Question

I am very interested in building one of these for my small grain farm and have the tools and material to build one. I'm curious as to if the machine as described here was ever operated. The drawings are hard to put together into a coherent picture of the final machine, especially the rotor design. It all looks like drawings out of an old farmer's notebook from 1980, was this the machine tested or was it reimplemented from his drawings?

There is a mention of it being operated at New Hampshire - any pictures of the final machine or reports of performance would be quite valuable!
