Yes Jones,An open pond with a "foam blanket" to cover the CO2 works. Interesting that many small towns have waste water treating plants that are nothing more than a series of ponds located in steps where the first pond gravity flows into the next lowest earthen pond and so on. These "lagoon" systems could provide an ideal site for green machines. Task...find a better way of producing huge quanities of CO2 ... is there a way?
