Hi, everyone... this is my first Thread, I'm 16 years old and have an intrest in science.
Anyhow, I'll get to my subject:
Nanotechnology has advanced throughout these years, yet it is still a new technology that didn't even start to shed its light to our world. I have this idea of a spray that shoots out nano-bots which attach to each other forming a blob in the air. These bots would be light enough to stay aloft, or would have built-in engines that keep them flying. they would react with the air (O2, CO2, N,...) creating a sheild preventing objects from entering the perimiter of the blob. I know this may sound like nonsense, but it may have other uses such as cleaning poluted air and water...
please reply stating whether this is possible, if so please explain how it may be acheived.
Thanx
