In time I'll publish a paper and technical report. In a little more, I'll show a prototype. But I do have my hands fairly full!

I don't usually work from the literature (it is hard to access papers outside of academia, and they're usually weird, abstract, hard to read, and miss the point anyway) so I work from the first principles.

But at a high level, imagine either an Ericsson or Carnot cycle, (dependent on materials), where high temp, high pressure heat addition is contiguous combustion during expansion, and the isothermal compression is a secret sauce :-)
