I have produced an EXCEL spreadsheet for examining what is happening in the material development of our civilization and so expected future trends. I have done examinations for the global, US, Chinese and Australian economies. Based on my experience, I believe it will be a powerful, transparent tool to aid sound decision making.
I want to make the G&SC spreadsheet available globally so a range of experts can contribute to estimating the values in appropriate cells while using the associated charts as feedback. These estimates need to be backed by explanatory comments and appropriate references. This wide-ranging input will help to improve its credibility as well as providing better understanding of the complex issues.
I know that I can forward the spreadsheet using the Routing procedure. However, there may be means that I am unaware of that will be a more efficient way of having a central version of the spreadsheet which is being continually refined while participants can also have their versions so the can carry out trials.
