Seems like using thrust is going to be a limitation here. What about some kind of belt that contacts the ground when activated?

[erobbins]

you could also add a seat for when you get tired of standing, and maybe a steering mechanism as well, and a cowling to cut down on wind resistance.

I think this idea could disrupt the powered snowboard industry.

I like the idea. If you have a surface to react against, why not use it? It doesn't change the functionality, so it isn't just becoming a snowmobile as others claim, you just have to set it up so it maintains ability to slide.

I think a pair of small tracks on the back with some kind of speed sensors to make it coast without drag is ideal (think bike coasting system with drag compensation).

He would either need to cut a space for the track into the board (there goes an expensive board if the results are poor) or put two tracks on either side of the board like training wheels. I don't think either makes sense as the first is too destructive and risky and the second will severely limit turning even more and most likely add unneeded weight.

Or hang it off the back perhaps

[branchan]

Then he would just be making a snowmobile.

[grimmdude]

Similar, but you'd be standing on it and there's no steerable front. Much different if you ask me.

Almost a hybrid snowmobile/hovercraft
