I suppose someone might figure a way to economically scale the methane captured here.
Of course the method this person used, agitating the bottom of the pond, could have an adverse impact of the ecosystem of the pond itself. Do they rely on trace quantities of methane in some way? Will the muddy & cloudy disturbed water make survival harder, maybe killing the biomass that was generating the methane? Who knows. Well, someone might know, but I guess my point is that agitating metastable systems can have outcomes that are hard to predict.
