User482 said:Believe it or not, there was a Life Cycle Assessment done on this very issue, but I'm afraid I can't find the link. I do remember that it concluded that hot air dryers were better in terms of the total energy consumed. What the report didn't say though was that hot air dryers don't actually work, leaving you to finish drying your hands on your trousers.
That said the new Dyson ones are brilliant.
I am completely in agreement - the dyson ones are excellent. An innovative solution to a simple problem.
