horrible greenhouse gas
Well, yes... But I wouldn't worry about it in this context because (surely) the CO2 that gets frozen is extracted from the air. Or am I wrong about this -- do they make it from something? As to displacement of oxygen as the melting CO2 displaces air in the cabin: I'd be interested in knowing about that because dry ice seems to be just the thing for keeping stuff cool. A friend had some last for (could this really be true?) nearly a week in his coolbox on his last cruise. I must confess to producing considerable CO2 myself every day, too. Giles Morris
