Look what they did. Scientists took the concept from this desert beetle, which is able to collect water from the air in deserts where it lives, and made nanotube forests that mimic this. The material is, at this time, in the lab stage, but, once we can produce them cheaply and in mass, we could have perpetual water containers that extract drinkable water from the air.
Its really amazing. Quantum computers and quantum processors, able to compute with quantum subatomic particles, and manipulate subatomic particles directly, as well as replicators able to make any stable three dimensional pattern of molecules/atoms.
