"2X more efficient, scalable, cooler...  Majorana fermions... layering superconductor with fferromagnetic insulator, applying tiny magnetic field... universal Meissner screening effect... asymmetry in way magnetic field enters superconductor increase efficiency to >50%... edge asymmetries, ubiquitous Meissner screening effect and vortex pinning together produce diode effect... ferromagnetic insulator diode effect maintained in absence of external magnetic field... rectification direction programmed by remanent magnetization layer"
