Does running a fan clockwise in winter actually do anything?

[George Lucas]

Did you know that there’s a switch on ceiling fans that reverses the fan from anticlockwise to clockwise. When running the fan at a low speed, this is supposed to circulate the air and make the cold parts of the room (i.e. the bottom) warmer.

Does this actually work though? Or is it a marketing gimmick to get people to install fans in winter?

You're not supposed to do that, it makes the electricity go bad.

The fan distributes the air temperature more evenly throughout the room.

That's for usage in Australia. Otherwise it doesn't do anything.
