That's really cool. Do you know of any sources for his inspiration other than JS? And any standout memories of your uncle you can share? He seems like a really intelligent guy. It'd be neat if some scaled-down version of this could be tested without creating so many waves.
He's definitely bright. My Dad and he worked together for many years, though not on this project. When I asked my Dad about it he said, “no comment.” Ha.
I confess I don't know other sources of inspiration, though I'm certain he's very familiar with other engineering efforts of similar kind. The reporting in this article is pretty sound; he's drawing much of his inspiration from an abstract document.
