"After this brief pointer as to how these gigantic formative and levitative forces can be made use of in the national economy, it should also be mentioned that these 'original' tractive and transportive forces can be applied to the silent, odourless, smokeless, toxic-emission-free propulsion of all types of machine, all forms of conveyance on land, on water and in the air at any desired speed and at negligible cost, for in such machines, instead of resistance, the power increases by the square of the velocity. Now devoid of foundations, the crowning law of fire-spitting technology will therefore collapse upon itself."
