Re: Von Neumann cycle stationary plant details

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?

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.

Cheers,

Douglas
