I just got this data from COMET-ME 
It shows the power output and the rpm speed of a 4200 turbine based on my recipe, except that Noam at COMET-ME uses 20 magnets instead of 16 in the alternator (photos here).
Real time data for some COMET-ME systems is visible via this link here

I recieved the book yesterday and when it arrived I thought ‘this isn’t worth £12’.
But how wrong I was once I’d opened the envelope and settled down to read the contents with a cup of coffee. 3 hours later the coffee was stone cold and I was still reading the book.
Loads of info to be getting on with.
I’ll email Hugh when my terbine is up and running with some pics.
Thanks a lot.
Michael.
Thanks Hugh. I like how this scatter shows power and speed control.

How does this power curve rate with the model with 16 magnets?
