Like you, I don't have the technical grounding to discuss this invention in anything but layman's terms, but from what I understand, Rossi plans to daisy-chain an array of his small devices together to achieve the next greater level of energy output.
Others have speculated on why he's chosen to do that, instead of scaling up the size of his reactor.
I believe the main reason he uses the small modules in series is that the reaction is easier to control and he wants to maximize safety. I read that on startup with the larger modules there is an instant where there are bursts of radiation. Rossi wants to be able to assure regulators that these devices are absolutely safe.
