- olau 6y agoNo, although if it's cold outside, you might get a sea breeze effect. But most of the time (say > 80% IIRC) in Northern Europe there is at least some wind, and having a large cross sectional area is just incredibly efficient. You can try the experiment yourself. The main problem is that it is a manual process requiring discipline, and if you don't do it, your brain suffers due to elevated CO2 levels.
