What new invention do you want to see in the next 10 years?

Question

OK, We have ipod, computer, internet, iphone, etc. So what else do you want to invent? Be realistic, something like time machine is almost impossible.

Answer 1

Answer this question correctly and you become a billionaire.  That is, if we knew what we would want to have in ten years, we would probably not be wasting our time on Yahoo, but rather making that idea become a reality.

Answer 2

A vehicle designed to run on water.  One already exists, but its a prototype.  Id like to see it put into production, but that would damper the issue with running out of clean drinkable water.
