This is one of those joyful concepts you learn about as a homeowner, especially on older homes.
If you have plumbing that's done in different metal materials (copper, steel, lead, etc.) and any of your pipes touch, you have to perform regular maintenance and apply a dielectric grease (another one of those single-use materials that you have to buy and store away) or your pipes could corrode and cause a ton of damage.

  So you need to regularly take your pipes apart?

I myself have found holes in foil covering acidic foods like a pot of sauce. I always assumed it was acid attack. I also switched to using the pot's lid or saran if I have no lid.
I'd like to know how much electrical energy a pan of lasagna contains and whether a discharged lasagna cell has a different flavor. Now I just need to invent a baking cell, a pan with insulated pockets so I keep my laptop and belly full ;-)

  The lasagna is the electrolyte. The energy is contained in the metals.

Interesting phenomenon I hadn't heard of before today. It looks like someone else thought to cross-post this from Reddit!

  Lasagne batteries hit the front page of reddit every couple of months. That's where I learned about galvanic corrosion in general a couple of years ago.

    I know tomato (acidic) will make holes in aluminum foil but I didn't know more than that.
    I guess today's my day: https://xkcd.com/1053/

  On a related note and a slightly larger scale:

I would like to announce I am now working on a business plan to bring lasagna powered EVs to the masses.

  Garfield is probably a better CEO than the reigning EV one.

    I don’t think we want a CEO that’s going to consume the entirety of a key ingredient in our product.
    That said, your point stands.

I recall way back in the day when Stephen Fry used to host QI, they did a bit about a lasagne battery. Sean Lock was on the panel if i remember and spun it out into a ipod-style "lasagne-pod"

The same can happen in those double walled can coolers, depending on the alloys. I put a frosty can inside one and forgot to take it out. The next day, there was a ring of corrosion at the bottom of the can cooler.

Strange, this once happened to me with a tres leches cake that I made in a metal pan and covered with foil. The next morning the foil had tiny holes and the cake was covered in metal filings!

Surprised and delighted to see a Meathead post on hackernews.

I work at Literal Labs and I can confirm as of a few minutes ago, we are pivoting to powering our TinyML models by this exciting and delicious new technology!

  Littoral labs were ahead of you powering their billion dollar ships: https://en.m.wikipedia.org/wiki/USS_Independence_(LCS-2)
  Turns out using the ship's hull as an electrode was unsustainable and lead to an early decommissioning.

I think that might be the single most hostile site I've ever tried to look at.
- floatrock5 days ago
  The guy is a pitmaster, not a web designer.
  This is a case of read the book, not the cover. The site is wealth of information on how to do all sorts of low-and-slow BBQ, both on techniques and the science behind what's going on. Pop a beer, try his Memphis Dust rub recipe, and just turn off your urge to rebuild everything in whatever flavor of javascript du jour. This isn't meant to be that kind of post.

    It is an excellent source of information! Coincidentally I looked at this site on mobile over the weekend when looking for a recipe and I do not have an ad-blocker - it is extremely hostile. Several pop-ups, auto-play videos and everything pops right back up even after you close them all. I had never noticed before using desktop but yeesh.

    unfortunately that's the enshittification reality of the proliferation of free food recipe sites. It's a rule of thumb that you need to use an adblocker anytime you look for anything recipe-related online.
    Firefox Focus is an mobile firefox flavor that has built-in ad blocking and works quite well for cooking.
    I do also sometimes open up a few physical cookbooks I bought with like real money.

  What's wrong with it? I read the article pretty straightforwardly, the images are a bit janky but it was otherwise fine.
  - 3acctforcom5 days ago
    Probably browsing without an adblocker. I do the same on my work laptop so that I don't have to factor that into troubleshooting front-end issues.
    The non-ad-blocked web is fucking insane.
