Abstract: Air cooling devices driven rotational power of electric motors to expand air to thereby produce and supply cooling air. An air cooling device includes a power transmission device for increasing a rotational driving force of an expander that is disposed between the expander housing and an electric motor and for separating the expander from the electric motor. The power transmission device generates rotational magnetic field by receiving rotational power from the electric motor or receiving rotational power from the electric motor and external electric power. The rotating magnetic field generates a rotational force by interacting with magnetic field, based on attraction and repulsion forces. The air cooling device increases rotation speed and force when it transmits the power. The air cooling device increases a flow rate, and expands air adiabatically, thereby supplying cold air with high air density.

Abstract: A fluid vapor distillation apparatus. The apparatus includes a source fluid input, and an evaporator condenser apparatus. The evaporator condenser apparatus includes a substantially cylindrical housing and a plurality of tubes in the housing. The source fluid input is fluidly connected to the evaporator condenser and the evaporator condenser transforms source fluid into steam and transforms compressed steam into product fluid. Also included in the fluid vapor distillation apparatus is a heat exchanger fluidly connected to the source fluid input and a product fluid output. The heat exchanger includes an outer tube and at least one inner tube. Also included in the fluid vapor distillation apparatus is a regenerative blower fluidly connected to the evaporator condenser. The regenerative blower compresses steam, and the compressed steam flows to the evaporative condenser where compressed steam is transformed into product fluid.
