In Nature there are only structures and orifices. From these arise all forms of materialisation and dematerialisation, if orifices and vessels are organised in an inversely symmetrical configuration and within them the reciprocal gaseous substances are correctly dosed. Pressure and suction, and most important of all, the temperature-gradient should be aligned in the right sense (+ not -), through which the desired energy is freed at the point of intersection.

This can be accumulated if the thing is cooled during its motion, becoming homogenously structured in the process. In this manner it is even possible to decompose ordinary air into animalistic electrical essences, or to produce an artificial thunderstorm, whose transformative essences discharge into metal conductors, calling into being a physical vacuum with which a thunderstorm can be produced in the tube, whose power exceeds that of a cyclone. While it is still necessary to use small quantities of earthly substances in the artificial production of petrol (gasoline), no fuels of any kind are needed to operate the air-turbine[4]. This will avert the crisis that will inevitably ensue if nature-alienated humanity continues to combust substances in its machines, which are preordained by Nature for the provision of food. The seemingly remarkable behaviour of liquids under the influence of light is the totally natural permanent condition of the eternal 'Arising' and 'Passing Away', of the evolution from small to large and vice versa, whose vital harmony Goethe has already explained to us so beautifully that all we need to do is read his works so as to create the perpetual interaction required by all molecules in order to exist in a state of well-behaved order.
