There were all sorts of gadgets to improve fuel consumption or even the whole "run your car on water" over unity energy scheme, which is still making the rounds in different forms like "free electricity."


"over unity" does indeed exist, according to science. (in the way [definition of it] that the groups of people out there explore the sciences of it, on forums or whatnot)

Established high level science and technology has invested untold billions into it, in the realm of open and known science and works.

We call it fusion.

billions. Tens and tens of billions spent. Still going nowhere.

Now, tell me that this phenomena that billions is spent on, exists no where else in the realm of all materials, atoms, elements and sciences.


One can't. It would be ludicrous to say that it exists no where else. Completely anti science and anti logic, it would be.....

Eg, an atomic weapon is definitely an over unity device. They've been around for 70 years. Most people are within 100 km/miles of an over unity device. The atomic rector for the local power company. The case for it is alive and exists everywhere.

Therefore.....

People explore and sometimes they find things.

Importantly....trillions of dollars and worlds of power and control...with a known extant history of being utterly, brutally violent.... are aimed against such intrusions into their realm. Cheap free energy changes everything and at the very least, turns their games to ash, almost overnight.

Those are the simple logical and easily observable facts.

No conspiracy or nutbar label required. It is easily observable to be as real as the day is long and the sun rising. :)

Ken you are being liberal with the name, lighting the fuse on a stick of dynamite becomes over unity. This does not stop Steorn, the MEG generator, electro-gravitics, the Nazi bell, etc. from being worthless nonsense. I think de-emphasizing atomic energy is one of the great tragedies of our time.

And my apologies, I consider anyone coming into an established community and requesting accommodations as having an agenda. Nothing personal at all, discussing moderation should be offline. I have BTW left forums where the moderation allowed certain offensive behaviors that bothered me.

Thank you Scott, I accept your apology without reservation. As a newbie, I think I'm allowed to be a bit bumptious without being slapped down too hard, but I do understand where you are coming from. If you must know, I too can spot someone with an agenda at a 1000 yards, but me? Nah, I have a life of my own and not in anybody's pocket, so I don't even think in terms of an agenda - that's what other people do - not me.

Glad to have gotten that one off the books - cheers ToS :)

When noise FIGURE measurements become too imprecise for tiny numbers, we use noise TEMPERATURE measurements, referenced to absolute zero. At zero degrees Kelvin, all thermal noise ceases. 30K is a low noise system.

These numbers are typically seen in RF amplifiers, and systems. When I worked on 4GHz TV satellite receivers in the 1980's 100K was a good system.

LIGO is a large scale laboratory with deep space receiving antennas capable of "hearing" very weak signals, due to the system's low internal noise.

Parametric amplifiers are made by modulating the parameters of a semiconductor device by a large RF signal. The semiconductor was usually a tunnel diode or a varactor diode. These could amplify without using resistors or a DC power supply, thereby eliminating two common noise sources. Common in the 70's and 80's, but today usually seen only in extremely high frequency RF systems.

We look at the whole "system" for it's ability to detect, monitor, and make some sense out of low level signals. The same is true of our audio "systems" and that system extends from the source to the listener's brain. I know that my hearing has a much worse S/N ratio than most due to severe tinnitus, so my audio system will never be as good as the same system with a different listener in the chair.

I understood most of what he wrote. I did have to look up "LIGO." Does that make me a "guru?" Maybe if this was an RF design forum, I could be considered an "expert" by certainly not a "guru."

In this forum I am well known for squeezing the most out of tubes. I am "knowledgable" in the solid state world, but a flat rookie in the DSP and speaker building world. NOBODY is an expert in all aspects of the Audio world....it's too broad and changes too fast.

Thank you for that. As a beautiful articulate explanation, I understood every single word of it - Respect.

Long ago, I used to work as a junior medical pathology lab technician, and became very adept in the purposeful necessity for small accurate measurements - as patients lives depended upon consistently accurate results from tests going up to the wards.

One thing that was drummed into us trainees was an understanding that our own individual knowledge base would become outdated, hence redundant, every ten years, and I have never ever forgotten this fundamental attribute of the advancement of science. That dogma is the death of scientific understanding.

Yes, I claim to be an artist, I am seen and somewhat recognised as an artist, but underneath, I am also a scientist in my outlook and understanding.

Hopefully, that includes audio! :p ToS

Sure Scott, as that is how they are looking at it. They've got an energy level of some sort, contained, in whatever fashion or nature....and their unlocking of it is 'economical'. Economical from their view.

and indeed the way that science has ever managed to move forward in difficult areas, is when large groups nay-say and hold sway over the common ground... and the other ostracized small groups die trying -over and over. And they finally get there.

We need more people doing their best to break the paradigm, to not feel ego comfortable in holding up and slowing the world down.

But, alas, most of what a human is built on -as a system of existing- is 'assumed realities', where assumption and norms in behavior are taken on and never examined. Probably 90%+ of a human is assumed societal and cultural norms of an unexamined nature. It's the only way a child can grow into the so-called adult stage. Otherwise not enough time, training and intelligence would exist - to make it happen.

Trained mimics, we are, that is why the rote teaching method of the 'Bavarian school of thought' system, which became the fundamental in engineering academia - even exists at all. Modern academia exists as founded, on these principal human aspects of life. No different than how one trains a dog -- repeat.... and it mimics. The vast majority of what a person is and comes from exists in this way.

I suspect it is used specifically to drive certain people nuts. There is a passive aggressive element to it exemplified in Dave's (Planet 10) assertion that downward dynamic range (DDR) is such a thing
Some people going nuts may be a side effect. From what I've seen time and time again, it is specifically for business purpose, if you get my drift. ;)
As for the audible sound that cannot be measured, there is still no example cited to this day.
 
As a practical matter, there is no way to verify all claims of what people may or may not hear.
Of course there are, double blind test and measurements.

Hi Fi is after all for people to listen to, and many claims as to what something sounds like may be useful clues to areas of a design that could benefit from some more work. As I said previously, the problem is separating out more reliable reports from less reliable ones.
Hi fi, by definition, is about high fidelity to the original source. In digital audio replay electronics, it would be the level of faithful reproduction of what's in the digital file.
 
Of course there are, double blind test and measurements.

They are expensive and time consuming. Nobody wants to pay for them, even in many cases for rather limited studies. Not going to happen for all claims, doesn't happen for enough as it is.

A lack of any practical way is enough. Theoretical ways that aren't going to happen are of no utility.

Faithful reproduction would be a great start. It's not clear that its ever been done to the limits of human hearing. If you look at Sterephile reviews of the best dacs they have ever found, they all sound different. Which one is right, if any? (Not saying the differences are large, only that there are some differences that are audible to some listeners.)

I have not found a dac for me to listen to that I am satisfied is truly accurate. I know the best one I have now has a sound. That is a clue that they need more work, as I see it.

Hear hear.

There’s is a website around somewhere that lists deaths from energy derived from coal covering pollution, industrial accidents etc.

It’s about 50 thousand annually and climbing (China factor).

Nuclear about 10 a year and all industrial accidents (Johnny dropped his scanner on Fred’s head type stuff).

As for environmental impact, getting atmospheric carbon levels back down to 280 ppm will take at least 200 000 years.

But, I digress. Apologies.
 
Even if we had distinct Objective and Subjective sections of the forums, people with the opposing philosophies would still jump in to tell everyone how wrong they are.
They would to certain level but not to the fanatical level done by the pro shills which is what the real problem is on forums.
Maybe that's just the nature of online discussion.
It's inefficient for sure.
 
Fundraising is not my line of work, and I am retired anyway. Say, you aren't a fundraiser are you?
I've stood in supermarket entrances hassling people for good causes before now, I don't think this counts :). I was thinking of one of those online things people do these days........ What would happen though if it was found that these immeasurable things could in fact be measured, would the marketing men have to invent some other immeasurable but audible artefact? Don't answer that :D
 
I proposed, multiple times, now, in the blowtorch thread...the exact criteria to measure the unmeausreable, in audio. I explained every single detail and the why of each and then the result of the whole.

To make that problem go away, period, to never return.

No one followed up on it, at least not openly.

It would make audio very boring in the aftermath -- that... we do know.
 
quality of new threads going downhill

The "quality" is only as good as is the knowledge and experience of the members and their willingness to share their knowledge and results. Nothing else is possible. Without willingness to learn and work hard of the new members we can hardly expect better quality. However, there are many threads with valuable information and many members come with valuable inputs, this should be appreciated. Do not dissolve into useless pub discussion like here, that's all.
 
They are expensive and time consuming.
That's relative to who you ask. For those who have done it many times, it's not taxing.
Nobody wants to pay for them, even in many cases for rather limited studies. Not going to happen for all claims, doesn't happen for enough as it is.

A lack of any practical way is enough. Theoretical ways that aren't going to happen are of no utility.
There are plenty of it done by the audio electronics industry and the hardcore followers. It's often free to retrieve the results to read about.

Digital audio technology has surpassed human hearing limits long ago in terms of low level distortion and measuring capacity.

Of course, in subjective auditioning sessions. You can hear a difference from a same DAC if you subject yourself to such listening session.

I have not found a dac for me to listen to that I am satisfied is truly accurate. I know the best one I have now has a sound. That is a clue that they need more work, as I see it.
Other than malfunctioning or esoteric brand, the current crop of DACs are all audibly transparent way beyond what you can detect with your ears.

Looks like we are going to disagree on the statements above. You appear to have already firmly decided what you believe in the above areas. In that case, arguing with you would not likely be productive. More likely to provoke backfire effect.

You have been on my ignore list before as I recall. Welcome back, and good day.
