500L CO2 per day, to make 2kwh of electricity (per day) That's approximately as much CO2 as a person breathes out in a day (https://en.wikipedia.org/wiki/Carbon_dioxide#Human_physiology https://en.wikipedia.org/wiki/Carbon_dioxide#Human_physiolog... says about 1 kg, which works out to about 560L CO2 http://www.umsl.edu/~biofuels/Energy%20Meter%20labs/How%20much%20volume%20does%20a%20kg%20of%20CO2%20occupy.pdf http://www.umsl.edu/~biofuels/Energy%20Meter%20labs/How%20mu...) So yes, it provides a little bit of power, and no, it isn't likely to scale up to planet-wide CO2 reductions - one per person on the planet just to cover the CO2 we breathe?
