I might be wrong. But from his last post, the designs are not far from what we have. I think it is the type of refrigerant he uses for his autocascades.which most of us could not have access to, or do not have enough knowledge on the purpose of it. For example R123 was used in most of his autoc but most of the autoc in XS do not use such refrigerant.Maybe because we do not know its properties enough.
But still i would like to know how far his designs are from those in XS but i would be more interested to know the use of some of his unusual refrigerant like R123.

im interested in direction of flow on the hxs.
ie cc1 cc2 and coaxial hx
ie evap bottom up with high stage entering top exit bottom.
i cant confirm but it looks like one of the cc's flows high stage entering bottom??
