"As these nano-scale "fuses" burn, they drive an electrical current along their length at staggering speeds. "

Don't all electric currents travel at the same speed through any conductive medium?

"Don't all electric currents travel at the same speed through any conductive medium?"

It's very complicated, but the short answer is no.Charges flow faster in a thin wire than in a thick one.

One of my son's university friends landed a plum job when he graduated, three years ago. He was employed by a Japanese nano-technology company that's developing nano satellites. Hundreds of thousands of these things would be sent up to form orbiting clouds that could be shaped by ground controllers to provide high-quality communications all over the world.

At least, that's the theory - I'm told there's a long way to go
