Sehr interessantes Thema.
Aktuell wird ja in Deutschland nur an dem Plasma geforscht, wie man es lange erhält, heiß genug bekommt, usw.
Aber jetzt einen Fusionsreaktor draus zu machen ist relativ einfach.
Ich bin mehr der Meinung, dass der Tokamak sich durchsetzen wird, aber das kann man noch nicht genau abschätzen.
Beim Tokamak ist jedoch nur das Problem, dass man eben das Plasma nicht lang genug heiß und zusammen hält.
Denn man muss einen Strom ins Plasma induzieren, damit dieses dann durch den Stromfluss und das daraus resultierende Magnetfeld sich zusammenhält. Da dieser Strom jedoch nur in eine Richtung fließen kann und nicht einfach wechseln, muss über die Spule, die das Plasma induziert immer mehr Strom fließen.
Indem man nun Mikrowellen nutzt, um diesen Strom auch extern aufrecht zu erhalten, dann hat man die Möglichkeit den Tokamak in Richtung Dauerbetrieb zu bringen.
Dieses Zitat bezieht sich auf eben einen solchen Versuch mit Mikrowellen beim IPP in München. Der Dauerbetrieb beim Tokamak ist also nicht mehr weit entfernt.
So weit es mir bekannt ist, soll beim ITER ja bereits mit Fusion gestartet werden. Dabei wird es sich ja dann herausstellen, ob es möglich ist den Tokamak im Dauerbetrieb oder nahezu Dauerbetrieb laufen lassen können.
Und wenn ITER dann Fusion durchführt, dann haben wir auch radioaktives Material was dort entsteht. :D

Don't you think that a timeline of less than 30 years for having controlled and useable nuclear fusion seems a little bit too short. Since even with ITER or Wendelstein working, we are still far from the industrial applications, aren't we?

Of course, 30 years is a very optimistic approach. I was, more or less, referring to the (theoretically) first successful break-even fusion generator whose model could (hopefully) be applied all around the world.
The first (planned-to-be) functional and break-even Fusion plant (DEMO) might
Which means that"In 30 Years" does, by far, not mean that we would have instant and infinite energy from fusion reaction from that time on - but rather it's more like the first foundation stone laid ... although we're building a giant cathedral from now on. ;)

Okidooki! Thanks for the clarifications. The golden "50 years from now" seems again in order (I hear this since the 1990s :) )

This method is very expensive and does not even pay for itself, unfortunately.

For now.
Nuclear fission isn't "cheap" either, but it pays for itself.
After reaching the point of "break-even" fusion is the much better alternative to fission.

You are absolutely right, this kind of energy is much cleaner, but for many years a cheap solution has not been found.
