Uh, you neglect that the original poster said WattHOUR and Joule. And the HOUR was “Implied”.

So, exactly what IS the difference between a WattHOUR and a Joule? And what is the difference between an “implied” Watt-Hour and a Joule? Are resistors measured in Watts? or WattHours? Or Joules? Or Watt-”Implied Hours”?

watt-hour and joule are both energy units

1 watt hour = 3600 joules

Kevmo, I see you posted up a storm after everyone went to bed.

“But, next time, try to avoid the bowlsheet of saying that the coal industry sells their crap in Joules per bucket or anything like that. It’s a ridiculous argument. It appears that across the board, from 1W to 1MW, EE’s go into shorthand mode when they say Watts but mean Watt-Hours. But if you think that this means Mouser is shouting “SCAM” by following this shorthand, you’re simply way off.”

Uh, the coal industry does work in BTUs per car load or metric ton, somewhere along those lines. I also happen to be into railroading :) Model railroading in reality, but I love reading some of the real business info about coal, since it is still one of the railroad’s major cargos. Remember, BTUs convert directly to Joules, they are both energy units.

A given coal from a given mine, with a given moisture content, will burn in a boiler and produce X amount of heat energy. Another physics thing you should learn about. The entire system can be expressed in Joules. Because, once again, Joules are energy.

“Here’s a power calculator I generated for the industry:
http://www.sipex.com/files/ApplicationNotes/ThermalCalculator.xls”;

Link doesn’t work, and I wouldn’t trust it if you were the actual author. Sorry, that’s the breaks, given what I have seen of you so far on this forum. Besides, if you really know your stuff, you would know that “power dissipation” is actually based on Joules, since power without a defined delivery time, makes absolutely no sense. It is just expressed in degF/Watt dissipated, to make thermal calculations somewhat easier for the engineer.

“***Then it would appear that your pulse would last at MOST few seconds, not years. That’s all you needed to post. As you say, “Oy! That pretty much explains his knowledge failure, right there in that one sentence.”

Uh, no again. Never seen a coal train stop in a few seconds. Those locomotives use dynamic braking, and they dissipate heat through massive fan cooled power resistors for minutes on end. Even at the lumber mill level, servo trays running 100hp cutting motors across the planks easily stress resistors near continuously.

You see, in thermal engineering, more than the ohm and watt requirement are important. You just haven’t thought big enough, or oversimplified the problem in your head.

“I don’t think you got it any more than the other guy. He says that 1MW means 1MWH, that it’s a short-handed thing in, well, the coal industry. And all of us should know how the coal industry talks about such short hand because, well, coal used to be delivered by hand to each household or something like that.”

It’s you that isn’t getting it. Power systems like generating plants or nuclear reactors are rated for continuous operation. To determine the energy developed by such a system, time MUST BE A FACTOR. Energy without time is instantaneous power, and a absolutely worthless number to have around for a power plant.

“You seem to have gone the exact opposite in terms of your understanding. Are resistors measured in Watts? Or is it Joules? Well??? Where is the “Joule” setting on your multimeter? I thought for a brief instant you actually might know something, but ... sigh... it turns out you’re just as ignorant as many of these other skeptopaths.”

Again, power resistors have everything you need to calculate the limit of energy you can ask them to convert to heat and dissipate. This is Joules. Joules. Why don’t you just go look this term up rather than beating around the proverbial bush? Anything related to thermal dissipation of power, deals with Joules. Yes, electrical resistance is in ohms, but the derating values are VERY VERY REAL. You aren’t going to stop a locomotive with the calculated max watt power resistor for a given resistance. You will melt it down. The resistor has to be able to take the full ENERGY load (which is in Joules) and convert to heat energy.

“Q: How many bandwagons must a skeptopath jump onto before he feels superior to others who have more knowledge than him?

A: You tell me.”

I’ll bite. Zero. Because you have yet to prove that you have more knowledge than me. Though I would say initially I gave you the upperhand on LENR physics, but not anymore. You are just too ignorant on the whole of basic physics.

“Maybe if you answered the questions of how resistors are measured, where the “Joule” setting is on a volt meter, and the power density hypothetical posted, we might think you could make a point. But instead, you seem to persist in your ignorance, as if that were some kind of virtue.”

Once again, I really hope you get an education before working on power electronics.

“Tell ya what. If you answer the power density question, we can get down to whatever units you want to discuss.”

Oh, you want me to bow to the black box Rossi is pushing but can’t demonstrate either commercially or convincingly to a small platoon of 7 scientists? No, won’t be agreeing on that today. Don’t care how many people you scam in intrade, etc. E-Cat is dead, and you know it, even if you can’t admit it. He continues to burn through people’s hard earned money, probably on caviar and fine drink, while building these black boxes that he refuses to allow anyone inside of. Definition of con artist. Just like Blacklight. Patent it, let the secret go. I mean, people would find out anyway. I’d give it 3 hours before a instructable about how to tear down your e-cat would appear on some howto website, if such a thing actually existed at all.

The reason he won’t release is because the free “investment” money ride would be over. No more caviar and champagne.

1 J = 1W*s = 0.000277777778 watts * hour

That you don’t know this is further proof of your lack of any professional knowledge of physics or engineering. I was hoping you’d at least trap me on some nuance or such, but you have nothing. Zilch. Nada. Which means every god you pray too in free energy other than the God of Israel, I definitely mistrust. I guess we are lucky you are so unprepared to forward your thoughts. Probably has saved many from the scams you love forwarding along.
