Soy or Rice Stove, etc?

With a likely continuing excess of some foods (and animal feeds) in some places, I thought about what could be done with those instead of leaving them to rot like they did during the height of the pandemic. I haven't found much. While there are some grain burning stoves besides corn (wheat, rye), I found none for rice.

I did find an out of stock multifuel soybean stove. Would oil extraction (biodiesel, oil burning) followed by soy pellets be more useful?

Other Surpluses?
Are there other resources that might go to waste and could be used for unusual purposes (not just fuel)?

Responsive Companies?
Do you know any companies that could be interested, if made aware, in modifying their products to use the above fuels and more?

Burning corn in wood pellet stoves is fairly common.
Rice hull stoves are a thing, mostly they are TLUDs or gasifiers.
I think pretty much any design that burns wood pellets would work with seed foods.

I am intrigued at the idea of burning tree seeds rather than food seeds.
Trees like black locust or Kentucky coffee bean, make a lot of seeds and fix their own nitrogen.
Still, having the option to burn seed foods in an emergency  is no bad thing.
A bag of corn could do double duty as emergency rations and fuel.
