  • Go take a chemistry class. First of all, waves in the ocean do not always spike up. With waves in the ocean if they overlap with the trough (bottom of the wave) at the crest (top of the wave) of the opposing wave it will make them level out, so even if sound waves did actually work in the way you describe, it would not give you any kind of thrust in your UFO. Second, Sound is a pressure wave! These waves will pass directly through each other, not spike and "boom".

  • wouldn't work, sound can't push it back, unless the speaker is below the ship on the ground. then you could have just used magnets.

  • I guess you could try and place to speakers facing each other in the right phase with each other so they are constructive. adn they you would have to do calculations with the air its moving and the momentum of the craft your trying to move like you do with rocket science.

  • @TheUFOeffect: I jsut remembered that would waves are longitudinal not transverse. they dont work like water waves. light waves are like water waves

  • unfortunately sound waves do not travel in a vaccuum.

  • @slymantec scalar waves do, but nobody except Tesla understood them and if I did I wouldn't admit it until I had a working prototype whizzing around and collecting space junk for my lunar junkyard.

  • Can you imagine one of these sitting on blocks in some rednecks yard blasting country western music? Gives me the shivers.

  • sound propulsion is impractical because it takes a lot of energy and it will not work in outer space

  • this wont work in space =/

  • Just a thought , Implementing some sort of echo system to combat the troughs and cancelation of peak waves. e.g once the colliding audio waves have created the propultion peak, the waves could be rebounded creating a continueum of pressure that would effectively put a peak following a peak while canceling the trough. I could probably explain clearer with a diagram which I will endeaver to do.

  • Even if the sound waves cancel, the propulsion is still there. The sound will cancel but in theory the force behind the waves still exist.

  • cool, i think sound should be able to split water very cheaply and give us hydrogen for energy as well.

  • look up the airborne ultrasound tactile display. it is an ultrasound device that focuses the sound waves to create the illusion of touching things. in short it uses sound to make a force that you can actually feel. i imagine that it would be possible to magnify this effect for use in your idea.

  • makes perfect sense!

  • would be a bit noisy wouldent it, to make all that power

  • there are ultralow/high frequencies that are outside our hearing threshhold, so we probably wouldnt notice that much

  • no, we wouldn't hear them, they would just destroy our ear drums. YOU'RE A MORON.

  • @steveodude6 ... clearly you are the moron , why do you stoop to calling people names, if the structure was airbourn and flying upwards at speed it would have no effect on our ears, if we were passengers in the vehicle the sound would be below us traveling downwards.. let people have their say without resorting to retard tactics eh?

  • @technocreep you'd need very big speakers for that

  • It doesn't have to. Sound waves don't HAVE to be in our hearing range. So it may be completely silent. Then again, we may need waves that are just the right power, so they might be loud. Who knows?

  • Remember sound waves need air to be transferred. In an vacuum it won't work. I think you have a great idea still. Just don't focus on the sound waves. Focus on the magnets and there magnetic fields.

  • Wrong, sound can travel in all particle mediums, a vacuum being the exception, sound actually travels faster in liquid because the particles are closer together. Even still the idea is still idiotic like the rest of this guys videos.

  • @crossey83 , Idiotic? didn't they say that about einstien before E=mc2.. seems like you are the only Idiot on this page, you should delete the 83 from the end of your name, add an "ed" and call yourself Crosseyed. you are blinded by your ignorance, at least technocreep is putting Idea's forward you twit..

  • @Quantomguy ...nice hahaha but yeah people stop the hating..

  • Hi!

    Had the exact same thought. But the waves will (in an ideal situation) cancel eachother out. (Phase-cancellation) Theres another thing to to. Rotate them vertically. Let them meet at the bottom were part of the energy make a "thrust" and part are distributing force to the resonance inside the craft:)

    Then you have to have money to buy material to build prototype. But lets don´t think about such boring stuff :D

  • I think you have an excellent idea here, but I have a small problem and I hope you can provide a solution... Yes, the sound waves will meet and high pressure sections will overlap and cause a large high pressure spot for an instant (thus forcing away the ufo), but low pressure sections will also overlap (at the next instant) and cause a large low pressure spot which will pull it back.

  • Hmm... Maybe if after each speaker emits the high pressure section of a wave (i.e. after it pushes the air) it moves back slowly enough that immediately after the high pressure spot, the pressure returns to equilibrium with the surroundings rather than dipping below which would happen if the speaker pulled back quickly. You must have more speakers since the time you must wait between each speaker's emission would make for a very rough flight otherwise.

  • If i were to try sound propulsion, do u think i need like expensive high tech stuff? I'm really interested in this topic.

  • You might ask college professors, or a professional, about what inexpensive materials might be used for your experiments, and where to get them. @gringomeyer

  • perhaps none of us would ever be able to pick up such an ubnormal high frequency.. nevertheless it HAS been done but the high powered gennerator was only lifting small light objects, so if you can scale up a very light ufo put a robust powersource on board and a sound generator system onboard as well and carry enough energy to self-propell.. it becomes a matter of weight vs energy - how many watts per gram..

  • Thank you for commenting! I like it when I can communicate with people on the same level, or at least close to it. Are you familiar with the nuclear effect. I'm not sure if scientists have yet coined this term, but it has to do with facsimilating the environment in which nuclear material will fully detonate, using only 1 molecule of nuclear material. It has to do with creating a high pressure/compression environment, much like gasoline is compressed before being ignited. Do you know of this?

  • I may not being using the correct terminology but, at what hmmm........freqency will these waves be at?

    A sound wave could be converted into a blast force?

  • Good question. To draw from real life, and believe me when I say that in 200 years just about all other physics which have not as yet been explored have been explored by my time period, think about Biophysics. How does a Manta ray or sting ray move through the water. Or, if you've heard of a Trikke carving vehicle, that would work too. Imagine each movement up or down, or side to side, is an opposing sound wave, and you've got the basics.

  • I should've actually said Aquatic Biophysics.

  • ok think about it... The only reason your getting a spike in ONE direction perpendicular to the waves path, is due to the fact that the pressure of the water below, prevents the spike from pushing downward. In any other condition, the spike would be in BOTH directions and thus creating equal force in opposing directions, achieving a whole lot of nothing...

  • Interesting, sound wave propolusion.

    I have thought about this before.

  • its a good idea in theory but in reality it would probly mess with the sonar and navigation of other ships and the noise polution would be horrible.its a good idea but probly not for practical use

  • Actually I had air vehicles in mind when I made this vid, but good point. Thx

  • con't... nothing to do with gravity.. go look for a video about an experiment regard the behavior of fuild without gravity in space, you can still see rise and depression of waves.

  • personally I doubt it will work. Since sound wave is a variation of pressure, it rise and fall and this means no net force. zero net force is zero accleration(no thrust). If you look at fuild motions, when waves hits, it rise to the peak, but it will fall back down. This have nothing to do with gravity... con't

  • What if there's a one-way release valve that opens at the end of every crest, to counteract the "sucked back down" effect?

    Hmmmmmmmmmmmmm...?

  • For every crest in pressure, there is also a trough. Yes, for a moment, the vessel would be pushed up but then immediately be sucked back down. The basic principle of lift is creating constant pressure differentials on the top and bottom surfaces of a vessel.y There could be a method of doing this with sound but it wouldn't be efficient.

  • I must admit there is something in it. I'm working on electromagnetic inertial propulsion system and working principle is a little bit different.

  • Wave fluctuation, perhaps? Gyroscopic? Oscillatory?...

  • oscillator is one of the parts. It relies on reaction of electromagnetic pulse with permanent magnet. pulse of unidirectional magnetic vector is a must. I've made some experiments and trying to design and build last final prototype. I'm seeking an elctronic technician to help :)

  • Electromagnetic vectoring instead of thrust vectoring to create motion, with one pulse stabilizing the vector of the other? I definitely wish you all the best. Now we're starting to get somewhere! It's giving me a technogasm just thinking about it. Are you going to do a vid on it, when you've got your patent issues out of the way?

  • Great idea so please keep up the good work.

  • Thrust from sound waves is most definitely possible; they're called pulse jets. However, they are not what you'd want to use at all. Their volume levels are enough to permanently deafen anyone who happens to be near and without suitable hearing protection. German V1 buzzbombs used combustion effects to make the audio-frequency standing waves inside the thruster, along with reed-valves to "rectify" the gas flow inside the tube so that it's unidirectional.

  • Interesting... Thanks for your input! @hoser4

  • Sound is a pressure wave through a fluid medium. There is no fluid medium in space (well, for all intents and purposes, that is; 1 hydrogen atom per cubic meter just barely counts as a gas!). So, I'm not seeing how any of this applies towards stuff in space.

  • HAARP was based on the old Nazi sound-wave weapon, just placed in conjunction to cause the plasmatic reaction in chemicals by matching its resonance. This does not in any way help levitate objects, in fact, this actually hinders anything that IS in the air (more of anti-air weapon). It is completely theoretical and even the tests done were inconclusive.

  • This will actually be the topic of one of my next videos, using sound as an anti-aircraft weapon, which leads into anti-spacecraft weaponry for those pesky aliens out there. Remember the shattering a glass with sound waves?

  • The positive end of the wave produces a negative sink afterward to cancel itself out. You would need to produce waves that are increasing positively exponentially to cancel out the prior negative wave...but that would mean the sound device would not be allowed to turn to center. As soon as I get my camera working, I'll post a video response to this in more detail.

  • Great. A work in progress. And remember, people are watching. So you're bound to be noticed, and will definitely be acknowledged for your contributions... @sabriath
