Corney keg with the coil inside attached to the in and out nipples........fill keg with water and antifreeze. It'll be a closed system and less messy. I have most of that stuff you might not.......why not just buy a chiller?
Because chillers are $500 and I am being cheap, and I had all the stuff except for a controller. But yes, I am saying the same thing now...Why didn't I just buy a chiller...Because attempt #2 has just failed.

I used a 50' garden hose thinking more volume and it was easier to get in there because of the flexibility. It's all hooked up, submerged in water, and the freaking hose kinked on me....It's so pretty too. Well, I have another idea....2 of them actually. Things were going so smoothly too. Ugh!

There is an old saying, "If at first you don't succeed say screw it and grab a beer and a joint and contemplate where you went wrong" or something like that.

Good idea but I don't think that would work well. Alu and copper are the best bets. They are very good metals for heat transfer. Otherwise just mesing around will cost as much as a chiller. Honestly even the corny keg would probably warm or at least be a pain to chill.....more surface area and fluid volume would cool and be a more stable temp.

Yeah I know, heat transfer, but he seemed to be happy with garden hose and this is perma coiled. As I said, fairly cheap before going to the spendy chiller. I'd try a diesel truck transmission radiator, that likely would fit in the small fridge. I rigged one of those up for my still coolant

You didn’t worry about lead poisoning?

yes.

Scientists Produce Electricity From Marijuana Metabolites
WRITTEN BY: Amy Loriaux
In a recent study, scientists were able to successfully turn cannabis metabolites into electricity. The paper, published by Dr. Tunc Canal and colleagues from Uskudar University in Istanbul in Bioresearch Technology Reports, used microbial fuel cells (MFCs; see video below). These are bio-electrochemical tools that mix chemical compounds and select bacteria together to produce electricity. The molecule in question: COOH-THC (aka 11-Nor-9-carboxy-THC) is the primary metabolite of THC (delta9-tetrahydrocannabinol), the primary compound from the cannabis plant that gets you "high".



Source: UnSplash.com
A little biochemistry first: marijuana is metabolized to various small and mostly bio-active molecules through enzymatic reactions of cytochrome p450 in the liver. Among the major metabolites of the cannabis are Δ9-THC, 11-OH-THC, and 11‑nor‑9‑carboxy‑Δ9‑tetrahydrocannabinol (COOH-THC), the latter being the primary glucuronide conjugate found in human urine
In order to get marijuana metabolites, you have to go to the source: the urine of marijuana users. If this science holds true, it would be a boon for both marijuana and renewable energy advocates. So, how exactly does it work, not the retrieval process for the metabolite (no description needed), but the electricity production? According to the paper, electricity was generated directly from air-cathode microbial fuel cells. They compared the amount of energy generated from synthetic (control) urine to marijuana users urine (as a side note, in the paper they say it was used "neat").
Both the synthetic control (with added sodium acetate as carbon source) and the COOH-THC laced urine were compared in how much electricity each produced. The MFCs work like this: MFCs employs exoelectrogenic microorganisms to extract electrons from carbon-based compounds (hence the added sodium acetate). These electrons move to a cathode and produce electrical current. These exoelectrogenic microorganisms work by oxidizing carbon-based substrates such as polysaccharides. This oxidation removes electrons from the substrate, and those electrons can then be used as electricity.

This technique has been used with such substrates as ammonia, hydrocarbons, ethanol, propanol, ethylene glycol, glycerol, cyclic alcohols, formic acid, and now, marijuana (well, okay, the THC metabolite COOH-THC). Researchers were able to extract over 62% of COOH-THC from samples. The goal of the study was to assess the feasibility of using COOH-THC. However, the researchers went after COOH-THC because there are a lot of people now out there to get samples from and it may be a good chemical to go after for future energy demands.
From the paper: "Cannabis consumption increased dramatically worldwide in recent years, and around 13% of the people in Europe was reported as cannabis users". With the increase in pot consumers in the States as well as Canada, there are bound to be more samples to produce energy from them...well, from their urine.
Below is an overview MFCs for a little technology lesson.

Better than expected, but I worked up a sweat. I used an empty 5 gal. bucket, but as you said it wasn't rigid enough and was crushing on me, so I stacked another on and doubled it up, then it was rigid enough. And the old copper I have was in 2 sections about 25' each, with flare connections so that worked out good for coiling and installing. It was easier to put one section in, and then connect them once in place. I had to run the connection lines with a high loop so the coil doesn't backflow, otherwise it drains right out....Like a dishwasher drain line. This is a temporary setup as my other rooms are full right now, so I took over the utility room for a week or 2.

I'm now thinking 100' of garden hose would have been better. My line only holds a 1-1/2 quarts of liquid, where I think 100' of garden hose would be like a gallon, and obviously that would drop my temp even more, but recovery would be longer so IDK. I can easily modify it if need be

You know I was looking at your design, me personally I am soil grower. If i was in your situation I would have expanded to coil to get more surface area to the copper, and maybe added small fans to move air as well.....just my cheap 2c ....

If it was an option, get rid of the rack, and the oval freezer area (you could possibly use that area to as a pre cooler then down) if not get rid of that too...js

Windows will not start up on my machine so I have a usb linux operating system running and I have been transfering files to usb sticks all day. I went through this before on another machine a while back, reinstalled Windows and lost a bunch of files. Yes, I should have everything backed up, hit me with a wet noodle.

Received a totally awesome sticker today F94CE010-1F6F-40C6-A0CB-98C0C4CD8203.jpeg
And I can say fo sho it was the high light of a shitty week. Thank you Mr. Bad Fish.

Ohh and on a side note, that thumb in the picture...... I stabbed it with a razor knife this morning and proceed to have hot wings for supper......neither was much fun. And if you’re wondering what the thumb did to me.....nothing......but hanging out with me will get a mofo stabbed about once a week. J/s

See i got a lot of sad faces for my post about my cat going to vet yesterday.

Figured i'd cheer everyone up. The surgery went well, they actually only removed 1/4 of his tail. After shaving his tail they were able to determine that the mass was actually a large sebaceous cyst. not a tumor. He's recovering at home, humiliated by his shaved tail and cone on his head.

Thanks for the update. I'm glad you take good care of your kitty.
