It certainly has the potential to be. Remember most of the costs related to fission are safety measures, plant decommissioning, and waste disposal. If we merely had to operate the reactor without concern for those issues, fission would be incredibly cheap. The fuel costs and basic technical requirements to operate a reactor are trivial in comparison.

Fusion produced 4x more energy per mass of fuel compared to fission, isn’t at risk of meltdown, and has the potential to produce negligible radioactive byproducts. In addition, it outputs helium which is an important and finite strategic resource.

Even if the cost of fuel goes up dramatically compared to uranium reactors, it might still outperform nuclear in a big way. However, sourcing He-3 from the moon might be a lot cheaper than you think. My day job is related to space resource utilization. Transporting resources off the surface of the moon could be quite economical once we reach a sufficient level of development.

The usual joke is that fusion is always “30 years away”, not 10. The reason is that fusion projects have historically faced an issue where funding is chronically below predictions

However, this past decade is seeing a number of promising changes that make fusion seem much closer than it ever has. Lawrence Livermore managed to produce net energy gain in a fusion reaction for the first time. Fusion startups are receiving historical levels of VC funding. ITER is expected to produce as much as ten times as much energy as used to start the reaction. The rise of private space infrastructure is making helium-3 mining on the moon more possible than ever before.

Even that is meaningless because the vehicle you put a battery in is as important or moreso than the battery.

Aptera has a claimed 1,000+ mile range with a 100 kWh lithium battery. Meanwhile, the Rivian R1S has a claimed 270 mile range when equipped with a 106 kWh battery.

The main difference is that the Aptera is a light and aerodynamic car built for maximum efficiency instead of a 6,000 lb pickup truck. Any battery can boast amazing numbers if you are flexible enough with the use case.

I find it funny this comment got upvoted more than mine. I am a guidance engineer that worked at NASA on lunar lander programs, it’s literally my job to be an expert in this stuff. Modern computing has reduced propellant usage a bit and improved targeting accuracy, but we have had usable solutions to this problem since the 60s.

Atmosphere makes the problem MUCH harder because the dynamics are far more complicated and the uncertainties are higher.

Yes but a moon landing is fundamentally easier in most respects, while using substantially similar technology, than landing a rocket booster on earth or a rover on mars.

Landing on the moon is, as far as it can be, trivial for a group like NASA. It’s much more challenging for a small private company like Intuitive that has never built a lander before.

Sounds like they should let the kids choose whether they want to you outside or stay in based on whether or not they feel cold

Forcing kids to bring coats is weird to me

Maybe it’s different elsewhere, but I was born into a relatively cold+wet climate and moved to San Diego in elementary school. I didn’t bring a coat because it made me hot, I was acclimated to colder weather, and I didn’t want to carry it around.

They refused to let me go outside for recess for weeks because I didn’t bring a coat and refused to wear one from the lost and found. Finally, one day, they sent me to the principal’s office and called my mom in for a chat to discuss my misbehaving.

My mom’s response was, “You called me in from work for THIS?! If he’s not cold, he’s not cold! He has warm clothing at home. He’s capable of deciding whether or not he would be more comfortable with a jacket on. Let him go outside and leave me alone”

Same. I like the whole engagement ring ritual but I’ll be damned if our marriage is going to hinge on my “proving my love” with some overpriced trinket that costs a couple months’ salary and loses 95% of its value when it leaves the store. If that’s what it takes for us to get married it’s not the type of relationship I want in my life.

Moissanite is by far a better buy. It has more fire for 1/100th the price than a natural diamond.

But I feel like the people saying clear stones like diamond and moissanite aren’t pretty have never seen a clear, well cut, multi karat, example in the sun. The rainbow colors and brilliance from a clear high refraction stone like a diamond is frankly insane. You can see the rainbow colors shooting off of it from like 100 yards away if the lighting is right. No colored stone has quite the same wow factor as a good diamond or moissanite in the right light. That’s why diamonds have historically been in such high demand.

Opal, Alexandrite, and many other stones are equally beautiful in their own way. But it’s weird to make that point by putting down clear stones that are absolutely spectacular.

I agree diamonds are dumb and overpriced when you can get a better result from moissanite or lab grown.

That said, I’m curious why you assume it’s a blood diamond? Conflict diamonds only account for ~5% of all diamonds in the trade. Russia and Canada combined account for >50% of all rough diamonds in the industry.

That’s why I dig up my lawn every year and bury it underground inside sealed plastic bags

I’m doing my part!

The onion did a bit about ten years ago on the Palestine-Israel conflict, reporting:

“Israeli and Palestine leaders have shown they see eye to eye in nearly every facet of the proposed solution, including such provisions as: seizing all territory, watching the opposition burn in righteous fire, and building a unified nation on the corpses of their enemy. Yet, they still haven’t come any closer to putting a stop to the conflict”

Kind of sums it up.

That’s really a modern thing. It used to be that you’d buy a nice PC and 3-4 years later it can’t play new games at an acceptable frame rate and resolution.

I mean, you can Google it and find countless sources, if you really care they are readily available within seconds.

The Tl;dr is that his methods are based in dominance theory. Dominance theory has been widely debunked and the methods that arose from it are widely considered to exacerbate fear and aggression related issues in dogs. Caesar’s celebrity status has contributed to its persistence in the popular imagination.

Cesar Milan is considered a hack by almost every reputable dog trainer, and his methods conflict with every modern study I have seen on how to effectively train a dog.

If you believe this than you are woefully uninformed about American food culture.

You can get good authentic food from every region of the world here, but we also have a culture that deeply loves to create new and incredible things inspired by that foreign influence.

Look at American third wave coffee, for example. American coffee culture was inspired by the Italians, but has seen a renaissance of experimentation that makes it uniquely American. It’s now among the best in the world.

Spanish cuisine is great

But French is every bit as good

Outside of Europe? Nobody can compete with America in depth and breadth in terms of incredible food options.

Have you guys not had the salty “cheese foam” you can get on boba? It’s like stabilized whipped cream.

This doesn’t sound bad at all.

Prices for an equivalent model car really haven’t changed much after adjusting for inflation.

Hondas aren’t the best example because they have steadily been moving more upmarket as a brand. However, in 1991 a base model civic cost an inflation adjusted $15,600. A 2023 base model civic costs $23,750.

Another example that comes to mind is the Mazda Miata since people often complain about how sports cars have gotten too expensive and it’s the archetypal affordable sports car. A 1991 Miata cost an inflation adjusted $35,600. A 2023 Miata starts at $28,000.

I dunno, when I was in high school there were a number of Ayn Rand essay contests with prize money.

I won’t say they’re good books but I did make good money from reading them.
