Re: Insulating the cold side

The second law has several meanings. They all agree.

Re: Could Both Carnot and Tom be Correct?

Yes. It's 25% higher.

300x1.25=375
300x1.20=360

You are starting at 300. And adding a percentage.

"375 is 20% higher than 300

Moron."

You will never get simple arithmetic correct if you keep insisting on you fallacy.

Re: Another Stirling gamma anomaly under the radar

I understand what you are doing here. Kudos. Modeling an engine by finite elements with each element having a set mass of gas. Excellent. It seems like it might avoid problems with set volumes. It might even allow ultimately mixing of the gas, and flow modeling. Excellent. Separating hot processes f...

Re: Insulating the cold side

A goal is to combine a power generator with a fuel source. Gaseous and liquid fuels are relatively straight forward but need to be transported. Solid fuels seem more difficult to self regulate and feed, but often close at hand in remote areas and often waste products. A self feeding and regulating b...

How can temperature be equated with energy transfered?
Because the gas has a known heat capacity.

Quite rightly so. Heat capacity, as you just pointed out, is the bridge between temperature change ∆T, and energy difference ∆U. Q=∆T•C .

Thanks.

Re: Could Both Carnot and Tom be Correct?

Tom is so tough that when there is no one around to fight with, he starts a fight with himself by baffling himself with his own bogus banter. Starting at, for example, 300°K ambient Raising T-hot to 375°K is an increase of 20% 375 is 20% higher than 300. Subtract 20% from 375 leaves 300. Last I chec...

Re: Could Both Carnot and Tom be Correct?

No, actually the second law contradicts the first. Clearly you are mistaken. First law : Energy is conserved. You can only get out what you put in. What you put in : Qh What you get out : W and QC. W + Qc = Qh <<< What you get out equals what you get in. First law. Also can be written : W=Qh-Qc Sec...

Re: I'd like to recreate Tom's experiment

Like, for example: if an ice cube between two engines never melts until the engines' bearings wear out after six months or however long that might take. I'm glad you are still working on it and wish the best. I'm very curious what you'll find either way. I'm also glad you still have your sense of h...

Stirlings have the potential to use less fuel than a peltier.

Re: Could Both Carnot and Tom be Correct?

Yes Tom and Carnot can both be correct. If Carnot had access to a Stirling cryocooler he likely would have update his work to reflect his new discovery, and Tom would never have had to take interest in the matter at all. If Tom tries and fails to build a self cooling machine he might think it impos...

Re: Could Both Carnot and Tom be Correct?

I guess Tom concedes being the one in error. What a disappointment. Attacking a poster instead of the science. When you finally figure out why you are in error, by failure to build your Tesla cold hole and agree to be civil, I will be expecting a very deserved apology for being so mean. As of now al...

It's just a pressure gauge and a recorder, compared with a, crank position sensor and recorder. Arduino. Good luck living in your lack of data. Why should I provide you with data. I'm not the one trying to understand how these engines work. Sorry if they work differently than you wish them to run. I...
