Could the use of artificial muscles made of carbon nanotubes be a viable solution to nanomachinery? The main problem that I hear when talking about "nanomachines" is the fact that the complexity of some objects like a motor or even gears and mechanisms like this just don't work in a microscopic environment in the same way that it would on a macro scale. If all these artificial muscles need is electricity to generate a force, then how viable would this be on nanotechnology? It seems like it solves the problem with reduced complexity and being potentially applicable on a small scale because of the size of carbon nanotubes. Don't know much about the topic so any input would be good.
