Fairly good laugh *link inside*

blower really wouldn't The hair dryer wouldn't even push enough air to make any postive boost. but the blower pushes out the same temp it brings in, at least mine does, the air doesn't even enter a hotarea on the motor, the motor spins the shaft which spins the fan, working just like a turbo/supercharger would in theory and the gains from the blower would overshadow the losses from the little if any extra heat produced.

only reason the hair dryer would make hot air b/c it passes the through the warming coils and they heat the air, but when th drier is set on cool those coils turn off and so the air just comes right through.

The problem with hair dryers, leaf blowers, and electric superchargers is that they don't compress the air.
