well my variation on the design is going to have a bell or cone above the hydrogen electrode ---with a small diameter pipe going up & out of the area (house ,greenhouse,building) that way the hydrogen gets vented away from the fish as much as possible ----it will be piped to the generator to help power it for electricity returns ---so basically the system will almost power itself ----I was also trying to design a way to run the generator on woodgas & hydrogen combo ---that way the only fuel would be wood chips from a local treeservice & the extra explosive power being fed into the generator would come from the hydrogen ---since woodgas has like half the punch of gasoline --im hoping the hydrogen will get the power back up there closer to a gasoline powered generators capability ????
