"Mechanical power in is calculated from torque and speed of the driving source blah, blah, blah...
Ron

RIGHT FINALLY!  

MECHANICAL POWER IN IS CALCULATED FROM THE TORQUE AND SPEED OF THE DRIVING SOURCE - I.E. DRIVE SHAFT.

T 

[capthook]

A GENERATOR CONVERTS MECHANICAL ROTATIONAL POWER TO ELECTRICAL POWER.

1) THE MECHANICAL POWER IN = TORQUE x SPEED x 2PI

2) THE ELECTRICAL POWER OUT = V^2 / R

And HOW do you get your mechanical rotational power (1)?
You use ELECTRICAL POWER IN to achieve your mechanical power.
WHY DO YOU CONTINOUSLY REFUSE TO INCLUDE THE ELECTRICAL POWER IN?

"HE AIN'T HEAVY - HE'S MY (myopic) BROTHER(S)".

PERHAPS COLESTON WILL ELABORATE MORE ON THIS WHEN HE GETS BACK HOME TO TORONTO? 

HE SPENT 4 HOURS IN THE LAB - WHILE HIS FIANCEE WAITED IN THE CAR - HE EVEN WENT OUT FOR A SMOKE AND DIDN'T EVEN INVITE ME.  I FINALLY I HAD TO KICK HIM OUT SO I COULD GET SOME "REAL" WORK DONE AND TO SAVE HIS MARRIAGE.

I HOPE IT WAS WORTH THE 10 HOURS OF DRIVING COLESTON? 

CHEERS AND THANKS FOR THE BEER INVITE!

Myopia as metaphor:
The terms myopia and myopic (or the common terms short sightedness or short sighted) have also been used metaphorically to refer to cognitive thinking and decision making that is narrow sighted.

Wooo wooo, I'm back now, so first just for the non exiting bits.

A client of mine loaned me thier '02 BMW 328i, so actual driving time was 3.5 hours there, 3 hours back. Avg speed was about 180 the whole way, which was very exciting. There was a sweet bit on the way home where some chick in a yellow mazda spent about a half hour trying to catch me, then about 20 minutes trying to pass me while I weaved like a fucking basketmaker at 180+. Epic failure, I wish I couldve followed her home so I could lambaste her with a healthy dose of smacktalk, but she never even got a chance to even attempt to pass me. Booyeah, and then there was the 300C that attempted to play for a while too, but the driver was thoroughly outclassed, just didn't have the same youthful reckless abandon I guess.

I didn't realise you smoked, and in my defense how am I supposed to remember social niceties and politeness when smoke is coming out of my ears from the runaway oscillations in the ol' brainpan?

And I appreciate your concern, I should specify that technically she is only my girlfriend because I haven't given her a ring yet, but you'll be invited to the wedding, shes a keeper. And she was only in the car for like an hour, the rest of the time she was walking our dog.

PLEASE TELL US HOW YOU WOULD GO ABOUT EVALUATING THE PERFORMANCE EFFICIENCY OF A WIND GENERATOR?

Power in the wind: (density of air) x (turbine blade diameter)^2 x (velocity of wind)^3 x (a constant = C)

power in = d x D^2 x V^3 x C  What about that constant, C?

It's there because what we are really interested in is

the Area swept by the blades of diameter, D.

The area is calculated by multiplying the

number Pi (approximately 3.14159)

times the diameter squared

divided by 4.

This is the

power

IN.

THE DRIVE SHAFT

Then measure your power OUT. Divide: OUT/IN = Efficiency

IF THE DRIVE SHAFT IS NOT TURNING WHEN THE WIND IS BLOWING 100 km/hr THERE IS NO POWER IN & NO POWER OUT

So for what Thane mentioned a simple frequency doubler will up the max RPM's quite a bit. Space vector modulation to a 3 phase AC motor will put the variac and the split phase motor out to pasture. See ya!

With the new mosfet switching speeds I betcha I can beat any world record for a spinning wheel. 500K RPM? A mil? Just depends if we can get the rotor (flywheel at that stage) made to the same or higher level of precision as hard drive platters.

But none of you poor buggers got to hear the thunk. It was freaking incredible.


And all the Pin vs Pout is completely irrelevant at this point, tis merely a prototype. All it needs is a few more coils and a 3 phase motor, then you can do a power in vs power out analysis that actually means something in simple terms.


It doesnt mean anything at this point because the Pin isnt enough to spin the rotor at 3400 rpm. Just cant do it. (well maybe if you span it with your hand and allowed it a couple days to accelerate it just might be able too, but I dont think so.) The thing running is using more energy that is going into it. It consumes over unity. Woah!
I would say give Thane more time to put the new properly made (no offense) coils in, and start harvesting usable energy from it.

Anyway, in my personal opinion after an intense analysis of the system this is the most important breakthrough in the history of electronics. Since Faraday discovered the law of induction.

And its so simple, magically turn an inductor into a capacitor. Wooo. (no I'm joking about the magic)

OMG I just get tingly thinking about it hooked up to a SVM controller and a 3phase motor, with a larger rotor with 4-5 times the magnet density AND a ton more coils harvesting usable energy from it, and eventually no motor at all but I'll leave that one to Thane, I think he wants to get the 3phase one done before physically making the evolution, but he has it all planned out, holy jesus.

Anyways, what a great trip. Oh and  my lady and I went to see watchmen, that was a freaking crazy movie.
