Well sure, but then you'd be in Cibola County, NM. After driving for an hour, you're still an hour away from civilization.

"hydronic" is the new geothermal. You can use the constantly-55 water as your thermal mass for a heat pump. You can pump heat out of the 55-degree water and put that heat in your space, and vice versa. It lets you have an arbitrary temperature inside your dwelling. You just have to size your hydronic field so that it can absorb the heat changes, either warming up or cooling down before that well is needed again.

Ry the drop ceiling fire baffle to compensate the open flame basically turns your entire home into a giant wood burning stove.. Big Hansel and Gretel vibes. I hate to go on about it but it's literally a recognised suicide method to light a charcoal barbeque in your car.

I can't speak for the quality of this product but there exist a few stoves specifically for using inside tents, usually semipermanent like yurts or bell tents. What about a canvas tent or awning that folds out above and locks I to placeover the Murphy Porch?

Also if you are still planning on driving the box truck you really don't want an open bucket of ash getting shaken around in your sleeping quarters.

We will see how it goes first. I like to see something fail at least once before ruling it out.

The stovey thing looks cool, has an open grill thing which is kinda what I'm wanting, but only three legs?

As for the bucket of ash it would be outside my sleeping quarters and of course I'd dump the ash.

Yeah earthships are pretty cool. One issue with them that people don't realize is that in an earthship or any building that has a major geothermal component, is that geothermal unless you're near a volcano or particularly radioactive land usually only maintains a temperature of 55 degrees which some people are unaccustomed to living at that temperature in their leisure. Living in GroverTruk for a while, anything above 50 degrees actually feel acceptable to me now that I've adapted to it.

State code however mandates that interiors of living spaces are to be heatable to 68 degrees under winter conditions when measured a foot from a wall and 3 feet up from the floor. So geothermal isn't really allowed as a stand alone in my state.

When you say radioactive, what do you mean?

Earthships are a really cool idea, are they practical in temperate climates? I usually only see them in high desserts.

There's pretty significant variations in how radioactive soil is, mostly on the basis of its potassium, radium, uranium, and thorium concentrations. Pitchblende is an example of a pretty famously radioactive ore, since it's the one that Curie used to isolate radium.


I'm fuckin losing it

Yeah, but how would that correlate with geothermal heating?

Well, if you have enough radioactivity in the soil, it could locally raise the temperature.

Not so much that it would differ by more than a degree or so vs the rest of the continental shield temperature, but hey, your muderhaus is now at fifty SIX degrees.

Rytheric, fold out your murphey time machine and get some radiothermal heating.

No way.

Specific heat capacity of dry soil is 800 joules/kg

1 Joule=6.242x10^12 MeV

The most energetic decay of Radium is about 14 MeV

1 decay/sec= 1 Bq of activity

So we need about 5x10^15 total decays to heat 1 kg of soil 1 degree C

Spread that over the course of a day, or 86,400 seconds and that's 5.8x10^10 Bq/kg of activity, for reference the average concentration of radionuclides earth wide is about 500 Bq from all sources, the worst contaminated areas of the Nevada test sites are about 3.7x10^6 Bq/kg of Plutonium.

370 Bq/kg yields about 1mSv of radiation 1 Meter above the ground, so 5.8x10^10 Bq/kg would yield about 1.6x10^6 Sv of radiation exposure 1M above ground, so this level of radioactivity would yield about 100,000 times the lethal dose in an hour.

I'm sure my math's incomplete, not taking into account all radionuclides and whatnot, but I'm pretty sure it's not 6 orders of magnitude off, and there's almost nowhere on earth that is radioactive enough to be substantially warmer than nearby areas simply from alpha decay, I know deeper in the earth's crust and in the core is a different story, and I'd love for someone to prove me wrong, but as someone that deals with heat produced from radioactive decay professionally, activity levels high enough to produce enough sensible heat to be useful for geothermal heating doesn't pass the sniff test. The only articles I can find about geothermal heating are in the same vein as this IAEA article talking about radionuclide residues from deep geothermal wells.


Weird poo poo like the Gabon Reactor/Arc of the Covenant not withstanding

E: looks like 2g/Kg of Pu238 typically used in RTGs could do it, with reasonable radiation exposure, but that's a man-made isotope.

I found a paper from the Colorado School of Mines where they flew an airplane over known uranium deposits and open-pit uranium mines and the earth there was about 1°K warmer. So, stuff is going on with nuclear decay, but probably not enough to heat your house with unless you're camped directly on top of a huge pile of yellowcake.

So yeah, you already plan on not having a back door on the thing, so why would including a murphy fire pit indicate that you need to close the porch when you go to bed?

As far as the levelling goes, I think there is another solution besides the singular and very specific one you're currently envisioning. Note: I think this goes for pretty much every item in every post of yours.

I may not know a ton of geology, but I know enough to know that there aren't buried mineral deposits that will make a thermometer read 1 degree celsius warmer when there's hundreds of feet of air between the thermometer and the mineral deposit. I may be wrong, but I feel like no one would bother using expensive gamma ray spectrometers to find radioactive mineral deposits if a thermometer would do the job just as well

Also, the amount of radiation that would make a thermometer in a plane read a full degree higher than the surrounding areas would kill a person so quickly that humans wouldn't be able to set foot on the mineral deposits, let alone mine it. Just think about the scale of things for a minute, you'd need exposed minerals as ridiculously dangerous as Corium to be radioactive enough to heat the surrounding air hot enough to read it from a plane, and exposure to hot corium is lethal within minutes

However, this would imply that if I ever wanted to access the back without entering through the cab I would have to have space to lay down the Murphy porch. I believe a pull out porch would probably be more suitable, but then I'd be exposed to the sun without an awning. And I may be too lazy to pull it out one day.

My understanding is that most of geothermal heat is the result of radioactive decay. Why would the ground that has never been heated up by the sun be warmer than the surface above if there isnt a heat input.

Pigsfeet on Rye posted:

So an idea just occurred to me, hopefully I didn't miss anyone else putting this out:
You install a Murphy porch, solid wood throughout, on the back of the Grovertruk so that when it swings up, it acts as a door. You make it large enough that you can put just a thin (1/2" or so) piece of compliant foam around the interior of the truk and the foam will assure a weathertight seal against cold, elements, insects, etc. You start out with a long metal arm (also called a fireplace crane, the kind of thing that people would use to hang kettles in a fireplace in long ago times) kinda like like this () whose length is the same as the complete width of the truk, attach it with heavy hinges to one side of the door opening. The hinges should be designed such that they have holes that pins can go through to hold the arm at a particular angle, maybe 90 degrees (parallel to the length of the truk), 45 degrees, 30 degrees, and 0 degrees (parallel to the width of the truk). The other end (the tip) of the crane arm can be bent and drilled into a hasp so it could mate up to a staple installed on the truk; when not in use holding a firepit, the crane arm can act as a locking mechanism in the 0 degree position (with a padlock) to keep the murphy porch securely closed, giving you some amount of safety and protection. On the crane arm, you suspend a metal firepit with a metal handle or chain (), locking the crane arm at one of the intermediate positions. You can slide the hanging firepit along the length of the crane arm to position it correctly. At night, you lock the crane arm out at the 90 degree position and hang the hot firepit at the very end with a perforated metal screen over it, that way it can burn itself out safely.
Stay safe

Rytheric posted:

So I get the crane idea. But the swinging open murphy door I do not unless I'm able to swing it open from side to side like you're suggesting like a door then rotated it and level it with the ground. This sounds a bit more than I'm willing to do. I'm thinking I could just put a small square of plywood on hinges on the floor and flip it over and brace it against the metal bumper step to have the fire stick out alittle from under the cieling if it's a problem. That way I can still use my steps while the fire is deployed and the fire be outside and the whole flippy thing doesn't take up room.

Pigsfeet on Rye posted:

Could be that I misinterpreted the whole murphy porch thing. A murphy bed, as you may know, is hinged at the bottom so it flips down from vertical (storage) to horizontal (usage) thus:

I had thought that, flipped into the vertical position, it would act as a door; flipped into a horizontal position, it would act as an extended floor / porch. You could have some hinged or detachable steps to mount on the side of the murphy porch to allow you to step up or down to the ground.
