I think this idea could disrupt the powered snowboard industry.
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).
But then I would have to know what crap I needed in advance, and go to the hardware store. I like getting to be extra lazy, and 3D printing facilitates that nicely. The end result also usually functions well and looks great.
I personally wouldn't have designed that EDF mount the way it was designed, but it works and I can't argue with the totally cool end result.
On a side note I'm super glad the author of this blog post used LiPo fire bags. I thought the hype about LiPos as bombs was overblown until one in my homemade electric bike caught fire on the charger once. I was very lucky that I always kept the bike outdoors on my porch, but never again! Always on concrete, in a bag from now on.
Still, I would expect the massive heat output of a gas turbine to be another danger as well. You are, after all, spitting extremely hot gases out the back, which could pose a great danger to anyone behind and might also melt a large amount of snow. Probably depends greatly on the method of mounting it though...
