Awesome! I need one of those to keep my flying car cool.

Yeah, the Coanda would be a huge hit on Halloween.  Or really, any time of year!

Now what we have to ask ourselves is how, exactly, does Santa get up the chimney...

Very interesting... my only fear is the gyroscopic effect of spinning so much mass as such a high RPM. the bracing between each "disc" whould have to be extremely rigid!

John, Thats why I need graphene!

Forgot to add this to my last reply-

Graphene.. Standby... googling now ;-)

Graphene is the current holly grail of the material engineering nerd-dom

I've made lots of investigation last year on Tesla turbine design. The problem is an absence of scientific study on component placement (layer thickness, cross-layer gap, hole distance etc.). If brushless motors are known to reach 96% efficiency, TMs are (were) reported to reach 50%.

John,

I found some references to research by Glenn A. Barlis, including a formula for calculating the disk gap.

Does this seem legit to you? I'm still digging, lot's of learning curve left for me.
