.
