You don't have to reveal exactly how it works - that might be your core IP that needs protecting later on.

Just treat it like a black box at this stage and tell us what it can do, why that's useful, who needs it, how much it'll cost them, how much profit you'll make. That's what business people care about - not the details of the technology.

RNG's today operate on thermal fluctuations and alternatively current "shot noise." These methods are in principle sources of quantum entropy.  However, they work on integrated circuits so nobody knows whats really going on inside of it.  One can perhaps test the legitimacy of the outputs, but I do not like the idea of ICs used in open source technology since they can always be backdoored - one must trust the IC manufacturer to use the IC.

This is different in that anyone with an electronics hobby can scrutinize it; these electronics presented are completely analog. One can also feel free to exchange the (sodium chlorate?) sample with their own if they believe I have doctored mine.  It's simple physics, rather than black-box electronics.
