A problem family — different problems, same issues
30 problems across 15 fields
These 30 problems have already been solved technically — the technology works. What blocks them is economics, but 'too expensive' means eight different things. Recycled plastic costs more than virgin because polymer degradation is inherent — the same physics-imposed cost floor that makes PFAS destruction prohibitively expensive. Small modular reactors face first-of-a-kind costs that only decline with deployment. The stewardship-commerce conflict adds a structural dimension: antibacterial drug development collapses because maximizing sales contradicts the public health goal of minimizing use.
The technology works. The economics don't. And 'too expensive' means eight different things — identify which kind you face before choosing a strategy.
