This is an interesting idea and probably would be useful but would only address people in single-family dwellings that don't share driers. I'm guessing that there is a reasonable use of clothes driers in commercial settings (laundry services) and shared driers in multi-family/large residential complexes (although many modern upscale projects have in-unit driers) where driers are shared. Probably the best solution is a cultural shift to air drying. I was very surprised that when I was in the UK, a place not known for sunshine, many air dried their clothes, while when I lived in the desert of Eastern WA nearly everyone used a drier.
