Today, I was in Stanstead Airport after a workshop at Hinxton. One thing which caught my eye was their heavy-duty, hot-air, hand-dryers. Or caught my ear, as there were really pretty loud. They work in much the normal way — they blow hot air — but much more powerfully than normal; you could see the air stretching the skin over the bones.
The main reason thing that I noticed was the stickers on them saying that they used 80% less energy than normal dryers. Slightly ironic really that an airport, which has 100 ton hair dryer landing every five minutes, should worry about energy efficiency.
