The PWM scheme is basically throttling back a runaway reaction that doesn't really have any stable state between starvation and runaway but creates stability using duty factor. The PWM has to be balanced against the slower heat extraction loop so the controlled increase or reduction of any individual module (while maintaining over unity) is going to be relatively slow - I don't think any significant fast change in output power other than totally quenching the reaction is possible BUT he may be able to side step that issue by small PWM manipulations To 100 reactors at a time such that the device can respond to load variations.

I wonder if there have been actual changes or if Rossi is deliberately spreading misleading information. Cheers, S.A.
