In my opinion, this would be one of the highest hanging fruit, if not the highest. This has been in research & development for many decades, and currently multiple dedicated scientist teams in a number of countries are building the next generations of various types of experimental fusion reactors. Those are still quite far from  becoming fully functional for power generation.  This is nuclear fusion physics and has little, if anything at all, to do with what Pyrogenesis is currently doing and currently has experience in. Once again, in my opinion. 

Having said that,  Pyrogenesis has so much potential already and much more to look forward to.
