Modular housing that grows with your life. Biggest problem there is effective expansion joints that would hold the houses together. Affordable container ship that is electric. A personal finance software that solves upper-middle class issues (eg. primary income, side business, rentals, etc.). A product/service that makes CROs obsolete in drug development (CROs = 25% of cost of drugs; admin overhead) Idk, those are so…

High Speed Multimedia or HSMM is a mesh network for ham operators. I would be interested in getting into it but the off the shelf equipment is microwave band and does not propagate like 20 meter. So it has a kind of chicken vrs egg problem for now.

That's why I'm thinking just a communication platform. Start small. Rebuild from the ground up. Robustness is more important than any other factors imo. I want something that is near impossible to take down and can reach globally. I would think this would have to be some large mesh network. There's definitely a lot of challenges in just getting text to transmit across something like this. But it has a ton of uses.

Sadly I have but one upvote to give, because making that kind of optimal use of garbage would solve a bunch of other problems.

It's also such a rich technical problem, that spans every sort of engineering, from machine learning to robotics to chemistry and materials engineering. And it's like, purely a technical business. If you have a company that can "buy" garbage for $X and sell your outputs for $Y > $X (+costs), you don't need to deal with politics and lobbying and building buzz.
