A kind of analytical way to come at this is to start with the sources of danger, and then think about ways to minimize that danger. Some obvious ones:
- Avalanches. Definitely of interest, as the discussion above indicates. For one thing, they don't (necessarily) just hurt people, they kill them. Some ways to go at it:
* Improving rescue (again, see above). Work has been done here, obviously, but maybe there's a new idea.
* Assisting skiers to identify and avoid risk. Some stuff here, but not so much.
* Assisting ski areas in identifying and reducing risk (aka "avalanche control")
- Non-avalanche snow immersion (hey, it even has it's own acronym: NARSID). Tree wells, for example. Also sometimes deadly, so could be exciting, I suppose.
- Injury to legs as a result of having a big lever arm attached to your foot. It's safe to say that this one has had a lot of work done on it. Might want to think about electronic bindings, or ideas specifically aimed at protecting knee ligaments.
- Collisions: skier-to-skier, skier-to-boarder, boarder-to-boarder. This one seems to be on the rise: certainly awareness of it as a danger seems to be. A big advantage of working on this danger is that I'm not aware that anyone has (at least not much). There may be some clever ideas to be had (as well as some controversial, some stupid, but at least interesting for a project).
- Lift loading and unloading. Sounds dumb, but this is where ski areas actually seem to have the greatest exposure. If you get credit for making an argument for commercial viability, that could improve your project.
