All the cool bathrooms now use one of the dyson airblade drying systems for hands. But how cool would it be to have such a high powered dryer in the darkroom. Rinse your hands after touching chemistry and be dry in seconds. Place a wet print under there and you could have a quick dry down for review. Just sayin...
I don't know. Those dryers work well on surface water and may be great for RC paper. What if you tried to dry a towel (or other item with water interspersed between fibers; fiber print). For years I dried my fiber-based test strips in a microwave oven. Now I use a conventional 'photographic paper dryer' for test prints.
We have one around the corner from the old darkroom and I used it a few times to quickly dry off Paterson reels. Much better is the Xlerator hand dryer that is in another building, much higher velocity than the Dyson but much lower coolth factor. http://www.exceldryer.com/
Good for drydown check I imagine, but those things really blast and I wouldn't want to end up with wrinkled emulsion if I tried it on a finished print.
Also, of course, they cost £600-£800 to an end user. That'd buy a lot of other photoey things. Or pay the rent for a few weeks. Or put some food on the table.
