Thanks, that's a relief, shows I didn't screw up the arithmetic!
No but you mixed up a . and , when you applied Betzs' Law.;)

Thats the one !, cheers Stan.

You can even see that Archimedes screw turbine a couple of times in the video, I won't be investing.

I've seen mine up close and its the real deal with a 100m rotor. (pic actually taken by me on the open day)

Currently chucking out near 2MW as I type this with my share over 2kW. :twisted:
