Not a flame thrower, but it is a vehicle which clears snow by melting it.

Its quite unintuitive how hard it is to melt snow.
From the energy perspective, you need a certain amount to increase the temperature of the snow form initial temperature to over 0°C, and another amount to overcome the latent heat (heat of transformation) from solid ice to liquid water.
The latter, the heat of transformation from solid to liquid, is quite large and has been used for making ice cream whitout a refrigerator: Melting ice cubes in a large bowl with the help of salt was used as a cooling agent to freeze the ingedients contained in a smaller bowl placed inside the larger one.
Well it’s not gonna be very effective at blowing snow.
Also: They make videos now? 😮
that channel posted its first video more than a year ago and videos from it have been posted to this community before
Someone post the comic about people learning something for the first time.
