from a frequency analysis of Romero's video when running without battery,

the spectrum shows a broad peak (of several hundred Hz width) centred on 188Hz
(over a 1 second snapshot)

however, if that was the rotor audio component then that would make it around 11000 rpm

i understand Ron to say that acrylic wouldn't cope much above 1000 without some re-inforcement

it should be noted that this rotor was apparently constructed from 3 or 4 layers glued together

iirc the run-down period is approx 100s

hope this helps

Come on, nul, dont like you´ll kill somebody, 11.000 rpm ... have you any idea what it means
It is not so hard to understand that Romeros rotor spins somewhere between 1250 ...1350 rpm,
cheers,

i would recomand to use as much as possible  ( better sayd only ) all bolts and screws and axel   - . in plastic  or INOX = Stainless steel ,  to avoid magnetic interaction with the rotor.

Plastic = yes
Stainless & aluminum or any other CONDUCTOR = NO

Just take big chunk of either and bring close to rotor. Watch rpm / amp draw

Okay, here is the last movie,
where RomeroUK suspended his generator in one hand and
ran through his house.
