A decent Dyson shell concept; the best part of it is the better gravity on the outside. On the other hand, the stress analysis shows that no real material could be used to build it in the 1m thick design envisioned. One of these days I have to get around to writing a paper about building Dyson shells onto the surface of red dwarf stars. The gas pressure of the star would support a thin shell, and a number of red dwarf stars have surface temperatures lower than refractory materials like carbon and tungsten. The surface gravity would be too high for human life, but it would make a heck of power plant. Too many papers to write, too little time...
