Air-mixed frost shelters derive their thermal energy from natural inversion. The world is moving towards stationary machines. Now another mode of operation is becoming apparent. Smoke is merely an illustration of heat propagation. Simple physics itself becomes clear, yet a wonderful happening unfolds. I leave it to the viewer to discover. In a way, this is how the 'wasted' energy developed on the surface of the earth, which the dying inflorescence so badly needs, can be transferred back.

 The heat exchange of air particles takes place much more slowly than we think. This can be called thermal insulation: for example, soil that has cooled to -9 °C sometimes doesn't even cause frost damage to the canopy overnight. Most of the ground surface heat generation (antifreeze candles, buckets, gas burners, exhaust gas, etc.) is above the growing zone of the plantations. This can be seen, for example, in the horizontal smoke propagation of village chimneys. The F-AirGo V2021, together with the heat gain from inversion, also RECOVERS this wasted/radiated heat, circulates it and KEEPS it in the blooming zone! That is what the film is about. Life-saving kJs can be trapped. Look at the smoke...
