The interesting and fascinating physical phenomenon of superconductivity appears, until now, only at very low temperatures and therefore its technical application is limited to relatively few areas. If it is possible to create materials which are superconducting at room temperature, then this could initiate a revolution in technology. More than 10 years fundamental research, experience, knowledge and ideas in the field of special materials (oxides) lead to the conviction that superconductivity at room temperature is possible, and together with Global Scaling - a new knowledge and holistic approach in science - to an extended approach on the search for room temperature superconductors. This presentation is divided into a main part (28 pages) and an appendix (38 pages). A content overview of this presentation is shown on the following pages 3 and 4.
