You really expect me to believe that a small-diameter single-stage centrifugal gas turbine gives you 30% efficiency? 30% efficiency equates to a heat rate of 11, 376 BTU/kwh.
If a company is not willing to guarantee a heat rate they are selling snake oil.

0.327 lb/HP-hr equates to 6,540 BTU/HP/hr or 38.9% efficiency To get better thermal efficiency you’d have to go to a LM6000 (54,000 shp) to beat this medium speed engine.
People do stuff for a reason, sport. Gas turbines have their niche but automobiles, trucks and locomotives aren’t a part of it. And professionals don’t believe company propaganda unless the company is ready to back up what they say.
This Capstone outfit looks shady to me.
