Here such motion can be practically applied to the following:

(a) To the liquefaction of coal or carbonic-acid-bearing minerals by way of cold (cycloid) systems of flow, e.g. the generation of incombustible, gas-deficient and highly expansive, dynagen-rich 'explosive' water and drive water with the aid of Repulsators for the purpose of producing highly expansive pressures for driving machines of all kinds.
