If you have air moving at 10-20 meters/second through a very small (8mm3 volume) metal box open on both ends and you want to increase its temperature by around 1.3 times as it passes through the box, what is the most efficient way to do it taking into account the heat lost to the box, surroundings etc.?
I am guessing burning fuel as a wire won't be able to heat the air fast enough. Or are there other better ways?
