Johnson noise engines, demons; energy dissipation at control and logic operations Papers/results: 1. Electrical Maxwell Demon and Szilard Engine Utilizing Johnson Noise, Measurement, Logic and Control. In the electrical Maxwell demon there are no mechanical moving components, only two forms of energy exist: heat and electrical energy. In the electrical Szilard engine, out of these energies, the output is mechanical energy. It contains no other moving components than the piston. The weakness of the original Szilard engine is avoided: there is no need for the artificial step of restoring the position of the piston to its initial state. Here, this step is an inherent part of the cycle and and the piston produces works during moving in both directions. Click here 2. The ultimate energy-requirement of control (including critiques of related deficiencies in historical approaches to Maxwell demon and Szilard engine), first version presented as invited talk at the conference "All the Colors of Noise", Lecce, Italy, November 2011. Second version published in EPL (June 2012): L.B. Kish, C.G. Granqvist, "Energy Requirement of Control: Comments on the Maxwell Demon and the Szilard Engine" EPL 98 (2012) 68001 (June 2012), Click here > 3. New schemes, purely
