New hand driers at client co

[Churchill]

Actually dries your tongue very well, from experience. Could be good for doggies.

Have you seen the crap that lives in the bottom of those things?

[Spacecadet]

Yeah, they are pretty effective, it must be cheaper to blow air than to heat it too. Might be improved with a buzzer that goes off if you touch the sides, or an electric shock.

They also heat the air

I am curious as to how the lable on the front of them proclaims that they are the "Most Hygenic" hand driers. Given that there is more chance of touching the sides of the drier and the way water drips of your hands into the bottom of the device I would have thought that they were less hygenic than old style hand driers

....but more hygienic than the dirty old stripey towel hanging from the wooden roller.

Like anything Dyson they will be on the rubbish tip in a few months.

I had one of their first bagless vacuum cleaners. Worked ok but nowhere near as good as my Henry which cost less than half the price of the Dyson.

A faster dry time and no energy-hungry heating element means the Dyson Airblade™ hand dryer costs up to 80% less to run than warm air hand dryers and up to 97% less than paper towels.

They spread bacteria all over the place and if you publish a paper with your findings through evidence Dyson's lawyers go after you even if it is the truth.

Experience tells me otherwise!
Perhaps there is a different mechanism heating the air - they definitely "warm up" during longer use

perhaps it has something to do with the. Velocity at which the air is expelled?

Website say is uses 1,600W, so if it's say 60% efficient, leaves a lot (maybe 1kW) of energy, perhaps KE of the air.

Alternatively website says the air is travelling at 400mph, or 178 m/s, which is more than the average speed difference of air molecules of 20 degrees C versus 100 degrees C. So the air could feel warm, alternatively it might well heat the unit up as it passes obstructions. Either way, that 1.6kW is ending up someplace.
