Weird Technology or Startup Ideas?
What are your weird startup or technology ideas, things that would be cool but that wouldn't necessarily be profitable or possible to build or otherwise practical.
I think that packet-switched pneumatic tubes could be interesting. Last time humanity tried pneumatic tubes we didn't really have packet switching, or electronics that could wirelessly read labels off of fast moving packages. I think a new pneumatic tube network with a simpler network topology (ring networks?) could do very well in urban cores.
