Log scale: 10^2 = 100 = 2 orders of magnitude. Still a bit nonsensical to say 30,000 times smaller though. Most of us can't really get a handle on what that means (although 100 nm might also be hard to grasp for some).
This is genius! Think about possible extensions of this. We could have nanomanchines even going through the body killing disease and not have to worry about powering them.
