Trying To Fake Thermo

A few laymen can get _some_ kind of understanding of thermo. The anchor of NPR for example, has figured out how to avoid saying stupid things on the subject.

But if most people try to fake knowledge of thermo, they will out themselves in a few lines.

Here it's one line:

You have any reason for thinking that it wouldn't scale?

Of course not.

That's because you thought you could fake a tech background.

Sorry, Charlie, that ain't gonna happen, certainly not with thermo.

Now, if you don't want to get a Pell grant or work your way through college or even go to the library and read up on thermo, then go back to reading your Harliquin romance novels.

And typing:


"Show your calculations"

This thread reminds me of a comic:

I thought it was hilarious, but my wife (not an engineer) didn't get it...

Wow, I like that guy's stuff. Have you shown your wife #162?

I'm still trying to back calculate the title of the Harliquin romance novel that inspired her theory that scaling up adiabatic engine systems could be a problem.

Bret, thanks for the link. I read almost all of them. The later ones are funnier; some early ones I couldn't get at all even with the flyover hints.

Zinc or magnesium, how? Magnesium reacts with steam to yield hydrogen, but now you have to 1) provide water, and 2) heat it to steam.

Maybe sodium or potassium metal - those react with room-temperature water to yield hydrogen gas and the metal hydroxide. But still, you need water: so you have to fill up twice: once with the (hazardous) metal, and once with water.

Then again there are energy density considerations... compare the volume and mass of these alternative fuels with those of gasoline.
