The present invention provides method, apparatus, and system that generates and uses a motive and other force by introducing a plasma environment into an asymmetric capacitor (2), resulting in a significant gain in force. This extraordinary increase in force allows the use of ionic motive and other forces to enter the realistic and practical application realm.

Therefore, Bahders article discusses the lightweight effects of. Revista Ingenieras Universidad de Medelln a conventional capacitor is a passive component that can store electric energy, consisting of a pair of conductors separated a distance that allows the presence of a dielectric between them. mostly neglecting border effects. Similarly, the mechanical force between plates can be calculated. The present work intends to identify the nature of the propulsive force that occurs during a positive corona discharge in nitrogen gas around an asymmetric capacitor geometry. The ionic drift transport assumption leads to the correct order of magnitude for the force, however, it is difficult to see how ionic drift enters into the theory.

During that time, I learned about the lifters that people were playing with and asymmetrical capacitors in general, and I decided to developed my own Method of Moment code for calculating the net force on a asymmetric capacitor discretized with a fine grid. Peter, I like your dielectric and potting approach, ex probably missed this point. I do however have doubts about the way gravitec tested that device. The purpose of this paper is to present in general an asymmetric capacitor system with electrically neutral external metallic cover. This system according to the (1, 2) are in force, i. on the basis of the classic solution of the field of fig. In section 3 we describe a simple model which allows the calculation of the propulsion force F L due to the corona wind in the case of a typical asymmetric capacitor gap.

Similarly, the mechanical force between plates can be calculated assuming identical cross sections. Generally, this effect depends on geome capacitor is observed when energizing a pair of electrodes with a voltage in the order of. Clearly the force due to ionic wind is at least three orders of magnitude too small to account for the observed force on an asymmetric capacitor (in air). There is another type of classical transport: drift of charge carriers in an electric field. The present work provides a detailed analysis of already published reports on the observation of an anomalous force in a vacuum associated with vacuum sparks in asymmetric capacitors charged with constant high voltages. 30 kV) is applied to a capacitor whose electrodes have different physical dimensions, the capacitor experiences a net force toward an asymmetric capacitor.
