I still am trying, with yet another idea. If you object, please make it substantive like 3D OZ's objection above, not merely abusive about what I have been smoking. OK, on to the idea. It is a project that can be done now. Use a 3D printer to experiment with geometric shapes of objects that interlock or entangle with each other. Once an effective shape has been found, 3D printing has completed its job. Use 3D printed models to patent the shape. Develop applications or license the patent to application developers.

Application 1: a coarse powder that promotes blood clotting. Potential beneficiaries include hemophiliacs, burn victims, surgery patients.

Application 2: sealants. There are many varieties of sealants. I think some still use asbestos, despite being carcinogenic.

Application 3: riprap. Global warming will cause more severe weather, increased coastal damage from storms.
