  • But, as far as I remember, major contributor to carbon emissions are not poor villages, but jet sets and their factories in poor villages exploiting the work of poor villagers who have no say about their air quality lest they lose their jobs like they lost their means to sustain themselves from farming. Indeed, just not flying for fun and not selling the oil and coal that do not really belong to them would be so much more technological than trying to get grants for things they do not understand (and waste them traveling the world on planes telling everyone they should invest in it too only to then burn the rest in taxes used to support oilgascoal industry directly or not). When you show perpetum mobile here it is totally relevant - that’s how greenwashing works in terms of economy on every level, no matter what technology is being praised.

    That’s essentially how many gases are made from mixtures, like notrogen or oxygen. Showing this as something new tells a lot about author’s uderstanding. Carbon capture is not about making entirely new tech, it’s optimization, and that’s where startups suck at everything except for getting and then wasting cash.



  • Malting it for base malt is probably not worth the effort indeed (kind of weird that there are a few small-scale enterprises around where I live who try to make small batches of malt - and it’s base malt. Of course it’s inferior to large scale, sadly, I had sad experience trying to use super-local. Why don’t they see the real market potential for weird stuff? Maybe I should take that space when I set the process?), but there are limitless potential specialty varieties you can try. Roast it differently? Skip toasting altogether and use it asap to see what happens? Reproduce some historical process? So much fun (probably).



  • I have similar situation (but right now I have ~20 kg of oats, there are other stuffs around too, I just happened to take oats), so I’m trying to build some decent malting equipment. Unfortunately, doing it outdoors in winter is sad enterprise, but I’m totally just giving it a try when I can! (Doing it indoors would be either stinky or loud, and I already have too many microbiological stuff going in same space) I do not believe I’ll lose much except for conversion rate and sugar content, but might discover some new flavor tones. When I’m done, I’ll be posting here and trying to share the product.

    So I urge you to do the same!

    There is no reason to expect that something will not ferment well just because it was not purebred for brewing. Even random yeasts mostly yield good results. Well, yeast is much more definitive in final profile and you CAN screw up by using some really stinky or low fermenting yeast. Grain, on the other hand, is just yeast food and grain flavour mostly (yes, there are other things to fine tune, but first order approximations is what we should care about in experimentation). Does it smell and taste good? Then go for it!


  • Just to be safe you might consider replasing chloride with sulfate.

    Sure this is great way to make thermite or anything that does not exactly care about oxidation state, that part I can confirm.

    Furthermore, you are close to iron(6) synthesis here using drain cleaner. Yield would be even lower, but fun is worth it. Be careful though, when literature states it blows up, they mean it.





  • Well, it’s bad news, all those super-processed products almost always are treated with metabisulfite or something close enough, and only wine and a few other products require it to be listed on the label. It’s pretty much treated as part of detergent for washing fruits. Completely unjustified as product is sterilized later in turning it into extract, but it is simpler to keep buying this historically accepted mild bleach and treating all fruits with it anyway. Maybe increases their storage time in shipping pipeline. Something I do not wish to think about in great detail, for my first lab in Finland was in a rented fruit storage bunker and I washed it and dismantled control equipment myself. Could have been WW2 nazi camp facility for what it was worth.


  • In my childhood, we had these kinds of root vegetables sliced and caved in on one end, and a spoonful of honey was placed on top and in the cavity. Somehow this sped up conversion to overnight, and it was a treat. I guess, similar process could be used to convert them for brewing.

    Although the whole idea sounds a bit like potato for vodka. Nothing wrong with that too, but the flavor might me less than interesting in the end. Worth trying I guess. I wish I had some of those now, not unripe ones from the store.


  • One of the biggest suspects in this cyser story is metabisulfite treatment that might have happened to apples. I do not know the exact mechanism, but lots of people complained about headache if that was used with apples (and many recipes call for its use, IMO totally unjustified) or in apple juice in factory. Same thing about grapes. Differential is quite clear.


  • Steamings damage corks, especially sterilizing ones. Their number should be minimized. Now for bottling, I do not think it is important for corks to be sterile, as anything worth of corking will kill whatever might be living on cork surface. Sanitized is enough.

    Now repackaging is another beast. Once packaged, corks are left for indefinite time, and if inoculated with something that might survive on bare cork (pretty much this means fungi), it might become a nice growth media. Then, steaming might kill it (and if it is not pressurized, that would not kill spores), but it will not clean it from the cork.

    So, on small scale, it is not very important, some corks might get spoiled occasionally. But 6000 is no small scale lol.




  • Only proper wine corks are good for proper mead. I mean, yeah, there is place in our life for fermented honey solution that is consumed fast, but proper mead should age like expensive wine. It’s more noble than wine, after all!

    Bottling mead thus is always a challenge. I’ve tried all kinds of methods, or course beer caps - and especially swingtops - just start leaking at best in few years. Compouns corks too, and, being low grade stuff, they are often stinky themselves. The only exception are belge bottles and fat compound corks for braggots, if corked belge way, they occasionally leak some liquid at first, but then seal themselves for good.

    Even higher grade corks tend to degrade over the years. Highest grade does not degrade. I’ve just negotiated a sample of fancy corks from Portugal, about 1eur/cork, highest grade. They look really good and will probably work, but min order is 6000 and they have to be repackaged sterile. Good thung I have sterile line, but 6000? It’s 10x more than all bottles I have now! I could place them in my webstore in small bags? Would someone be buying them?

    I was looking into alternatives, but nothing so far looks promising. I’m thinking about turning other wood types on a lathe, but that will probably result in a disaster.


  • So ok, these are just quasiparticles. Yes, we could have quasiparticles that behave like actual particles. Yes, it’s just an abstraction. Yes, we can go batshit crazy in abstraction space and come up with anything.

    This reminds me how some folks in ScientificAmerican modeled black hole with a vortex in water and found supersonic wave, which brought them to conclusions about possibility of passing through event horizon in actual black hole. bah.

    In other words, when do I get some money to build a quantum quasiparticle computer and finally hack elliptic cryptography?

    Though, as Rice alumni, can’t deny still always awesome publicity of that university.
