I'm not sure aluminum leaching is really anything to worry about, but if it worries you, a silicon bunt cake might fit this oven fairly closely.
A steel bunt cake pan might even be used as part of a diy version of this stove top oven.

I see that the tea light didn't work, but I bet a twig or pellet burning gasifier stove would work great.
They can be easily made from a stainless steel double walled vacuum insulated  drinking cup/water bottle.

A tiny alcohol or oil stove also might work.
Imagine burning  tallow in a little stove and the hot exhaust  flavoring your biscuits

I propagate plants because I'm compelled to.
I work a job to pay for life.
Propagating as a hobby could pay, but that will happen as an outgrowth of me getting more and more skilled at it.

Get paid fixing appliances, build your nursery on the side
Focus on permaculture plants and  other hard to get items to avoid the competition.

Electrical storage heaters  heat ceramic bricks during times of day when electricity is cheapest:

This is old tech.
Coupling it with PV solar is old tech
The difference is a rocket stove heats through radiation and a storage heater will often have ducts and fans as well.

So yes, it would work, but I doubt it will work as easily as we might hope.
For example, most electric water heaters in the US use 120vac.
Most ovens in the US use 240vac.
The water heater thermostatic switch will probably not work well with coils from an oven.
Of course ovens come with their own, so we could salvage that.
Also you could use probably two of them(I think water heaters generally have two) and switch each leg of the 240V circuit.
We can install the coil in the base of our bell and the thermostatic switch into the wall of the bell.
Hmm, the inside if a rocket mass heater bell is way hotter than
The inside of an oven or the skin of a water heater.
No matter, we will either embed the coil and thermostatic switches in the walls to protect them , or get higher rated components off of the Internet.

Now to power the thing.
I would assume we would wire it into mains power, since solar produces DC voltage and we need to rectify that over to AC voltage for the sake of the components we are using.
There will be loss, but we are talking about storing otherwise wasted energy, so it's not really a big deal.
PV solar often uses water heaters as dump loads, so I imagine there are off the shelf solutions we can use to ensure we only fire up the up the coil when we have excess solar pv.

 This seems like good idea, the suggestion I would make is to plant perennials as well.
What fruit grows well in the heat of a Missouri summer?
How about figs?

Of course a trellis with vining plants might work as well.
I grow a grape vine on a wire cable to provide shade for the Western wall of my house.
No grapes, just lots of leaves that grow in right when we need them.

I am planting some sunchokes in buckets, and placing them front of a community garden greenhouse , with the idea that they will provide shade,biomass for compost, food and nursery stock.
I plan on adding favas to the buckets, and maybe some elderberry cuttings.
My only concern is high winds, but we will figure that out.

To me the point of kilning fire wood is to save time.
For example,in the case of a collapse, green wood will be immediately available but seasoned wood will be at a premium.


One YouTuber I've seen uses a sawdust stove to dry sawdust bricketts for sale and use.
Another drys firewood in the same shed that houses his forced air wood furnace.
As long as you are using otherwise wasted heat, drying fuel seems viable.
Burning scraps, sawdust or whatever just to dry fuel  is more iffy.

My personal preoccupation with making use of the heat from charcoal production is why I am curious about wood kilning.
As seen by the responses, drying fuel with incidental heat is very popular.
I think certified kiln dried firewood can cross state lines and this be sold at a premium.
There are other reasons besides fuel drying to have large oven that can get up to moderate temperatures.
Dehydrating of human foods or animal fodder, steaming of building materials, even cloths drying , maybe.
I think a white oven is probably the way to go for any of these uses.

A black oven is a wood fired oven where the combustion gasses passes through the cooking chamber.
By the contrast,in a  white oven the combustion glasses heat the cooking chamber from outside of the chamber.
Wood kilns need venting to remove the water vapor that is exuded during baking, which is why I thought a black oven might be good.

Too much heat will torrify , then pyrolize the wood.
That would indeed reduce the fuel value of the wood.
I've looked into it a little and most wood combustion will have water in the exhaust, so a black oven might be counterproductive?

Kilning firewood can improve how well it burns.
It can even season green wood in a fraction of the normal time.
I've watched a few videos on the process that have me wondering, could you build a "black" oven to kiln dry the wood in?
I can see it being too hot, too fast, leading to case hardening of the wood.
That could be addressed with a bigger oven and a smaller fire.

Here's a nice first hand account on using this plant,complete with nice photographs:

I totally understand using nice new materials for other people's raised beds!
I use cedar dogeared pickets measuring 6'x5.5"x 0.5" , as the boards for these projects.
It's hard to join two 1/2" boards neatly and securely without involving  a 2x2 or 2x4 .
I haven't found any cheap, durable non-toxic 2x materials.
I have ripped cedar boards in thirds and then sistered the results together, but I suck at carpentry and safely ripping  narrow strips of wood is difficult for me.
Going forward I will be trying steel framing brackets for joining these thin boards at corners and mending plates for joining them end to end.

If you are willing to use cardboard, that is the easy route.
The forever chemicals found in cardboard would probably stop me from going that route.
Hardboard is a wood based sheet good that is created without glues.
It's the same material pegboard is made of.
I have used in direct contact with soil, where it lasts for years of use.
As a liner for a bed, it should last a long time.
