A lot of these feel like trick questions. Which offers more bang for the buck: improving airplane efficiency, or building a global network of high-speed rail?

It matters a lot how much we are improving efficiency, and how complete the "global network of high speed rail" is.
- SirLJ 9y agoA teleport will fix this...
- AnimalMuppet 9y agoDepends on the energy required to run it.
- Terr_ 9y agoLong before you use it for people, teleportation would unlock other capabilities and efficiencies. For example, consider what would happen for nuclear power replacing fossil fuels if we could safely teleport nuclear waste to a sealed cavern on the moon. It's a relatively small payload (compared to transporting humans and goods) and you don't really care if an imperfect teleporting process only allows you to squeeze it through as a stream of molecular toothpaste.
