(b) Two different types of flow, which we shall describe as F1 and F2.

Through these hitherto unknown forms of temperature and motion the substance in question (i.e. water or air) is decomposed, transformed and built up. In this way, through appropriate regulation, elemental energies are freed. Suctional and pressural forces come into being, which in my apparatuses evolve along a common developmental axis and represent an entirely new means of motion and propulsion.
