    A Working Radiant Free Energy System By Ossie Callanan – January 2007 A Working Radiant Free Energy System Introduction - By Ossie Callanan I believe I may have this radiant energy system worked out to the point where anyone can build it and when you build it‚ all of it‚ it can provide you with free and continuous energy. There are two sides to it and just having either side is no good‚ you must have both. Of course‚ one side is the motor/charger side‚ and the other is the battery and accumulatorconverter

    Eddy Current 1. The principles of eddy current testing depend on the process of electromagnetic induction. 2. This process includes a test coil through which vary or alternating current (AC) is passed. 3. A varying current flowing in a test coil produces a varying electromagnetic field around the coil‚ As shown in this diagram Amperage * # of coils= strength of magnetic field 4. The electromagnetic field produced around the coils is directly proportional

    To estimate impedance function‚ distance as a proxy of travel cost between pairs of origins and destinations is calculated by ARC GIS 10.2 which considers the length of the shortest available route. To calibrate the best impedance function‚ the frequency distribution of walking trips is plotted against distance. By fitting different types of functions (i.e.‚ exponential‚ multiplicative exponential‚ linear‚ logarithmic‚ polynomial‚ power) and comparing standard error of the estimates’ values‚ the
