Very great advice, I don't want to kill people but help them after all. But if I remember correctly the cellar was about 10m².
Did you mean combining blades of fans?
Also have you done this already once or more? And if so, can you share pictures?
I have done something similar but not for living conditions. Rather for a room containing fermenters. I don't have pictures to share though, since I no longer work at that place.
If you don't have the knowledge to put together a make-shift fan, then I'd suggest to go out and buy something like the one that another commenter suggested. I only suggested something like that because it would cut down your costs significantly. If you have no experience in doing something like that though, it'd be a lot safer to buy something ready.
You need a carbon monoxide detector not carbon dioxide. I don't know if that's just a mistake but monoxide is the dangerous one that's more dense than oxygen and puts people to sleep.
I assumed his plan was to have a carbon dioxide sensor that would activate the fan. Humans don't breathe out carbon monoxide and it doesn't float in the atmosphere in large quantities, so while life-saving by itself, a CO sensor would be useless for activating the fan regularly. For purposes of ventilation, a rise in carbon dioxide concentration means a reduction in oxygen.
Carbon dioxide is heavier than carbon monoxide by the way.

Yeah combining blades into one.
