I bought over a pound of steak the other day for $5. (Yes, it was on sale. But it is frequently on sale.) Along with a potato for 50 cents, that's cheaper than a bag of Doritos. Oh, and I bought a banana for $.22. Cooking a steak takes about 10 minutes. Microwaving a TV dinner ($7.50) takes more time.

Microwaving takes less attention and less skill, though. And less cleanup. And you don’t need to own a pan. And you don’t need to own spices (steak is a bad example ofc). And you don’t need to think about the side dishes. And you don’t need to agree on what’s for dinner. And I think it’s worth repeating, you don’t need any skill and can’t really screw it up. And you don’t need to worry about it going bad because you…

Throwing a steak in a frying pan is about the same effort as a microwave frozen dinner, and is objectively cheaper.

There's no universe where processed food is cheaper.

Potatoes have a long shelf life and even then it’s not a clear win. A medium potato is around 110 calories. 15 * 150 calories servings = 5$ that’s 20.45 medium potatoes for 5$ or 24.4c per medium potato. https://www.walmart.com/ip/Doritos-Nacho-Cheese-Tortilla-Sna... The potato requires prep, 10 minutes in the microwave ~= 1/4 kWh, and presumably a little salt and butter. A microwave meal is a more complete nutrition…

Potato ------ Prep: 5 seconds under the faucet, 10 seconds to quarter it Cook: 3 min 40 sec in the microwave TV Dinner: 10 min in the microwave, $7.69 price

You’re undercooked your potatoes the goal isn’t simply to warm them, but allow your body to more easily digest them. But this isn’t just a me thing:

https://www.bigbearswife.com/how-to-cook-a-potato-in-the-mic... How long does it take to cook a potato in the microwave? Between 5-10 minutes

https://microwaveshub.com/how-long-to-heat-up-a-potato-in-th... The cooking time to heat a potato in the microwave will largely depend on the size and type of potato. Here’s a general guideline: Medium Red 6-8 oz, 4-5 minutes large Russet 7-8

I’ve literally never seen a microwave meal take 10 minutes, but I’m guessing that’s theoretically possible if it’s got enough mass to heat up.

Wait til you find out what's in a $5 steak! Our cheapest grass-fed tenderloin is $10 for a half pound cut. One. In a poor northern state. We had that cow two years and didn't supplement grain. Cheap as you can grow them. With a $5 steak, it might as well be corn chips.

The $5 steak is the steak that's on sale. It doesn't affect the food value or the taste. A pound of steak is good for 4 meals for me.

You can have your corn chips. No thanks.

The difference between removing plastic straws and reducing air travel is that reducing air travel would have an impact.

Sure, but as I said in my second example, forcing oil and natural gas companies to prevent methane leaks would have much more of an impact than reducing air travel, and requires no sacrifice for the average person. When considering which policies to advance, we should look at both the potential impact AND the democratic support for it. Climate change deniers and polluters want to paint the environmental movement as a…

The neo Calvinism runs deep. People think fixing problems involves austerity and take aways for the unelect.

It's a real problem because it has really bad political optics. And results in obsessing about 'fixing' inconsequential things or solutions that make things worse.

Obviously a choice, but also at 200mph it's obviously a vastly slower experience in a lot of way for many of the most-trafficked US domestic routes. Even at 300mph, which IIRC is much faster than normal operations on existing system, transcontinental travel becomes "too slow." The opposition would be insurmountable to making it take 12+ hours to travel from NYC to LA, for example. Effectively would split the continen…

First, 300 mph (480 kmh) is not on the cards. It's feasible technically but the energy usage rises exponentially, so it's quickly less attractive. (Obviously planes are even more inefficient for exactly the same reason, but wind resistance is at least reduced at altitude.) This is why speeds tend to top out at around 300 kmh, with only a very few prestige services (in China mainly) going marginally faster. The good n…

> Beijing to Guangzhou (same as NY to LA!) in 12 hours at an average speed of 180 kmh

I don't understand. It looks like the Chinese route is ~1200 miles and the US route is about 2500 miles. At the same 180kmh, wouldn't that imply a full 24 hours on a train?

re: LA-SF, I do think HSR could make a big dent on each side of the continent. But the reality is Americans are accustomed to crossing the entire continent quickly, and HSR is not yet a substitute for that.

This canard again [0]? You're comparing one piece of beef with a massive bag of Doritos. The banana's irrelevant, but last time you compared it to an enormous block of chocolate [1]. From experience a microwave meal should take about 3 minutes to cook so I don't know how you're taking more than 10 minutes unless, like your food item comparisons, you're cooking enough of them to feed an entire town. 0: https://news.yc…

Stouffers Spaghetti & Meatballs: 1. Cut film to vent 2. cook 6 1/2 mins on high 3. Let stand 1 min A frozen pot pie is 10.5 min. I don't know any frozen dinners for 3 min.

P.S. Hamburger is even cheaper

As to let sit time, if you can instantly pop a potato or other food into your mouth after it comes out of the microwave you haven’t cooked it.

Marie Calendar pot pie, the instructions list 5-6 minutes of time in a microwave. https://contenthandler-raleys.fieldera.com/prod/392493/1/0/0...

They do want you to let them cool, but that’s true of anything you heat to a cooking temperature in a microwave. Potatoes have the same limitations, but most people don’t include the “don’t be an idiot” instructions in recipes just cooking times.
