What invention do you want to see most in the future?

Science Week are giving away Wii's. All I have to do is answer one simple question, what invention do you want to see most in the future?
Simple, personal rocket packs. Ever since I was, oh I don't know, very young, I wanted to be superman. This, for me was the perfect career. Then my careers guidance teacher told me that it wasn't an option. I hadn't got enough points in the Leaving Cert to get into a course on originating from Krypton.
Well I was shattered I can tell you. My dreams of flight, invulnerability to bullets and of course the ever useful xray vision were gone. Well science has answered some of these, and they just need a decent rocket pack to get me going. I'll provide the red cape, and I have some Simpsons boxers to wear outside my jeans and all.
Invunerability to bullets costs a mere $50 on ebay, check it out here.
Xray vision was sorted, once the scientists realised that looking into a girls locker room we didn't want to see their bone structure. We just wanted to see through the wall, so they invented the Backscatter xray.
But rocket packs. Well they're big and cumbersome and not very cheap, like the Bell Rocket Belt. What I want is something smaller and easier to use. Remember the Rocketeer. Now there's a rocket pack that would look good underneath a red cape. Flying through the air, checking out Lois Lane's underwear, now what better use for science could there be?
