And more recently, heat pump dryers, which can dry basically as fast as standard electric dryers, while not requiring a vent, and using much less energy. You get double benefit form the heat pump, as the hot side heats the air in the dryer more efficiently than a (resistance-based) electric heater, and the cold side chills the moist air, extracting the water to be drained.
