Hello Barry and everybody,

there is a company called Mercedes Benz which still puts the engine the old way 
behind the radiator and uses a belt driven fan. But this fan has an automatic  
clutch which disconnects the fan at the times it is not needed. You see there 
are really many brainstorming heads having a lot of ideas. They all just try to 
find a way to take the load of the fan off even if it would be much easyer and 
cheaper to keep a constant linked fan.
