snow machines with a generator / engine concept for the production machine snow in snow making apparatuses, wherein in a first mode is a propeller / fan (4) directly via a water wheel (6) is being operated, so that this requires no electrical energy is required and, via a in the production of the snow propeller machine carrier integrated generator (2), which, by way of the water-wheel (6) is driven, there is an electrical power for all the other for the mechanical snow production of necessary components such as a compressor (9) for generating compressed air or also for the generation of light is used, wherein excess energy for energy recovery can be supplied to the electrical power supply system, and wherein in a second mode of the snow machines on conventional snow making apparatuses can be operated in the normal operation, in that for this purpose of the water-wheel (6) from the generator (2) is coupled, with the generator (2) then functions as a normal three-phase motor and the propeller / fan (4) operates.
