Very cool stuff. I might have to look a bit more into this. There’s a chap melting copper here with a 13 square foot lens - looks like a pretty small beam, not sure if usable for your purposes. But cool idea, have you got some lens dimensions in mind?
Also, definitely not guaranteeing any safety, but think i’ll give it a shot.
I think I’ll see what I can do with this, Does something like this look suitable? From my back-of-envelope calculations, this gives 17000N force (about 1750kg-force like they’ve said).
And then the challenge is to release the pellet, and refill from a hopper containing more biomass material. Can you tell me what biomass material you would be using?
Any material, the software i’ll be using has some basic material properties built-in, but theres room for customisation.
Size limitations - any sort of dimensions. Complexity - i could probably do a few mechanisms that are less than maybe 5-10 parts. Or else one large, say less than 50.

That sounds great! I hadn’t even considered capturing human waste. Do you rely on that entirely? or are you hooked into the mains?
A potential solution could be having a larger central community plant taking the scraps from several households. But again it won’t be enough to provide cooking power for all, maybe it could give back some other type of community benefit.
Spitballing here but that slurry could go to community gardens.
I’ve looked at these before, really cool idea. I think one issue is the amount of waste needed. How does the author get 2kg a day? I reckon my house (of 4 people) chuck about 4kg a week into the compost.
A good way to supplement it would be with yer chook droppings, but still not enough to cook for a household.
Sure, I’ll work off that copper coin lad’s dimensions and try and make it adjustable like the smelter. Could you point me towards an example of the little coffee can forge?
