The fanless spinning heatsink: more efficient, and immune to dust and detritus

"Fanless" in that it is a fan itself.

It is fanless in an important sense. The job of a fan is to move the air, for which small fans are inefficient. Then, the relative motion of the air vs the heatsink allows cooling. But in this device, as the report says, the relative motion of the air vs the fins is obtained directly - and much more efficiently. The fact that the device also serves to move the air - as a fan - is irrelevant.

If the device didn't also move air away, wouldn't the air it was standing in be much higher, reducing its efficiency?

Edit: Of course, in a computer case there would be other fans which would keep replacing the air. Silly me!

Semantics.

Semantics matter. Would you rather argue about syntax?
