The final design "mule" is making it's rounds with their demonstration vehicle. I am told that productions units are planned for around early May.
Larry, aesthetically it is very similar to the El Diablo, and a good part of the frame is outwardly dimensionally similar. However, the silencer, waterbox, and the addition of a heat exchanger system make for some significant differences. The waterbox surrounds many of the heated by-airflow components, providing a pre-heat for the last stage wherein the water flow goes through a mixed exhaust exchanger. The system is a combination heat bypass/solution flow dumper type, but instead of lost (filling the wastetank), the bypassed water goes back to the open water box.
