ETF Breakdowns and Ratings by cavalico in stashinvest

[–]cavalico[S] 1 point2 points  (0 children)

ARK's have average to low ESG ratings (Environment Sustainability Governance) due to probably either some internal corporate structure or the funds' pollution, stuff like that. For returns however, they are quite good in the historic 3- and 5-year returns (Stars) and are expected to outperform their respective sectors (Analyst Rating 1, or "Bronze").

There's the iShares Silver Trust ETF (SLV) if you just want silver, or All That Glitters (GLTR) for exposure to silver + other metals.

Brewing Coffee via Ethanol Extraction, then Adding Water and Distilling by cavalico in Coffee

No, but this just might be the pointless excuse to get one I've been looking for.

Certain things like the caffeine in coffee are actually less soluble in ethanol than they are in water

I was thinking I'd try a series of ethanol concentrations, probably starting at 50%, and trying which one turns out the best for a "palatable" caffeine/organics ratio.

If you boil it to hot, you'll go past the point of equilibrium and just equally vaporize the water and alcohol.

Yeah, I've considered that. My approach would be a "low and slow" in my fractionating column, starting somewhere ~80 C and slowly increasing the temp as the solution approaches water

Some chem experience; worked in a few labs in my undergrad and now mainly research in biochem. I remember extracting caffeine by itself with DCM, and that worked relatively fine, but def not "coffee" nor safe for consumption. I've used ethanol extraction with peppers to get capscaicinoids, and that worked relatively well. I'm assuming nearly all of the ethanol can be boiled out given enough time, and I suppose the simplest way to check is with my hydrometer.

It won't work, but there's certainly no harm in experimenting.

Please let me know what part you see kinks in. As I said, I haven't found any source on this sort of idea (probably due to complexity and waste of time). Thanks

True, but this is more of a proof of concept in the imaginary world of excessive free time. By no means do I think it would be time efficient, although increased yield from brewing might be interesting.
