  • Ah my bias: I was only interested in grain mashes. My immediate reaction was, “why on earth would there be wood in your mash?” The answer is fruit stems. Methanol will be differentially in the foreshot but if you’re not expecting much because you’re not fermenting any wood, it’s going to be low in the foreshots and very low in the hearts, but not much anywhere. BUT if you’re fermenting something with woody stems, I can see that methanol removal is going to be worthy of consideration.



  • one purpose of distillation is separating them

    The purpose of distillation in this context is ethanol concentration. Methanol separation is possible but not really the goal.

    Thats why you have to remove the foreshot

    I don’t think the foreshots have a particularly higher concentration of methanol, other nasty stuff sure, but I think methanol is in pretty similar concentration to the ethanol.

    An incompetent distiller can still cost you your eyesight or even life.

    My understanding is that it’s people cutting the ethanol with industrial intoxicants that gets people injured/ killed. Ie people recklessly adulturing the alcohol.

    The only problem I’ve heard of that’s from distilling itself and not intentional contamination is people doing freeze distillation of ciders (skin on).

    That said, most of my reading has been with respect to pot stills and grain beers, maybe fermenting fruits create more methanol than grains, I still think intentional contamination with who knows what is higher on the risk list than accidentally high methanol concentrations. But if you know of specific cases I’d be happy to read them.


  • Edit: my view has been substantially altered. Due to my existing bias towards all grain mash, I hadn’t considered the possibility of woody material fermentation on methanol creation. I still believe negligent adulteration is more of a risk than negligent distillation, but negligent distillation is not a totally irrelevant risk.

    My investigations into home distilling convinced me that distillation doesn’t convert ethanol into methanol. Moonshine poisoning is the result of adulteration of the product, (mixing it with other intoxicants) not bad distillation.

    Basically sometimes people put other stuff in moonshine to reduce their costs, or give a special buzz. There’s no guarantee that the adulterant to be concerned about is methanol.












  • Edit to add disclaimer: this is shitpost level math here guys, I’m just spitballing.

    It would definitely emit thermal radiation. if it was 99% efficient and the size of pluto’s orbit, around a star like the sun, and the energy was used to create matter, I think it would radiate the remaining energy as 0.009 W/m2 with a peak emission wavelength of 150micrometers. The James Webb telescope has infrared capabilities that max out at 28.5 micrometers so def not detectable.

    But probably a dyson sphere would be smaller than pluto’s orbit, which would greatly increase the apparent power, and shorten the wavelength. idk it’s all imaginary.

    I won’t subject you to my hand writing but I did (power of sun × 0.01)/(surface area of sphere with Pluto’s orbital radius) to get radiation intensity (0.009 W/m2). Then rearranged Stefan-Boltzmann law to solve for temperature (19.8K). Then used Wien’s Displacement Law to calculate the peak wavelength (1.5×10-4 m).

    Maybe I’ll run the numbers again with a martian orbit radius, and 50% efficiency.

    I successfully submitted for a short term disability claim for an anxiety condition that arose from my ADHD. A few weeks later I was told that there wouldn’t be a role for me to return to once I was recovered. IE in an attempt to avoid a nasty law suit they aren’t firing me until I’m off short term disability.

    Talk about setting up adverse conditions for recovery!


  • I was pretty skeptical of them when I clicked “Technology Connections” video on them. It’s the same thing as a convection oven, what’s the big deal?

    Well it’s the same just like how a quadcopter drone is the same thing as a RC dual rotor helicopter

    It’s like yeah they’re the same thing, but they have some important differences too.
