....How about you go read the MHD paper i shared to you?
I actually did have a look just out of morbid curiosity, wondering where you make all this stuff up from. To summarize:
1. MHD is not a fundamental source of power, despite the term 'self-sustaining dynamo'. This is just a conversion of forms of energy, a way of, for example, generating heat from mechanical motion on a huge scale. And it isn't a new concept at all. Nobody has proposed MHD as an energy 'source' because they all understand where the energy is coming from--except you.

Many decades ago cosmologist Sir Frederick Hoyle stated that he couldn't disprove (with contemporaneous measurement) that the sun was powered by a giant coal fire. Modern experiments with neutrinos have shown that there is a significant amount of fusion energy produced in the sun, but the experiments don't quite correlate between our models of neutrino behavior and the calculated energy output. So there's room to jump in and claim that the difference is made up by some other energy source. But.....
3. I don't think anyone credible that has done any math is supporting the claim that any significant part of the suns energy is coming from the source you claim and...
4. Even if it were, it would only happen in a large accretion-disk structure like a solar system. You couldn't reproduce that effect in your man-made reactor because your MHD magic still needs an original external energy source.
But I doubt you actually understand any of that.
