Fans are great at circulating air around a room or house in the summertime. So why is it that they only point in one direction? The double room circulator is a double-headed fan, one that can be pointed in two directions at once for maximum circulation.
It's a pretty genius idea, really. Having the fans pointing in two directions will speed up the circulating air, clearing out the hot air and cooling everyone down. Why would you want a stupid single fan after seeing this?
