Very cool - i cant wait to build a machine with one - but it still spins, "fanless" made me initially assume no moving parts.
When I was reading that a couple days ago I was thinking, wouldn't it be neat if they could use the heat to make it spin instead of using an electric motor? It may not be much more efficient but it would be cool to use the waste heat that way.
