Exactly. This is an extreme - and ever more prevalent - illustration of why I don't use air dryers in public restrooms. It also bothers when they says it's done to help the environment. Even if that's true (unlikely, but it saves money and generates good PR), it just makes the environment and those in it dirtier, which probably doesn't help most people.

This test was done with a hand dipped in a virus. When in real life this is only used after you wash your hands. That doesn't seem like a very accurate test IMO. Science.

I read that as suggesting that the concentration of viruses in the dipping solution was intended to produce a coating comparable to someone who hadn't washed their hands much at all. I wonder how much energy (so to speak) has been put into using a strong vacuum, either by itself or with a blower, to dry hands. Filtering that airflow wouldn't be too difficult, though obviously more expensive.

You can plant more trees. You can't un-burn the coal that spins the motor. (I wonder if there's a way of actually comparing the environmental impact, though).

The degree of dispersion should be the same, though, right? It's just that with a lower starting density you end up with a lower ending density. But the relative performance of the methods would still be valid.

My main grievance with Dyson dryers it that it's difficult keeping your hands in the little narrow gap while the jet is blasting your hands, without touching the sides. It kind of defeats the point if you end up touching the dryer.

It seems like a case of form over function.

This is the correct answer. It should be blowing all of the CLEAN that's on your hand all over the room from having just washed your hands.

Planting trees sequesters the CO2 that was emitted from the burning of the coal. Cutting trees down and turning them into paper that easily decomposes hastens the release of the previously sequestered CO2 back into the atmosphere, killing us all.

Every time you use a paper towel, you kill a puppy.
