Incorporation of AC component into the current improving the total efficiency, reducing electricity consumption and greenhouse gas emissions

Background Aluminum smelting is a highly energy-dependent process which consumes vast amounts of electrical energy, between 2-3% of worldwide electrical usage. Energy costs of aluminum smelting make up around 25% of manufacturing costs to produce primary aluminum (as opposed to recycled). Resistive loss during smelting is the primary source of...

Novel Transcutaneous Energy Transfer (TET) Device

Applications: A ventricular assist device (VAD) is an auxiliary blood circulation pump. It is implanted to assist the left, right or both ventricles to enhance circulation. The power source is worn externally by the patient with a cable going through the skin. The opening in the skin becomes a portal for serious infection which may also travel...
