Yes, and this is the principle behind the rocket mass heater. It basically takes a very hot fire's smoke and sends it through a long duct inside something with a large thermal mass.

Almost all of the thermal energy is absorbed, but the draft from the hot fire at the other end pushes it through the system.

How did you even know about this? Are you really 1/8th divine?

You know how some dads have a stack of Playboys in the back of their closets?

My dad had a stack of Mother Earth News.

Cool. You're lucky-- when I stumbled across my dad's stash of VHS porn, I accidentally discovered why my mother was so popular back in the day. Dammit, thanks for bringing up that repressed memory!

Consider yourself semi-hemi-demi blessed

Do these ad together or continually divide?

I just thought you were kind of a Mopar guy.

....source?

I stg, my dad didn't even bother hiding his porn discs, like he wanted me to find them or some shit lol. I was around 13 or 14. Just threw this out there cause it's half relevant, or you could even say it's semi relevant.

Mine did too, but he picked the wrong magazines.

He probably did want you to find them. My dad would do devious shit like that. Leave something out in the open, but note its literal exact position, so he could find out if we touched shit we shouldn't have.

What is your mothers name? Were you born during a leap year perhaps?

So you don't really know who your real dad is?

My dad had a stack of Mother Earth News.

I'm so jealous.

He got rid of them, but not until my mom bought their entire back catalog on DVD to replace it.

Lucky. I only built a solar hot dog cooker before my inherited Mother Earth News collection got lost in a flood. I remember dad grumbling when they went to glossy still drawn covers.

I'd be disappointed if the Hedge POrn Fairy left Mother Earth News in my local park

This is so wholesome

"grow your own luffa sponges"

I don't know why I find that so funny.

It was in a pretty popular reddit post like a week ago.

Some people on reddit love it and will not shut up about it

Damn building one just went on my bucket list. That's very cool

Yeah, speaking of which, I wanna build a satellite before I die.

Everything is a satellite if you yeet it hard enough

Just make sure it misses the planet (and preferably the atmosphere) as it 'falls' back down!

And that's an ELI5 for how orbits work, you're welcome.

Hey, sometimes we want decaying orbits.

Nobody said "earth orbit" Major Smartypants. Gonna take a helluva yeet to get that baby out of Sag A's orbital plane.

And a row boat!

I looked into building one at my house but the building inspector said it would never be up to code.

And that's the problem with code, the rules on the books have a very limited imagination. I'm not an anti-code guy (I'm a firefighter so I know how quickly shit goes sideways when things are built unsafe), but there are tons of energy saving things that can be done safely that aren't allowed because "well...its not on my rule book".

There is an ice hotel in a place called Chena Hotsprings. It is literally a gymanism size building constructed out of ice. You can rent rooms there to hang out in, and party in, and fuck in. But you can't legally sleep there because it doesn't have a fire sprinkler system. Yes, the ICE hotel- that has ICE walls and beds and tables doesn't pass fire code.

Often they’re not allowed because usually wood burning stoves have terrible emissions. But this one burns very clean because it burns so hot. Still not allowed.

But I’d just build it and say it’s an art installation and not a stove. I have weird taste.

Nice read, thanks for sharing!

Well I learned something new today. I was under the impression they burned so hot they didn’t create smoke or very little. That may sound stupid but I don’t know shit about fires or stoves for that matter except how to start a campfire.
