What happens when hydrogen meets oxygen?

[Lapin Dormant]

Silenced myself

Sorry, man, but the noise is an integral part of the 'outflow'. This is nothing like the exhaust from a piston engine. It's a very high volume of hot, fast-moving gas coming through a tuned nozzle. There are all sorts of harmonics and mechanical vibrations to deal with. A moderately sized engine (J-34, as used in drag racers) literally shakes the ground for hundreds of feet around it. The thing in Fred's picture is much smaller, but I bet it's probably at least half as noisy.

Yes I understood that point.

The noise will only cancel out at the point where the two waves interfere. Beyond that you'll still hear the noise.

Interference isn't the goal, cancellation is, then there is no more noise, but, as it is stated above, it would be diffcult, at best, I already knew that, so now, this thread seems to be getting 'hi-jacked' to this topic, so, as to discourage that, I will cease, now.
Thanks

hopefully testing it this weekend. it depends on how lazy my group members become

Good luck, Ki. Keep us updated.

hmm... before i test this i am going to ask the people something in the general physics section

if i ever become famous, my phrase that people are going to remember after i die is: it all started with a daydream

According to your theory if two speakers attached to a hi-fi are placed in front of each other, the sound should diminish near completely. But that is not what happens. The sound energy can't disappear into the thin air.

If you would like to start a new thread, the waves need be equal and Opposite each other, in waveform.

okay, definitely testing it this weekend

Ki, it appears that the stoned bunny has been banned, so perhaps this thread can stay more or less on topic now. Again, I offer my best wishes for the success of your project.

 

[Ki Man]

me and my group members are hopefully meeting on saterday and going to home depot to buy the proper supplies hopefully unless one of them can't make it. again

ty for the suppor teven if it doesn't work. we are basically researching equalibrums in a sense, but different. if i told you my full idea, youd think i was crazy probably, but it just might work so i'll just keep it secret

 

[Ki Man]

wow i haven't been here in a long time. schools keeping me busy sorry

anyways the testing of it failed. it was designed to be a loophole around themrodynamics/perpetual motion machine. well i came close, but these things can't be done on a 3 dollar budget

anyways now I'm reading up on eintsteins theories and the quest for a theory to the universe so that i can publish some papers on gravity eventually, but don't expect anything until after a few months at least for me to get anything worth done. right now its all research. and i dot have all the time in the world. I'm still in 8th grade so i have time being eaten up by english, math, history, band... this is going to take a looong time

 

[Danger]

Don't sweat it, bud. Einstein was a wee bit older than you and it took him more than a couple of weeks.

 

[Ki Man]

yep. and einstein failed algebra, dropped out of high school, got a job at the bottom of the foodchain in a patent office, then wormed his way into college, and thought up relativity.

 

[Danger]

Yeah, he was a sneaky bastard.
