With a trillion dollars could you invent a new mode of transportation?
Needs to be faster than typical commercial aviation, but just as safe.
For some reason I keep imagining firing people out of a cannon in some type of ship, with a parachute for landing.
If this isn't doable for transportation, could you use it for shipping. Say you have a famine situation, but typical aircraft won't work. Could you just put a bunch of supplies in a hollow cannon ball and launch it ?
