O.o wow. Your arguments are presented poorly. Maybe you were hasty.

1. Your first point is flawed. In engineering the transfer function you describe (O/I) does not apply here. The number of H_2 produced compared to the rate of photon absorbed of energy x would be a legitimate example. However using the mechanism itself is wrong here. Another good example would be to have a differential equation for the rate of hydrogen generation vs light and surface area or incident angle. Great in a spec document, but useless to investors.

2. Economies of scale very much matter. The clients that would be designing systems around these PEC particles would make pricing models around the intended system sizes and enter negotiations armed with them. A large amount of the costs of such a system has nothing to do with the part HYSR would contribute.

3. 1.23V is the amount of potential needed to split water. The 1.5 to 1.8 V range is common amoung electrolysis systems to overcome losses. Its a good engineering practice to have overhead in both performance and safety systems. In performance systems it can mask some fabrication imperfections or allow for degradation over time without sending a client into a hissy fit. And in safety systems... well.. naturally caution is valued.
