. In this paper, we present a concept for a new class of quasi-isodynamic (QI) stellarators leveraging HTS technology to overcome well-known challenges of a tokamak. This class of QI-HTS stellarators, labeled Stellaris, is shown to achieve an extensive set of desirable properties for reactor candidates simultaneously for the first time, offering a compelling path toward commercially viable fusion energy. (…)

The physics design point proposed in this study provides a maximum of 2.7 GW of fusion energy, which – together with power multiplication in the blanket – results in about 3.1 GW of thermal power for the plant. It is worth noting that the machine presented here will similarly be able to operate at lower total power, though likely at the cost of economic attractiveness. We estimate a required regular maintenance interval of four to six years for scheduled component substitutions, given structural degradation of the first wall. (…)

Stellaris is a first-of-a-kind concept for a high-field, QI stellarator fusion power plant. It combines significant physics performance improvements, an integrated and self-consistent engineering feasibility study, and novel concepts for key subsystems and operations. Due to the QI symmetry of the magnetic field, Stellaris is designed to operate as an intrinsically steady-state device without disruptions. (…)

. Until now, no single consistent stellarator reactor study has been presented that fulfills all relevant performance aspects of stellarator configuration simultaneously, including an engineering feasibility analysis that builds credibility for a reactor candidate. This paper aims to address this gap, suggesting a new stellarator concept alongside a broad range of analyses targeted at indicating viability for a power plant prototype.

Nach deiner Logik müsste das ja dann rauf gehen,

Schau dir mal deinen eigenen Link an. 2007 138 MT, steigt auf 167 MT bis 2013, sinkt auf 151 MT 2018, 2020 dann nur 96 MT, 2022 119 MT. Das ist nur die Braunkohle. Der Einbruch 2020 ist auf Corona zurückzuführen.

Der Punkt bleibt, dass der CO~2~-Ausstoss erst ab 2018 deutlich abnahm, trotz starkem Ausbau von Erneuerbaren.

Ich finde den Weg, den wir gegangen sind gut und mittelfristig wirtschaftlich besser

Ist halt für CO~2~ und damit das Klima deutlich schlechter.

ungelösten Müllproblemen

Kohletagebau verändert die Landschaft massiv, zerstört Lebensräume und hinterlässt eine gefährliche Wüste.

Unterirdische Minen haben auch gigantische Folgekosten. Im Ruhrgebiet müssen rund um die Uhr massive Pumpen laufen bis in alle Ewigkeiten, damit das Land nicht absäuft und das Grundwasser nicht versalzt.
