Regarding the performance of my newly designed turbine

I warned everyone already. I will go nordic!!

No more fluff accepted.

You do notice however how I keep composure and stay polite.

hmm ok then I am pretty sure that is not how the vikings did things back in the day. :)

Nah, I do not feel anyone is being too rough. One is just being rightfully skeptical and I am just laying the ground rules to newcomers if they would like me to be interested in actually following up on their claims.

The amount of times I have offered to only share STL files and make the peers pay for the printing of it is about 0. Let alone the discussions possible after the fact that no no noyour printer settings were not correct. blah blah.

All I ever do is offer my whole setup for peer review including transport costs. Done it many times this offering. And will do so again.

There is bound to be a moment in time where the results get good enough for one to be willing to peer review it.

Don't think anyone is going postal. Just rejecting claims that are physically impossible. I haven't the first clue about the detailed design of wind turbines but I don't need to test such a claim to know that it's false.

No machine can be > 100% efficient (conservation of energy). Practical wind turbines cant be > 59.3% efficient because you have to leave some energy in the air flowing through the turbine so it can get itself out of the way of new air flowing in (conservation of mass and momentum). Betz did the math proving that over a century ago.

Anyone who thinks that the world of science is some kind of gentle academic paradise is sadly mistaken. It's brutal. You put something out there you better know what your talking about or you'll be torn to shreds. This forum is all sweetness and tolerance in comparison.

Yeah, listen to Brandnewb, he's been at it for years, and all he has to show for it is a pissed off wife.

It is going to feel so rewarding when I will not even tell one (other than those that read my logbook) what had been done. One either hears of it or chooses to not want to learn :)

Respect.

But one thing can no longer be uncertain about.

The beast is a Beast!!

I call that one massive thing to show for in my books btw. ;)

But all was meant tongue in cheek yes?
The amount of time and money I put into this to do it in a manner that makes for no debate possible is rather large. Not at all like what we see here.

So fun and jokes are cool and all but not let us slide into mistakes. I will watch out for those. :)

A little common sense from someone in this forum. People here want to talk much, but doesn't want to do the work necessary to verify any claim.

I saw no real good argument here yet. Perhaps I am indeed not intellectual enough :(

Anyway I have said what needed to be said and I will go back to making for something to show for.

I wish more of us did the same!! Not only arm chair complaining

You have it backward, you're the one not doing the necessary work.

You are claiming something that violates fundamental physical laws (conservation of energy, mass, and momentum) as embodied in Betz' law which has been peer reviewed and validated thousands of times over more than 100 years.

You are making this claim without putting in any effort to explain why this could be possible, or even explaining how you did your calculations. Instead you want us to go through the work of proving you right (or wrong). Why should we? Would you?

Suppose I came to you and claimed the moon was made of green cheese. Here's the design for a rocket. Go build it and fly to the moon to verify my claim. What would you say?

Pretend I don't want to watch a video, and explain to my like I'm five: How do you calculate power from RPM with no load?

yeah, not going to happen. :)
I appreciate his 3d model and printing and spinning with a fan. If it were hooked up to a genny and made a bulb glow it would be nifty.
Other than that, any speculation from his testing is just that.
OP, on to the next step. Do something with your model now.
 
That stupid video: He claims 1.2 joules of energy stored in the rotating turbine, so the turbine is a "capacitor" that has been charged over 10 seconds to 1.2 joules. That has no practical use. It needs to transfer power, via the shaft, to some device which can measure the power captured after reaching operating speed. What would happen to his math at 5 seconds or 100 seconds with his setup? It would not support his narrative.

Does the cheese have to be green? I might fly there for a moon's worth of white, yellow, orange, or even blue cheese, but not green cheese.

So 0.0003333333 WHR stored as rotational kinetic energy? That says nothing about input power (from the fan) or potential output power, though I guess it would light an LED for maybe a minute with the appropriate 100% conversion generator head (you know, from Temu) and frictionless bearings (AliExpress). No, wait, the other thing.

Yeah but YOU have to build or pay for the rocket. Unless your name is Elon M or Jeff B that's prolly not gonna happen.

And the probability that the moon is made of green cheese is higher than that a wind turbine can be > 59.3% efficient. A green cheese moon is not a violation of the conservation laws. A race of now extinct hyper intelligent alien space cows could have been using the moon as a galactic garbage dump for their spoiled cheese for millennia, and then covered it with a little dirt layer like we do our landfills. We don't know....

Just for you, and crowz, out of respect I changed my mind,.

I will update here as well to what I have to show for.

I just broke my rule :(


My god how can one like you and crows be so out of touch by just blurping soming like that?
Have you any empathy in your soul?

I have no idea what your talking about but you have my blessing to only update in your thread and not this one if that helps :)
 
hmmm measure extremity you need? why.. but..

not defined a man is by his writings. but his actions by.

So unless you have something really compelling to add to this d&*k measuring competition. I suggest we keep cool and stay low.

If you really want to arm wrestle we can do that outside of this thread.
 
Wind turbines and not violating the law of physics.... Lets see if we can get to those 30 pages?

My personnel experience with wind turbines, installed everthing from a 500 watt to 10 Kilowatt and helped on windfarm installs of 500 Kilowatt to 1 Megawatt turbines.
Worked on one project that was a repower of 48 each, 1 Megawatt turbines. Life of original 1Mw turbine was 12 years.
They all had this in common, blade flutter caused by turbulence. The interuption of smooth laminar flow of the wind, which is another way of saying the blades were exposed to large eddy currents.
Failure of turbines, blade flutter caused stress and vibration at harmonic levels that were not considered in the design. Or the harmonic caused vibration was considered and deamed to costly to overcome in the building of the turbine to make it "cost effective" for its lifetime (MeanTimeBetweenFailure).
Only wind turbines that I have personel experience with that is more than 15 years old and still producing power is the Bergey 10Kw. They have been taken down once for blade repairs that were part of regular maintenance.
