I believe they retrofitted a diesel-electric to putt along with the
Sterling, or go full speed with the original propulsion. I just don't
recall if they even mentioned the transmission, or if they were using the
retrofit to generate electricity. They did mention they were using kerosene
and bottled O2 as a fuel.
