Hug,  no flour of any kind?
That sounds good...
Now I'm wondering if I'm confusing a crisp with a Brown Betty...

So we are selling baked goods at the farmers market.
We've noticed a demand for gluten free sweets, and we have access to fruit at good prices, so we thought an crisp might be good.

A quick look on line offered a plethora of choices, but what source can I trust?
Hmm,  what place do I trust online...

So I'm asking y'all , what do yeah got?

Apartments built inside of the barn is the way I would go.
How many families are you thinking of?
How big are the families?

Very cool stuff.
I love wicking beds and sub irrigated planters and this is like those on a grand scale.
One could potentially cover most of a ponds surface with these rafts,  preserving the water from evaporation or freezing.
I wonder if azolle ferns would add nitrogen to the water?
Even if not, they could be a ready at hand high nitrogen mulch for the rafts.

How about placing chicken wire down over the roots?
Of course stopping the chickens from scratching might keep the larva safe.

What if you caught the falling nuts in window screen nets?
Collect them all,soak them,   crush them, heat them,feed them to the chooks.
No insects larva reaches the soil, the chooks stay out of the hazel roots , and you still break the reproduction cycle.

I would be inclined to let the chickens have at it.
I have heard that hazels are quite resilient.
If the hazels can't deal, maybe they aren't tough enough for permaculture?
Are there other plants can deal with chicken around their roots?
Are there pest resistant hazels?

I have a laundry to landscape system on my back porch.
It drains through a mulch filter and waters the mulberry tree and grape vines.
It's half a IBC full of mulch and filthy water comes out clear on the other side.
If I ever make a kitchen system,  I'll send it through the same filter.

Raccoons...
Cute, as long as you don't have anything they want!

Can they fit through chainlink fencing?
If not,  I find used chainlink to be relatively easy to aquire.
If it's set far enough away  they won't be able to even reach the chicken wire to tear it,  and the ducks won't be able to wander into their clutches.

Wow 275 is huge,  I was thinking 40 to 80 gallons.
I think you probably lost a lot of heat to the air, even small batch box stores are known to boil gallons of water  rather quickly.
Peter van den Berg  calculates the btus per hour of a 6" batch box to be about 77323 in the following thread:

https://permies.com/t/57202/BTU-hr-Batch-Box-Rocket#:~:text=Lower%20heating%20value%20efficiency%20is,yield%20about%2077323%20btu%2Fhr.

That was 2016,he might have changed those calculations since then.

If you enclosed the heat exchanger, be it a coil or a tank, inside of a bell,  you will increase the time the exhaust is in contact with it and that should improve heat transfer.

Most wood boilers seem to use a water jacketed firebox,  but that's not good for rocket stoves.
A water jacketed barrel enclosing the riser would be great,  but could require advanced fabrication.
I have successfully created a water jacketed feed tube with a steel inner cylinder ,  terra cotta outer cylinder with cement and silicon caulk in between.
Since tempatures never rise above 212F,  regular silicon caulk and cement work fine.
Scaling up, a  55 gallon barrel could serve as an outer cylinder, a 30 gallon drum(or 40 gallon water heater)  as the inner.

Stainless steel cooking gear is relatively cheap, heat resistant and has good heat transferring properties.
Steam table pans,  giant mixing bowls, stock pots and bain maries all have potential as parts of a heat exchanger.

I would build the biggest batch box you can.

J tubes are less efficient and take more tending.
They also need a longer heat riser to be effective, and just as much insulation.
Most advocates for the J will say it takes less skill to use,  but they also recommend building them in a  location that is in the center of family life.

I would not build a coil,  rather I would use a directly heated tank that was connected to my giant storage tanks.
The steel tank from a gas water heater can be had for free.
I would use this instead of a coil so I could avoid finessing the size /safety factor and to save money.
It would be unpressurized of course.

Nice diagram Mike!
I was thinking that insulating the foundation and wall would require lots of digging.
Would you suggest  a horizontal apron of insulation around the foundation as well as the wall?
