Only I would expect the design would not be 3 dimensions as you asked but mostly all forces in one plane 😁

A cool. That is a known wide spread design. This is a very high force, I’m impressed. But it will come at a cost of displacement correct? We aim to make brickets for cooking fuels and we have a lot of groundnut shells. These groundnut or peanut shells have a a lot lignin so it is possible with wetted mass (softening)and perhaps heating with fire (lignine becomes like a glue at 200degC). After that the brickets are sundried. The bricket shape could be like icehocky pucks or at least the shape to cook with.

I think the wooden design is not that interesting to generate, but with a pellet release and refilling in one lever go (or two steps). That would be an interesting puzzle, yes?

I follow this person already for a while, very interesting things he come up with

For work in Malawi I am thinking of introducing a bricket press to make brickets from biomass. One person must pull a lever and a piston is pressing biomass into a cylinder and compresses it. The end of the stroke should be stronger and less fast. And with returning of the lever the pressed bricket or pellet is pushed out and new biomass is inserted. It can be an interesting design from scratch and nice context? It would be challenging to make it convenient for the person while large pressing forces are reached (5000n)

You are right, of course. Also repetitive thermal expansion comes into play here. We can compare it with repairing a broken heating element or other single part, instead of replacing it. My patience to properly glue it was also part of failure, hehe.

I tried the same with a low cost grill iron ( to make sandwiches 🥪). With back in my mind that I not would buy another one but fix this one once it should break. The hinge broke and a few tabs that hold oneside metal in place. I glued it but after two weeks the it broke on another place. Could not live without tosties, have now a newer bigger one…I’ve tried…

Indeed, the man is painting the grass green.

Unfortunately that would negate the high storage temperature of sand (up to 800 degree c) as water will turn into steam after 100deg. So it is either low temperature sand or water with lower energy density.

I like aluminium powder idea. And use the metal bar as heatpipe is a good idea. I would not see temperature as problem as most materials you mention can handle 800 deg. The idea is that you can draw energy from it thus cooling it. I think a molten salt chamber uses this combination of fast transfer and high temperature

It is an interesting these technologies you compare. Yes, a sand battery is in potential capable of storing higher temperatures if the source can generate these temperatures. We also have to look at the heat transfer that will seperate both energy buffers if seen from an application point of view. The heat transfer in sand is very low and this intrinsic insulation of sand begins to be very interesting when larger volumes are used. Water has a problem that it needs an extra insulation layer and larger volumes would be less interesting in comparison. However water is faster in exchange and is interesting as smaller buffer with shorter bursts and intake of heat.

Also if these are not load bearing beams ( they have been almost cut throughto allow the pipe going through), make the gap wider and put some isolation around the pipe. But only if the pipe is the case of the water problem

Ah I see now there is double thread 😶‍🌫️

Nice to see another project of you. I’ll post my chicken coop project in near future as well

Very interesting read. Time to make these sensory excursions open for public to understand the clouds physical existence.

The summary pictures below

Nice to see / read. The super glue trick is nice to know. I also wanted to mention that the collection of pictures on the bottom is broken when you open them on movim.slrpnk.net

Well, bad for you if it is a crappy option. The company doesn’t care for quality as the consumer has no other option. Hurray for Amazon, our everyday feeder. And for those working at Amazon, only one toilet break per week, as there are no other options for work!

Good job @hamtron5000, you need to place the cats somewhere 😁. We also built a cat collector last month. The trick with us was the stovepipe that did not allow combustables nearby so the pathway is very small for the cats
