An Organ of Fire and Ice

An organ that I built for my senior project at Union College. The thermoacoustic instrument produces sound because of the temperature difference between a propane flame and liquid nitrogen.

cool concept, but, not really that good of an instrument.

@treyweeeee Think of it more of a proof of concept. Thermoacoustics is much more useful in the field of refrigeration.

my god that needs tuning.

@plasmagrape Funny you should mention it. The pitch of any organ pipe is dependent on its length and the speed of sound. The lengths were cut correctly, but the liquid nitrogen cooled the air enough to change the speed of sound and thus the pitch.

This is nice. Our organs should meet.

Wow, very nice one you've made. The notes on mine are actually produced by the flames, but you've got the tuning and theatrics down much better.

hehe you are funny man

You need a way of adjusting the tuning! We have the same problem with our hydraulophones: if we calculate the length and cut to length, it ends up requiring some fine-tuning by ear, due to differences in the mathematics and reality.

Stuff like this interests me so much, id like 2 do things and projects such as this when im older. i like 2 think i have a good mind and think of things in a different way then others. and also get mad at stupid ppl of not knowing thigns that can be easily thought out though events.

sounds like crap!

[Captaingoldstubble]

Thumbs up if you're an engineer and love shit like this!

O.O that is sooooo amazing I have never seen any thing like that before!! O
