Ask HN: What should I do with a grand idea?
Implementing it would involve some research, and quite large-scale transport engineering. It would also be likely to encounter political opposition in some places, but it would be environmentally clean, and I think it would be wildly popular.
This would be a long-term thing; I'm retired, I'm not up for trying to kick it off, let alone see it through.
I don't know if there is prior art.
How should I proceed?
