New essay The Lost Inventions of Buckminster Fuller Part 3 of 3 now online for free.

"Inventions, the Patented Works of R. Buckminster Fuller" is a good introduction to Fuller’s many inventions. It is the basis for this overview of Fuller’s patented work. But "Inventions" does not include all of Fuller’s inventions, nor are all the inventions in "Inventions" by Fuller. Some inventions relevant to Fuller’s work are not included in "Inventions." Part three this three-part essay features the lost inventions of Buckminster Fuller, works that were not patented or which do not appear in "Inventions," and works that should have been in "Inventions" but were not.
