A Sustainable Future Model of Energy and Mobility — •Michael Düren — Justus-Liebig-Universität Giessen, Germany --- Laureate of the Robert-Wichard-Pohl-Prize 2021

The future of our civilization is challenged by overpopulation, the reduction of biodiversity and climate change. Energy and mobility are preconditions of a modern society where we as physicists can search for an optimum future model. Solutions for energy supply that work on a global scale are those renewable sources, that are abundantly available: solar, wind and marine power. To minimize resources and waste, energy should be harvested in the most viable places. In a physicist's world, we should start to manage the energy flow of our planet globally and transport energy across borders and continents using high voltage DC lines and other energy carriers.

Electrification of mobility is another must of a future society that minimizes resources and optimizes efficiencies. From simple physics arguments follows that electric railways can save a factor of 10 in energy consumption compared to the current individual mobility. If rail transport is taken seriously as a future mainstream of transport, it is clear that the current automobile infrastructure has to be reused to minimize additional land consumption. The author proposes a system of speed-trams that run on the 'Auto-Bahn' with batteries and overhead lines. Their batteries are simultaneously used as short-term storage to stabilize the national energy grid.
