A heat engine is provided with twin crankshafts and coil shaped power elements mounted between each of two crankshafts. Each power element moves upward and downward, parallel with the surface of a tank of hot water, in which the engine is partially submersed, so that every part of the power element is allowed to remain submersed in the hot water for the same time interval so as to achieve maximum rotating power.       Recently Added Patents Memory system having high data transfer efficiency and host controller Automatic correction of application based on runtime behavior Rapid local address assignment for wireless communication networks Anatomic spinal implant having anatomic bearing surfaces Brazing system and method Staurosporine derivatives as inhibitors of FLT3 receptor tyrosine kinase activity Wall mounted modular workstation system and method   Randomly Featured Patents Expandable dual dental impression tray Radiation image sensor and scintillator panel Optimization of subnetwork bandwidth based on desired subscription rates Slip-fit handle for hand-held instruments that access interior body regions Enclosure assembly and method of constructing same Method for shaping an airfoil Water soluble binder overcoat on vesicular element containing N.sub.2 -releasing agent Subsurface freeze zone using formation fractures Disk array device managing cache memory by dividing cache memory into a plurality of cache segments Switchable battery charger circuit © 2006-2008 PatentGenius.
