Using a Dyson hand dryer is like setting off a viral bomb in a bathroom

Yep, but I found over time that I tense my arm muscles before going in and now can keep them fairly steady in the middle without touching. Call it a learning curve I guess.

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.

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.

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.

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).
