What's a cool futuristic invention?

Question

I'm looking for good ideas of a good futuristic invention please help

Answer 1

I'm holding out for a nuclear fusion reactor - unlimited, pollution-free power.

I expect we'll see it happen in the next 20 yrs or so.

Answer 2

I was thinking of a lo tech fire tool for going right through a concrete wall(as in a warehouse fire) and a 360 degree sprinkler head on the end.You put a hydraulic ram up on the tall ladder with a thick wall steel tube that can extend and "ram" through a wall and then spray water all around behind the wall instead of just from 1 direction.

I call it a "fireball" with the "no" symbol in front.

Answer 3

A computer inventory of everything in your home, so that if you can't find anything, you can type its name in on a screen and it'll find it for you using some kind of scanner.

Answer 4

Food memories.  You go to the grocery store pick out a frozen dinner box that has a delivery system like a pill or a type of human interface memory card.  The memories of a great meal complete with the "fixings" the tastes sensations etc.  

All the folks that cannot afford a great meal can buy the video memories while eating Mac & Cheese a coke and fries.  On the upside you avoid clean up and over-cooked food!
