Yes, I was thinking it might be a static vs. kinetic friction effect in the mountings, too.

comment Can a car steer on a frictionless surface?

comment Most efficient way to cool a two story house with two fans?
Yes, but you have gravity to fight against trying to get the cold air upstairs, no?

@BMS: lower cooling time → higher efficiency
