Theoretical Fusion Advancement?

I think the approach here is quite promising. For decades plasma physics has been about removing impurities from these machines. This seems to be about utilizing singularities to advantage rather than eliminating them. And this appears very much to be what we see normally occurring in nature.

It should be understood that the whole rationale of the hoary Malthusian worldview of limits to growth will implode when fusion energy becomes a practicality. So we will not have to throw humanity to the wolves in the name of needed austerity as we now so senselessly and piteously are.
