. 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.

Kohle schleudert mehr Radioaktivität in die Luft und Umwelt als Atomkraft und auch sonst noch Blei und andere Gifte.

Vergleich auch mal die Anzahl Toten pro Jahr nach Energiequelle. Kohle ist da mit Abstand an der Spitze.

ist nicht steuerbar in der Energieerzeugung, passt daher nicht gut zu Erneuerbaren

Frankreich und Schweden lässt du nicht gelten?

Was sagt denn die Wissenschaft dazu?

https://www.sciencedirect.com/science/article/abs/pii/S0306261918303180

Die Anti-Atom-Ideologie sitzt sehr tief in Deutschland und ist nur teilweise rational wissenschaftlich begründet.

Da hat u.A. auch die Kohlelobby ganze Arbeit geleistet im Schüren von Angst. Politiker haben Karriere damit gemacht. NGOs leben davon.

The Russian economy will collapse, sooner or later.

I agree, but think it's later. Russia needs to lose on the battlefield as well before they stop the war.

Exactly, it can go bat -> livestock/pet -> human just as well.

“Demos gegen die CDU”. Die gab es nicht

Es gab Demos vor der CDU-Parteizentrale und Parteibüros im ganzen Land, teilweise inklusive Besetzung.

Wenn da kein Narrativ gesponnen wird

Natürlich gibt es ein Narrativ.

how Europe should have done during and after WWII

During the same decade Palestinians were displaced in 1948 and Jews were expelled from Muslim countries, millions (Germans, Poles, Ukrainians, Crimean Tatars, etc.) were displaced in Europe. Today their descendants aren't counted as refugees. Poles don't blow up buses in Lviv today. Neither do Germans shoot rockets into Czechia. People lost everything, built new lives, and got over it.

connection between European Antisemitism and Christian Zionism

That exists, but is an alliance of convenience, not friendship. Christian Antisemitism, failure of assimilation, and escalating persecution was the reason Zionism was established in the first place. Jews had to flee Europe or face extinction. Most had no choice but to go to their ancestral homeland.

The mass ethnic cleansing campaign of 1948:

I was referring to how this happened in practice. Many Arab Palestinians had fled their homes before the fighting even started. The well off wanted to sit out the war in Beirut, Cairo, and Damascus. Arab radio had called for civilians to evacuate and wait at a safe place for the inevitable Arab victory. Most had left before Operation Nachshon started. Not every village or town was forcibly cleared. The news of one massacre or destroyed village spread fast and people understandably fled. Most villages that were destroyed, were destroyed after the war to prevent the refugees from returning.

Plan Dalet

Read the original text yourself, instead of relying on misrepresentation after the fact.

It would have meant the expulsion of hundreds of thousands of Palestinians within the area defined as the “Jewish State”

You are so incredibly misinformed by only reading one sided narrative.

Here the original UN resolution 181. Page 138 Chapter 3.1

Citiz1mship. Palestinian citizcns rcsiding in l'alestine outside the City of Jerusalem, as well as Arabs and Jews who, not holding Palestinian citi- zenship reside in Palestine outside the City of Jeru- salem shall, upon the recognition of indepcndenc~, become citizcns of the State in which they are rcsi- dent and enjoy full civil and political rights. Per- sons over the age of eighteen years may opt, within one year from the date of recognition of indepen- dence of the State in which they reside, for citizen- ship of the other State, provicling that no Arab residing in the arca of the proposed Arab State shall have the right to opt for citizcnship in the proposed Jewish State and no Jew resicling in the proposcd Jewish State shall have the right to opt for citizen- ship in the proposed Arab State. The exercise of this right of option will be taken to include the wives and cliildren under eightccn years of age of persons so opting.

Arabs rcsiding in the arca of the proposed Jewish State and Jews residing in the area of the proposed Arab State who have signed a notice of intention to opt for citizcnship of the other State shall be cli- ~ble to vote in the clections to the Constituent As- sembly of that State, but not in the clections to the Constituent Assembly of the State in which they reside.

I highly recommend actually reading the UN resolutions and other documents as they are often misrepresented in the media by both sides.

second-class citizens

Yes, there's discrimination in Israel against Arabs. Similar to discrimination against minorities around the world.

Benny Morris considers Ethnic Cleansing justified

More like he sees it as inevitable. The Jews in Palestine were surrounded by numerically superior forces and feared being exterminated. They did what they had to to ensure their own survival.
