Weekend Open Forum: What sci-fi tech would you like to see become reality?

I hope all the technology in star trek become reality, so human will be united just like in star trek.
 
One thing from cartoons:

1) Dragonball Capsule Corp. Capsules - these devices use technology to store the molecules of objects in a small capsule for easy transportation, and are about the size of a small 16G CO2 canister/cartridge. The objects are stored in a gaseous state inside the capsule. When triggered, the capsule shall be tossed some distance away from the user, then the capsule releases the molecules of the item in a sudden explosion-like gas cloud. Presumably nano-machinery reassembles the objects. After a few short seconds the stored item becomes self aligned and fully functioning. Items can range from machinery such as a car or airplane, to fully functioning houses complete with plumbing and electricity! Items can be returned to their capsule state by pressing a button on the item allowing it to transition back to a gas. Which is somehow vacuumed back into the small capsule.

Also, a nod toward the Portal Gun or other teleportation-like devices.
 
Everyone almost got all expect forgot one most important thing is force field which it will protect you from tiny meteor go through ship hull. Also it can protect us from tornado or hurricane.

OK, but you do realize that those little capsules have to weigh as much as the full sized version, er right?
