New NRG Source? Yeast?

I looked at my glass carboy today, fermenting vigorously an APA. I wonder... thats got to be alot of energy produced by the CO2 coming out of the airlock in commercial setups, can't they harness energy and turn it into electricity to run some (maybe all) of their brewery?

it's energy. but not that much.
Some German breweries harvest the CO2 from primary but I think it's so they can force carbonate while getting around the Rheinhesgebot.
The best ways to re use energy that I've seen in breweries are brewing with re claimed water and using the steam from mashing to heat another mash/ or the cooking oven in the accompanying brewpub
