I agree with everyone that this is not "real" skiing, no cold weather, no snow and no scenary... However, it is a solution for the people who have never skied and cannot afford to the traveling to get into action. Perhaps they will be able to get hooked and become one of us. Also for those who wish to practice their skiing skills when there is no snow, especially for those who wish to practice park skills or mogul skills. Not everyone can fly over to Chile in the summer. I think it is a positive move in the skiing industry.
Yes you might get carpet burns, but if you have enough protections, like different paddings, the burns can be minimal. Yes, its going to be hot, but playing basketball, baseball, football..... all will generate the same heat level, perhaps more so than skiing.
Here is an indication of why this will be successful. Sam, who is the maker of rolling carpet skiing machine, endless slope, is running a profitable business teaching skiing in San Francisco and Sacramento. And you will ask, why ppl in Sacramento will ever wish to "ski" on a machine? The answer is that serves the 98% of the population who have never skied....http://www.endlesslope.com
