Nanotechnology: Beyond Your Wildest Dreams
Nanotechnology is the science of moving individual atoms around and putting them precisely where we want.
Since everything is composed of atoms, by doing this we can, in theory, construct anything we want.
For example, by moving around the atoms in a piece of coal, we could create a diamond.
Currently, nanotechnology is still quite crude. Scientists can alter the properties of things like plastics or cloth to make them harder or softer or more durable, but they can’t build something new from a collection of atoms.
Why? Well, because things are made up of billions of atoms and it takes too long to move them around.
So, the next big step in nanotechnology will be building machines that can do this automatically.
Once we have these we should be able to make almost anything with no waste and no pollution, at very little cost.
Scientists think that the first “Universal Assembler” might be built in around 15 years.
