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

Then he would just be making a snowmobile.

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

How would a gas turbine be safer? Much more heat, flammable fuel, so I'm curious as to the reasons.

It wouldn't, and it would suck fuel like crazy. Fans aren't optimal for low speed thrust.. turbojets even less so :) 2 fans would be much better than 1 jet.

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.

not safer, though with [bigger] gas turbine you can get something like this :

or with bigger propeller : https://www.youtube.com/watch?v=C_UtPmb3Z-o (in the San Carlos museum btw)

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.

The amazing part is the energy density and discharge rate of LIPO batteries. Also the ducted fan is impressive for its size. As a hobby project its fun to watch. As a consumer product, the noise pollution would turn the average alpine ski resort into the audio equivalent of a highway.
