12 Pieces Of Sci-Fi Tech That We Wish Were Real

As modern, forward thinking sort of folk, most people have definitely spotted the potential in 3D printing technology to make all of your nerdy dreams come true.

Already, we are able to "print" certain items and even food so the days when you can write a bit of computer code that will result in the creation of a delicious lasagne are probably not all that far off.

The obvious problem with 3D printers at the moment that prevent them from being true sci-fi replicators is this little caveat of needing the raw materials. By the time you've gone out and bought the 3D printable constituent parts of a lasagne, you may as well have made the damn thing from scratch anyway.

Nanotechnology could be the key here. If we were able to develop a 3D printer that could analyse an object on a molecular level, and then reproduce an exact copy one molecule at a time, we would be one step closer to the replicator of our dreams.

Of course the "raw ingredients" would still be a requirement, unfortunately the laws of physics dictate that you can't create something out of nothing. 

But, when we're working at a molecular level, these raw ingredients would be less "dehydrated cheese sauce" and more "a few base elements that make up everything in the universe" that can be put together in countless ways to produce literally anything.

This is probably a long way off. For now, you're better off just making your own lasagne.
