I'd like someone could invent the Teleportation. And with the "travels" for free, of course :P

I think that it will be nanotechnology used in manufacturing . Amazing effects can be achieved by engineering nanoparticles; for example, researchers have already developed wool and silk that can clean themselves because their altered particles “eat” stains.

you guys maybe will move to my homeland,Mars.

There will always be small breakthroughs is technology, but I feel the most important ones will be those dealing in how we interact with electricity. I feel technologies such as smart grids, virus batteries, and super conductors will be the most important. Almost all technology requires electricity. A breakthrough in electricity would be an advancement for all technology.

there are many new technologies but all the new achievements have been possible with the web, internet is allowing the exponential growth of the world, i agree with nightmary, now with internet we have achieved the possibility to go virtually where we want and access to all informations, the next breakthrough could be the possibility to go quickly in any place of the world; in my opinion is not correct to compare internet with the sustainable technology,we can live with the "non-sustainable" technologies, there isn't a difference in terms of human development if you use sustainable tecnology
