Raphial, let’s start out with an overview the MYT engine, which you’ve made some big claims about in terms of size, performance, and efficiency. What inspired you to develop this?

When I got back from Vietnam, the chaplain said “get busy or go crazy”, so I got busy — I was a sheet-metal worker at the time and I got into drag-racing, and during that period blew up more than my share of conventional engines. Those engines were expensive, complex & difficult to maintain, and I started to wonder if there might not be better way to build a high-performance engine.
