He did mention that a few small pumps were needed. I think he understated that portion of the process. The largest use of electricity in any treatment plant is pumping, if the effluent needs to be pumped twice that is significant. I would like to see more specifics as to the process and energy consumption of additional pumping. I am sure the H produced will more than offset any pumping but to dismiss it as insignificant, I am not sure. In general I think he did a good job, but let’s not forget this is a very small company with an idea that is probably worth more than anything else.
