Listing of all scientific projects in the world
It may start as a hobby then become something else.
The idea is to build a register of all current scientific projects in the world, in order to avoid multiple projects/funding on the same field. Image labo A and B working on the same project, getting X financing each. What a loss of money, time and talent. Instead, B should work on another project, and A would get 2X funding and 2X talent. Let's change the world!
