Never ending ski slope

post #1 of 16
Thread Starter 
Check this out. It's really a little too crazy for me to comment on, so I'll leave that to everyone else.

I think I'd rather ski a bunny hill than that thing.

Seems perfectly logical to me!

And I think that says it all.

Ott can do his endless wedeln down an endless slope.

What's the trouble with these people? Like, just get on the bus and go to one of your local ski mountains after work... What? You live more than an hour from a ski hill??!! Then move... DUH!!!

That may be the future, but this is today. Ski/Board during the summer, develop & refine technique.

I use the ski deck last fall and it helped me prepare for the season.

A never-ending left turn, yay.

What happens when you get dizzy?

JR, I'm not sure what your geography is like, but the nearest ski area to Llanberis, Wales is either 428 miles to Aviemore, Scotland (over 8 hours drive time) or Chamonix, France, which is around 14 hours drive)

I wouldn't have thought so. The idea is the hill rotates, so you can always be facing straight down the fall line (tangential to the rotation of the hill). If you go slower than the hill, then you'll have to turn right (and eventually you'll be at the top! If you go faster, then you will have to turn left, but if you stay at the same speed as the hill, then you can ski side to side, or whatever.

This idea of a rotating angled turntable was, I believe, patented many moons ago.
I remember seeing a promotional document for Ski Trac over 6 years ago.
The idea is fantastic if it can work. My biggest caveat would not be its 'skiability', because that should be fine. And I think Fox Hat is right about the left turn tendency, if you get my drift.
The greater problem is someone falling below you. That skier then 'sticks' to the rotating slope, rising rapidly towards you. How do you avoid them? Who is responsible for the inevitable collision? Surely not the skier above, as with current ski safety codes!

Worms, can of, being opened.

What happens if you are a beginner and cannot ski faster than the hill? Does it drag you to the top and then crush you? That's pretty good motivation to learn quicker...

But it's one sure way to stop boarders from sitting in the middle of the hill!

It's actually beginners who are likely to gain most benefit from this kind of thing, in my experience.
'Moving carpet' type ski slopes are highly effective in teaching people the rudiments of straight running, plough, plough turns etc.
The problems arise when you go for more advanced technique. Because you're not moving down the slope, but are in a static position, you get none of the G-force that helps set edges and get a real feel for turning skis.
On the other hand, the amount of stamina you need to ski continuously for a few minutes on something like this is significant.
Your thighs really start to burn.
Any hamster regularly working out on a wheel will tell you the same thing.

Not true. You are not static, you are moving side to side, so there will still be plenty of acceleration forces acting on you, and you will still be able to practice getting your skis up on edge, etc..

The reason is that even if you are not going downhill, you are still moving side to side in something approximating sinusoidal motion, and the only possible way for this to happen is if the snow is pushing on your skis with the appropriate sideways force (which is exactly equal to your sideways acceleration). Think of yourself as a mass moving side to side on a spring.

Now, in spite of my statement above, I have to agree with your general comment that there will be differences between between skiing on a tilted turntable and real skiing, and that these will be somewhat misleading to someone aspiring to advanced skiing.

In particular, in real skiing, the center of your next turn is always downhill of you. In skiing on a turntable, the center of your next turn (and next, and next ...) is always at nearly the same "altitude" as you are on the turntable. What this means is that the various body and ski angles involved will be somewhat different between the two cases.

Another difference between skiing on one of these devices and real skiing is that for financial and safety reasons, most of the time, they probably would have to run the turntable at speeds appropriate to lower level skiers, and these speeds won't let higher level skiers feel the forces they would experience in the real world. OTOH, I'm sure they could schedule 78 RPM sessions for the really good skiers - grin.

What I would say is that skiing on one of these contraptions would certainly help a lower level skier prepare for higher level skiing, but they would still need time on a real mountain to dial in their technique.
