I saw this showing up in my social media

"Dyson Airblades 'spread germs 1,300 times more than paper towels'"

http://www.telegraph.co.uk/news/2016/04/13/dyson-airblades-spread-germs-1300-times-more-than-paper-towels/

This is so misleading as to be false.  The actual study is very positive about the use of the Dyson hand dryers.

Quote
The ultra-rapid Airblade™ hand dryer was shown to be superior to the warm air dryers for reducing bacterial transfer. The lack of paper waste, coupled with its short, 10 s drying time and use of HEPA-filtered air should encourage greater compliance with hand drying and thus help reduce the spread of infectious agents by the hand-borne route.

The paper towels were found to work better in some ways but the benefits of the Air Blade, in the opinions of the authors, outweighed its detractions.

My only problem with them is that they don't dry my hands well.
common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools.

You gotta use your pants to dry your hands.
