I'm still waiting for MIT to announce that they got this one to run. The whole package is about the size of a dime. The spool runs at 1.4 million rpm. Thrust to weight ratio is supposed to be around 100:1. As far as I know, they're still working on it.

Hello Paul
I was one week at MIT a month a go and could not get much information reg. this high speed turbine it looked like it was hibernating right now.
But I did see a proof of concept turbine with 50 % efficiency this will really be a step forward I think the best to day are Capstone with app 32-35 % .
