sonofusion

[secondarychaos]

@ProjectEnergy001 - those are great examples of fusion induced by gravity, but sono- implies sound. Stars do not require sound.

I wasn't implying that SBSL (or similar Acoustic cavitation) cannot produce fusion; in fact my employment status banks on it, however, producing a collapse violent enough in a glass is comical, unless you can tell me how you channeled quantum tunnelling, etc.

@dreamyear There are vids of sbsl (mostly high speed), but those that take them don't usually share.

[secondarychaos]

Please remove the title "sonofusion". you're insulting the intelligence of the general public, let alone the science community.

go do some calculations on the heat of fusion and tell me how hot that beaker would get at high frequency fusion.

[ProjectEnergy001]

@secondarychaos I couldn't agree more with your post. SBSL is not sonofusion however, if anyone wants to see an example of sonofusion, just look at any star or sun above your head.

[777static777]

@ProjectEnergy001 that would simply be an example of fusion; not sonofusion.

[jonzflicks]

A remarkable video. It actually took less time than the paint on my back door to dry.

[GzusCriest]

i cant put up a link here but there are a few vids on youtube about this

try "sonoluminescence - exp. in open campus"

Heh.. another way to look at the relative dangers of fusion versus fission is to think about a conventional oil fired power plant. Inside the house sized combustion chamber, you would become a cloud of ash in seconds flat, so it's extremely dangerous there, too. A fusion reactor is about that kind of dangerous in the sense that sleeping on the reactor core would get you a lethal dose of radiation in a few days or a week. In a fission reactor, it would be a few hours.

[RyuDarragh]

Oh, sorry, beyondapapermoon. Forgot to explain neutron dangers. Neutrons can induce radioactivity in other elements by a process called "Neutron Activation". Metals decay, organics experience soft x-ray and other ionizing radiation effects. Ever heard of the "Neutron Bomb"?

If you're curious, look up "Helium Three Fusion" to see what it takes to make neutron free fusion work.

Fortunately for Nuclear Fusion, the induced radiocativity, though dangerous as it's operating, is also temporary.

[soylentgreenb]

I've heard of a neutron bomb and they're quite useless.

A neutron bomb is simply a tiny thermonuclear bomb designed to let as many D-T fusion neutrons escape as possible. The purpose is to destroy tanks which are very resistant to blast and heat.

For unshielded people the lethal radius for neutrons from a neutron bomb is only slightly larger than the lethal radius from blast from a neutron bomb. As we are in no danger of a soviet tank invasion they're pretty much a historical curiosity.

@soylentgreenb for the ones u drulle about bomds go f-urselfs.

When a neutron decays, it releases a proton, an electron and a neutrino (the gluon can't exist alone, so is changed into a neutrino as it decays).

In fusion, therefore, many protons are converted into neutrons by electron-proton collisions and may of those combine with the now free protons and electrons to make a stable atom of Helium.

But, the process is not perfect. Loads of free neutrons go flinging around. That, by the way, is how Tritium decays.

[RyuDarragh]

I, for one, would have loved to see sonoluminescent effects be able to generate fusion energy as this video implies.

Despite the folks thumbing my comment down, I still feel iIt's a solution looking for a problem.

[beyondapapermoon]

this video actually implies nothing except for a beaker in front of a picture of an oscilloscope with blue and red coloring. There is no actual SL shown. SL has no spectrum characteristic of fusion. If it did, it would be the hottest topic in solid state physics. please, do some real, hands on experimentation, and stop fear mongering.

[RyuDarragh]

Fusion can and will produce dangerous levels of neutron radiation. So much so in fact that the vessels will need be replaced periodically. The only way to avoid that is to use Helium 3 or another cascade of fusable elements where the neutron is not generated or is absorbed by another nucleus.

Containing a fusion reaction is also damn hard. We can live with the innefficiencies. But, yes, it's also not a chain reaction based event.

[beyondapapermoon]

what is the MECHANISM by which fusion will create neutron radiation. Also, what is the damage of a neutron, i.e. A neutral particle with a small mass? Alpha particles are charged (+2) and can be stopped by a single piece of paper. Please explain.

[RyuDarragh]

Simple enough, beyondapapermoon. During fusion of Hydrogen, whether it's primary isotope or Deuterium (one proton, one neutron) or Trtium (one proton, two neutrons), something has to glue the protons together, and that is always a neutron. Neutrons only *appear* neutral at atomic distances, but at nucleus distances, they have many positive and negative poles. This is due to their being composed of a proton and an electron bound together by a gluon.

Fusion in water = BAD IDEA. Hydrogen Hydrogen fusion releases Neutrons. Neutrons induce radioactivity in Oxygen (water is H2O, after all). At best, from the spectrum, sonoluminescence is genrating around 20,000 degrees. Nowhere near, by several orders of magnitude, the temperatures needed for fusion. It's a solution looking for a problem.

[beyondapapermoon]

in the sun, the sheer number of protons makes up for the fact that over a million collisions, only 1 fusion reaction will take place. combined with the knowledge that the sun is 4 orders of magnitude hotter than SL theories guess (somewhere between 10000K to 100000K, depending on what mechanism you think causes it, either blackbody radiation or bremstrahlung) shows that SL cannot produce fusion. At SL temperatures, the chance of proton tunneling through the coulomb barrier is essentially 0.

[beyondapapermoon]

what IS happening in SL is a concentration of energy. Using RESONANCE of acoustic waves, and the fact that relatively incompressible quartz matches the acoustic properties of relatively incompressible water, which allows the highly compressible bubble to absorb most of the energy inserted into the system. Main idea in SL: Resonance.

[beyondapapermoon]

also, i forgot to add, Fusion is not dangerous! fission and fusion are two separate concepts. In fission, the amount of neutrons released can become supercritical(more produced than used)leading to a chain reaction. In fusion, two protons joining together will not produce anything harmful. either the product is stable(a-particle, carbon) or it is unstable and it flies apart. also the materials needed for fusion are inert&plentiful(hydrogen). but we do not use fusion b/c it is energy inefficient.

[digitheadman]

Ditto, what am I  looking at or looking for?

[cyberscann54]

ok after a quick Google search I understand the concept and theory of sonofusion which is a great idea and all but a video of a picture for 1:30 min is a complete waste of time I like most of your videos but to watch a video of a picture with a basic description off to the right is a waste it needs more a lot more if this video gets 960 views it will have wasted an entire day of the human race other than this video keep up the great work

[dreamyear]

there is no video clip of sonoluminescense.

the chain reaction video clip is close but not real. this pic is better.

[cyberscann54]

the chain reaction clip may not be real but it is the most realistic representation of what Sonofusion is and how it works

[777static777]

@dreamyear there are MANY video clips of sonoluminescence out now... so cyberscann54's comment is valid; this "video" is a waste of time.

[cyberscann54]

Ok what am I looking at what am I suppose to see?
