My friends and I are having a nearly friendly debate about the effects of superhydrophobic coatings on various items, and we've decided to look here for more input.
I'm not affiliated with them in any way, haven't bought the product, but here is a video of one of these products. It was viral several months ago.
Just for fun, one of us is a social worker, one is an electrical engineer, and one is a chemical engineer.
Basically, our debate asks these questions:
1. What would happen to an extremely buoyant item with this coating, assuming that friction wouldn't just peel it off under load. Like, say a boat bottom, or a propeller. Improve speed and performance, decrease it, or no change?
2. What would happen to a perfectly neutrally buoyant item? Would it float HIGHER , would it sink, or would it remain neutral?
3. What would happen it applied to a swimmer? Would he have an easier or harder time in the water?
