Turbine powered rotary tool (Video)

Here's a robot video that I found interesting:

A 3-d printed 2-stage axial turbine powered by a standard vacuum cleaner. It spins at 60,000 rpm, sounds like a 747 taking off, and sucks up its own dust! A production version could be a very useful tool. See http://www.thingiverse.com/thing:76369
