Comment on Building a 3D Printed Electric Jet Powered Snowboard

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

Depending on the fuel, gas turbines can be much safer. The current and voltage he's working with is fairly dangerous for close contact, where it takes a great deal of effort to ignite kerosene or diesel fuel in an open air environment.

Ah, ok. That makes more sense now.

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...

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.

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)
