  A time machine would be pretty sweet to have (especially if it’s a DeLorian), but for the good of mankind, an invention of a super food to feed everyone, or a way of providing free energy to everyone without the need to damage the planet.

  If I’m not allowed a Tardis, then I’d go for instant travel. We could visit every corner of the universe in no time and see if there are advanced aliens who could help us out.
