Cavitation. The key to overunity?

[spinner]

I dont know much about cavity principle but ... are you sure that common resistive electrical heating element can convert electricity to heat with a +98% efficiency
Then what about direct current heaters wheres 3 phase  electrodes are direct in water  and whats bit more efficient mode of water heating - what is this "bit" then?
between +98%....99,9%   I have this system in my house, up to 12kW and I pay less than before when was common 9kW resistive element heaters.
I think that resistive electrical heating elements are not so high efficient as you described.

Hi, Khabe!
What kind of "electrodes" directly in water do you have? Are they not "resistive"?

A common heating elements are immersed in water, too. Due to an almost pure Ohmic impedance, they convert most of the electricity to heat. A bit is wasted on electromotive forces, inductive/capacitive losses, etc... A small part, that is..

FYI, there are several cavitation mechanisms... Which one are you referring to? Or, which one is OU?

How is your water heater powered?
Maybe it's just one of those old water heaters where electricity is wasted only to produce heat...
Why don't you change it with any of the FE heating devices widely known on the market? How about your Witts ultrasonic cavitation device?
What can be achieved with resonance? A Unity? This is known for many many years.....
I thought you said OverUnity...

Yes its an old water heater constructed by my dad 30 years ago and is also OU during the summer 'cause it runs on solar power and during the winter runs even on heated water from a furnace. so it is a combided device - electricity, solar, furnace. Happy now?
The Witts device is not "mine", i just came here in hope to find more info about it. And now that i clearly see how is the device supposed to work, i can say that this is preety advanced stuff.

BTW, a very common resistive electrical heating element can convert electricity to heat with a +98% efficiency. Can you do better?

Yes I can----- I can use a heat pump system and cut the electrical energy used in half to supply the same quantity of heat. Hmmmm, if as you state an electrical heating element is +98% efficient then how can a heat pump system do so much better?. This is because the heat pump system "moved" heat it did not supposedly generate it. Now ask your self one question---- where is the equivalency? Obviously an electrical heating element is "not" 98% efficient in electrical terms when half the input could deliver the same quantity of heat using a heat pump system----the proof is the electrical bills of everyone who has a heat pump system. What you fail to understand is the difference between transfering energy from one place to another and dissipating it completely in the media. A cavitation (implosion) produces a compression as an effect from the implosion, a compression produces heat, a compression must then expand relative to the media that surrounds it and in the right context pressure waves can be produced in such a way that the next implosion is reinforced by a reflection of the previous pressure wave resulting from the previous implosion. The effects are additive and are not dissipated completely lowering the power requirement from the input because the input does not drive the process directly it only maintains it. You are saying static conditions and dynamic ones must be equal when it should be obvious they simply cannot be.

Lol, you're "cheating" with the solar power OU... Ok.

Believe me, I'd like to see that "Witts device" working in reality exactly as it's seen on the video... But you already know what I think of it....
If you see it as a pretty advanced stuff, please, explain it to me.
Like I said, I see only a very good trick with an ultrasonic water humidifier...

Don't mess the heat pumps with a common electricity heaters. You have another source of energy with the first, but just a common electricity input with the later. Check out open/close thermodynamic system definitions.

What you fail to understand is that an "implosion" in cavitation is a just a consequence of a previous pressure compressions/"explosions", which are usually driven by a known energy source. And you have to pour great amounts of energy to produce an observable cavitation effect.

I'd like to see an reproducible experiment which shows an easy measurable water heating by "cavitation". Do you want to try?

Oh, don't mix cavitation with a sonoluminiscence or even sono fusion....
