Nature produces energy by slow, cool, implosive means — by a centripetal inward motion, while our present culture uses explosive centrifugal (outwards) movement, which is wasteful and many times less powerful and effective. It also uses up the Earth's resources and pollutes her ecosystems. This volume describes different kinds of energy machines which depend on the principle of implosion: a spring water-producing machine; a tornado home energy generator; a Klimator which produces mountain-quality air; the biotechnical submarine; a technique for producing power from ocean deeps.
