Lasagna Battery Cell

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.

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.

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.

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 think that might be the single most hostile site I've ever tried to look at.

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.

What's wrong with it? I read the article pretty straightforwardly, the images are a bit janky but it was otherwise fine.

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!

Surprised and delighted to see a Meathead post on hackernews.

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!
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.
