   The idea is fascinating, at least to me it is.   
      
   Aircraft propulsion plants are all about the highest possible combustion   
   intensity in kilowatts or even megawatts per cubic centimeter. But then so   
   are foundries! Why not combine the two sciences?   
      
   Tonight I looked up the article on Mach diamonds. Across the plane of the   
   Mach disc temperature increases quickly, and an awful lot, in very little   
   space.   
      
   There should be some way to wrap a Mach disc around a crucible holding   
   recyclable steel. This would be accomplished by suitable shaping of a   
   nozzle, a post nozzle refractory insulated area, a crucible, and even   
   shaping the gas flow perhaps by r inserting mixers.   
      
   I believe, just from what I've read about Mach diamonds, that smelting and   
   refining steel, at least from recyclable steel, using a combination of a   
   turbo generated high enthalpy gas flow, along with a turbo generated   
   electric Arc, and I should mention that many of our American steel products   
   are refined, along with a suitable supply of injectable air for the   
   Bessemer refining step in which carbon is extracted from melt, ... Will be   
   possible, using only coal gas or even methane is fuel, with beneficial   
   impact on overall industrial CO2 and other types of pollution affecting   
   that one crisis which we all share,   
      
   Global warming.

A nearly new copy   
   of Sorenson's book arrived just the other    
   day. 

The idea is fascinating,   
   at least to me it is.

Aircraft   
   propulsion plants are all about the highest possible combustion intensity in   
   kilowatts or even    
   megawatts per cubic centimeter. But then so are foundries! Why not combine the   
   two sciences?
