Very cool : oD I want one to power my PSP when I get it, just for coolness factor if nothing else.

I agree with your "mirco micro turbine" terminology. Yeah, if jet engine for model airplane could be called micro turbine, this is surely mirco micro turbine.

One million rpm. I am really interested in how he's going to do with the gearbox and alternator which convert mechanical work to electricity.

I am also very curious on what thermal efficiency this kinda turbine could achieve, as we know the rule for efficiency: "the bigger the better."

So many questions in my mind, what kind of bearing will he use ? what about combustor, fuel pump ? ...

I don't know if it answers any of your questions, but there's more information about the project in this paper: http://www.asme.org/igti/resources/arti ... -38866.pdf

It answered virtually all my questions. Many thanks.

They are using the facilities in the semiconductor industry to make tiny turbines. BTW, we have many nice 8" and 12" semiconductor foundries here on this island too. I wonder how much will it cost to order a 8" wafer full of tiny turbines ? :-)

here's another pdf. about this engine that I posted a little while ago- some good pics in this one:
