Like the paper-or-plastic debate, how to dry your hands in a public bathroom seems to be easy to discuss, but not terribly simple to do anything about. Many people dislike air dryers because they are slow, noisy and power-sucking. On the other hand, paper towels are an ongoing source of waste and tree killing. Frankly it's all too confusing. Will technology come to our rescue?
Dyson, makers of the noted vacuum cleaners, have a solution that may win a few more converts over to paperless, and provide a great energy savings compared to conventional air dryers.
The Dyson Airblade is 80% more efficient than conventional air dryers, using a fast (400 mph), thin (0.3mm, the width of an eyelash) sheet of air to dry hands in about 12 seconds (which, for me at least, equals or exceeds paper-towel speed). Dyson claims a 98% cost savings over paper towels. Since the air does not need to be heated with the Airblade, it does not need warm-up time, and will dry the hands more quickly. Rather than forcing evaporation (as a conventional dryer does), the Airblade uses high speed air to wipe water away. Dyson also claims to be the first and only hand dryer certified by NSF International.
