Linear kinetic energy is frame dependent.
Is rotational kinetic energy frame dependent? :dunno:

Pretty sure it is.  If your frame is the edge of a rotating wheel then ....

But that topic has more to do with making the house tight / energy efficient.

My focus at the moment is learning how to manage the actual stove better.
It may not seem obvious, but having all your air coming from below or from one area is not always the best, especially with wet or non-seasoned wood.  If you see vapor or smoke pouring off your logs then you need more air, but sometimes the best addition is just above this vapor/smoke since this is a sign of incomplete combustion.  If you add air above or right at these smoking points then flame will "advance" into the smoke area of the log and finish combustion.

Dry or seasoned wood doesn't have this issue as much since the water content is low and combustion continues whether in excess oxygen or even starved of oxygen.  This answers your OTHER question, if an area of seasoned wood is starved of oxygen then you are basically making Coke from your wood.  That's why when you open up the flue and get air moving again, any residual embers will light up the coke in the pile quickly.

Anyways Dave,  I'm disappointed in you for not being actually concerned with truth when you go all soapbox about it. There's a reason fundamentalist Christians are so reviled by the rest of us. Your ethics are disturbing. You lie to yourselves and to those around you and want to tell other people what to believe based on only your assertions. Well, your assertions are retarded and your lies in their service would only be funny if they weren't so damaging to humanity.

Fundy Christians. Can't live with 'em, can't feed 'em to the lions anymore.
You're an idiot.  Of course I'm concerned with truth.  And one of the biggest truths around is ... there was a Global Flood.

The only truthful comment in your reply is calling Testy an idiot.  Which, IIRC, Testy holds as a badge of honor.

Otherwise, your hypothesis of a Global Flood as described in the christian bible has no evidence to support the story.  Everywhere we look in detail the evidence is lacking.
Geology?  No direct evidence of a global flood in any layer when examined.
Radiocarbon Dating?  The Global Flood's worst enemy.
Archeology?  No flooding noted in any find.
Geography?  No flooding results that are not BETTER explained by other phenomena; and definately no global impact noted.
Physics? Nope.

So all this trope of "LOOK AT THE BOOOOONNNNEEESSS!!!" is just that.  Trope.  You need not ONLY evidence but a preponderance of evidence to make such a bold claim as a Global Flood 5,000 years ago.

Doobie,  I hope you threw out your laptop after searching/copying these items.

Although I did learn today that Extinct Dinosaur beast porn-sex is a thing; I didn't really want to know that now that I'm faced with it.

Science / Re: Neutron star collision detected

Hahaa, I remember a guy in high school who thought "eyebeams" were a thing.  He asked the teacher, "Mr. Jehlik, when you look up at something, how fast does that go?".  Mr. Jehlik explained that the light was entering your eye the instant you look in that direction.

I had quite a time getting a friend of mine to "visualize" the concept that he wasn't actually seeing me directly but his brain was detecting what bounced off of me and that was just the stuff my body and clothing didn't absorb, colors, etc.

TBF, we were pretty "lit" at the time but once I turned the lights in the garage off while taking another explanatory tack, the "lights went on" so to speak. It was a pretty cool moment actually. Went on to talk about color shifting in soap bubbles and other mediums, refraction, and stuff like redshift. I miss those days.
This is how they should teach physics classes.  Now that states are MJ legal ...

"drier wood"

Yeah I'm not too good about this ... I need to do a better job keeping it dry.  What about wood species?  Hedge is my favorite but I don't have much.  I have a lot of hackberry and oak and elm.

Dry is the important thing.  The next most important thing is sustainability - what have you got, and how much can you coppice of each species sustainably?
