...for an even CLOSER shave! ;P

[broli123]

If you touch that, would your hand explode?

[wongy91]

@broli123 LOL u made my day

[NOBOX7]

@broli123 lmao

[Thetruthishere11]

Piezo?

[ussiable]

It is very interesting

[joelito101]

My 5 year old right away saw a light saber.

[jeff92677]

I was part of a group that created a hull for a racing sloop that had a shape near the bow that would grab air from the waves that was caused by some turbulence, and the air reduced drag along the hull that with laminar flow would slow down the boat through the water. Air bubbles do reduce the drag by eliminating or reducing laminar flow and associated drag. Kind of like making the hull "stall" in the fluid. Less drag when you need it.

[Beamshipcaptain]

The water molecule can be dissociated with RF energy at low power. Just vibrate the water moecule at its resonant frequency.

[jeff92677]

That would be "boiling" -- this is different, it's Sonoluminescence. Look it up on google.

[unambitious]

I'm pretty sure this isn't Sonoluminescence, rather like an ultrasonic humidifier, it vaporizes the water. On the same path, but not there yet.

Make a torpedo that creates cavities of air around it to reduce friction :) .

[b0utch]

can we use this to separate hydrogen and oxygen with less energy making the free energy possible!?

[ABaumstumpf]

no, it only vapors (it only turns from liquid to gas) free energie will stay impossible , use wind and solarenergie, they work

[b0utch]

ever heard of Stan Meyer!? just a question like that..... still not sure if it is true but it seems logic that using the correct electric frequency to cause resonance to facilitate splitting HH O

or Nikola Tesla project to haverst energy from the ionosphere.

Impossible is not a word that I like.... humans have been hearing and saying that word for century and a lot of them were wrong!

[ABaumstumpf]

i dont like impossible my self, but there are to many proofen laws of physiks that are against free energy. U sure can get energy FOR free, like with solar (i allready said that)

About Meyer: i heard of him: claiming to build a overunity engine and coming with lame exuses when it should be tested,....

[b0utch]

yea anyway he is dead! either he just died or he got poisoned by the arabia corp who wanted to buy is silence.... is it tru I dont know.... but I like to believe that theres a way to splitt hh o with a minimum of energy using the correct frequency.

I like to think its like breaking anything for the correct frequency it can be really easy, just like breaking a glass with sound, the exemple is gross but the idea is the same

[crippled82]

youtube puharich

over 100% efficient.

[MightyJustas]

Awesome, looks like a real fire!

[tjgame2]

Check out the globe it makes on the bottom at 0:05-0:06, it would be nice to see it run at that freq.

[pauua]

what's cavitation?i'm not english.

[WanderingWolfe]

Ultrasonic Cavitation is the creation of microscopic bubbles within water by use of high frequency sound waves. (Making the bubbles is cavitation.)

What this is demonstrating is that, when these microscopic bubbles collapse, there is a luminous energy release.

Thus the Tesla-esque light banding.

[alwinovich]

dude if he doesn't understand cavitation

he isn't going to understand your explanation either

[cvdwalt2000]

is this what happen in big diesel engines? i have seen the cylinder walls on coolant side full of tiny holes.(if you use the wrong coolant)

[MrBillTroop73]

Think of Cavitation as where water is ripped apart by a vacuum with such force that some of it forms a gas bubble, or even a lot of gas bubbles, in the vacuum left behind.

Cavitation is often seen in the wake of boat propellers as they spin fast through the water.

[madddann]

U are doing with sound, what Tesla was doing with electricity... good job! Now take a step further and apply this inside a sphere.

[grenouil1970]

Super !

[kreeger195]

Diagnostic ultrasound has been proven for the last 50 years to have NO bioeffects...

[TomInTheSky]

Diagnostic ultrasound works at much lower intensities. Industrial sonication equipment does have a quite substantial bioeffect on processed materials. It is proven to inactivate enzymes or kill microbes in liquid food, such as juice or sauces.

[therealgeeza]

what is inside a cavity?

[ManTigerBMW]

vapor.. if water is cavitating then it would be steam..

[therealgeeza]

but steam implies the water has 'boiled' ultrasound does not heat the water - think back to the last time you had ultrasound at the dentist. so how can steam be inside the cavity? i think it must be something akin to a vacuum.

[Tarzbloke]

Liquid does not need to be heated as we know it in order to boil.

Lowering the atmospheric pressure causes liquid to boil/vapourise.

You've never seen that old science trick where water is made to boil at room temperature? It's similar, but not close enough for an exacting analogy.

[chevy668]

Actually I have an ultrasonic mister Im foolin with, and I made a container too small and melted the the top of the plastic straight through., Then dumb me stuck my finger in the stream and nearly burnt my finger, IN WATER!!!

[b0utch]

isnt the cavity a vacuum!? I mean its empty, isnt it!?

[ABaumstumpf]

ne empty, just gasform, the liquid turn to gas cause of too low presure at some points, thats caviation.

[RyuDarragh]

Not sonoluminescance. The glow comes from the light mounted on the end of the metal part. Sonoluminescence takes much more power and has a blue color.

[magonirico]

Wonderful!!! :)

[ToucMyBiceps]

Look better than a lava-lamp

[Spaventacorvi]

LOL

[teojm37]

what exactly am i seeing?

[silverska8er]

sonoluminescence

[silverska8er]

tiny bubbles imploding and causing light

[Bob7k]

That would make one hell of a desktop version of the lava lamp. "Hey jim, check this out!" BZZZZZZZZZZ

Id buy one, um, how much did that thingy cost?

[angelcruzpr]

Any practical use?

[georanson]

it can be used to move in solid or gas mediums with much less friction thus meaning less energy wasted

[Bratbaticus]

Breaking down simple industrial wastes.

Those bubbles have huge pressures and temperatures despite their size.

[marek0086]

nice!

[cillantro]

It can be used to produce upto 1000s of gallons of biofuel a day!

[angelcruzpr]

Give me more info please. Is this application documented anywhere?

[cillantro]

Yes!u can get more info from wiki!

[msqtube]

ok, nice, ... but why do this at all?

[HielscherUltrasonics]

The cavitational impact can be used to reduce the particle size of materials, such as nanomaterial agglomerates or pigments.

[apeshkov]

what is the peak-to-peak amplitude of the sonotrode?

[HielscherUltrasonics]

for this setup approx. 25 micron (peak-peak). The amplitude can be changed by means of different booster horns and electronically at the front panel. Therefore, amplitudes from 3 to over 170µm are possible using the UIP1000.

[apeshkov]

Thanks.  What are the diameters of the sonotrodes used for different maximum peak to peak amplitudes that you mention (25 microns, 100 microns, 170 microns)?

[kalamar73]

Nice job.

[SGiHunter]

Is this process heating the water? Is there any hydrogen oxygen being produced/extracted at all?

[HielscherUltrasonics]

The basic law of thermodynamics applies: All power is finally converted into heat. Nothing is lost. In this case it is 1000 W of which 85% are mechanical output at the sonotrode. Given a volume of approx. 1 gallon, this will heat the water at approx. 0.2K/sec.

[SGiHunter]

Frequency and water type?

[HielscherUltrasonics]

20kHz, ordinary city water at 20degC, ambient pressure, the pipe is approx. 140mm in diameter

[Tibiamovies]

Nice
