The Fuller Scale is a unit of humanitarian impact, inspired by Buckminster Fuller, the great American champion of invention as a moral good. It is by definition the impact of all of Fuller's inventions of his long life. Public Invention is a 501c3 public charity, but perhaps more engineering than science. We have created “The Fuller Scale“. It is in a GitHub repo that you can fork. Please share it and its diagram is Free-libre open source content.
