  I would invent travelling at the speed of light. Then we can visit within a few years other stars which have other planets floating around them, we can go to Mars in only 733 seconds – which would be super cool.

  I would like to invent something that vould purify water in just a few seconds. So many people die becsuse of bad water that if we had something available to all and really simple to use we could improve the lives of millions of people.

  I would invent a teleporter, which would mean we could put satellites in space without any tough launches (spacecraft are all designed structurally to survive the launch as it is such a rough ride, lots of vibrations, noise and shocks) so if we didn’t have to deal with a launch we could make spacecraft faster, easier and cheaper.

  I would invent a machine that produces free clean energy at an unlimited capacity at our time frame. It would open up everything for us. Clean water, food for everyone and possibly inter galactic travel!
