Paul's son was intending to pick up where his father left off on this design. The intention behind the design appeared to make sense but what was the result, Jim? Numbers. What happened.  I am not negative to the concepts. As do most M.E. (NOT D.E.) I live in a more positive mindset toward aviation innovation.  Most of the D.E. (certainly not all) I have had to work with definitely have ego issues mostly surrounds a degree of some kind. Some of what I wanted to investigate and never has been done yet might still be worthy in investigating. Paul had results..of that there is no question.   

 I was also involved directly in the Wind Turbine powerplants over the Columbia River..  was part of the engineering team and my LLC was one of the foundation companies that raised the first five machines near Goldendale Washington along with Mariah Energy.  Now there are literally thousands of the larger units as we have also here in Oklahoma both in Washington and the Oregon river basin 800 or so feet below.  We installed the first five on what was at one time the Boeing Mod 5 location.  Take a  goodlook at the Turbine blades on todays machines and you'll see Pauls work also.
